STUDIES conducted in Japan and Korea have revealed that counterfeit oil filters for sale online can cause serious detrimental effects to an engine.

The expert analyses concluded that the rip-off oil filters feature several design and engineering flaws, including faulty bypass valves which remain permanently open, stopping engine oil filtration. Obviously, a bypass valve should only be required if a filter becomes blocked or clogged.

This issue can expose crucial engine parts to damage and failure, and it could hit your hip pocket… hard. As a Toyota Australia spokesperson explained: “Unfiltered oil containing dirt, metal and other particulates eats away at vital engine components causing severe engine damage. This would leave vehicle owners with a hefty repair bill for a complete engine rebuild.”

As well as poor filtration, the bench testing, conducted by Toyota genuine automotive component manufacturer Denso and Hyundai equivalent Mobis, found that the counterfeit filters also demonstrated reduced service life.

Mark Skaife, a Genuine is Best ambassador, emphasised the magnitude of the issue: “If you have bought one of these filters online thinking it is legitimate, then think again because those few dollars that you think you saved could end up costing you thousands.

“Unfortunately we don’t know exactly how many of these fake filters with their dodgy materials have reached our streets. This seizure is just from one retailer, and involves over 500 filters.”

For the test, experts seized more than 500 counterfeit filters branded as Toyota, Lexus and Mobis (Hyundai and Kia), with all of the sales records collected. Affected customers are expected to hear from their respective car companies with information on the effects of the dodgy filters.

The bogus product is wrapped with labelling which looks almost indistinguishable from genuine products, so customers are often unaware they are purchasing a counterfeit product.

EGR technology explained

“From the outside, the counterfeits are difficult to tell apart from the originals, even for our trained technicians,” a Toyota Australia spokesperson said.

To curve this immeasurable problem, customers are urged to remain vigilant and take an active role to ensure they fit only genuine parts to their vehicle.

“This component test was conducted by two separate labs in two separate countries and both reached the same conclusions,” FCAI Chief Executive Tony Weber said.

“Counterfeiters are only in this for the quick buck; they can’t hope to replicate the thousands of hours of research, development and engineering that stand behind genuine parts, even with something as small as an oil filter.

“For the sake of a small short-term saving, these poor quality copies don’t even operate as a filter and risk many thousands of dollars in repair costs. It is essential that you check that your mechanic and repairer uses genuine replacement parts sourced from the authorised dealer network. It’s as simple as asking the question.”

IT takes something unique to make someone switch off-road brands, but that’s what happened to Stuart Gruchy, the owner of this sweet Hydro Blue JKU Rubicon.

Vote for the Supercharged JKU Jeep Wrangler to win Custom 4x4OTY

You see, Stuart was formerly a Nissan Patrol man, but when it came time to trade-in his Patrol, he decided to switch and take on the task of modifying one of the world’s most iconic 4x4s.

Stuart has spent wisely and progressively over a couple of years, tweaking things along the way; he originally had 33-inch rubber fitted, before moving through 35s to the monstrous 37s (37×12.5-inch Pro Comp Xtreme All Terrains, to be exact) you see wrapped around the 17×8.5-inch alloys.

Far bigger rubber than he thought he wanted. “I didn’t originally want 37s,” he said. “But after speaking to Henry at JeepKonnection and finding out their GVM upgrade package allowed for 37s, I thought why not.” The JeepKonnection upgrade lifts GVM from 2500kg to 3250kg.

It comprises tweaked heavy-duty Dana 44 front and rear axles, with a nice short 4.56 diff ratio for the bigger rolling stock, combined with ARB Air Lockers front and rear.

The American Expedition Vehicles (AEV) 3.5-inch suspension lift is made up of heavy-duty springs, bump-stop spacers, an AEV high-steer kit and ARB’s adjustable external reservoir BP-51 shocks.

Larger tyres add a challenge for gearing and powertrains, but Stuart sorted that with Bluey’s Automotive fitting a Sprintex Supercharger kit to the Rubicon’s 3.6-litre Pentastar V6. Power at the wheels went up from a stock 116kW to 190kW.

’Nuff said… Other goodies include an ARB bar with Warn CTI-S winch up front, along with three Lightforce LED 215 lights. An AEV snorkel takes care of deep breathing, and Uneek 4×4 fit rock sliders, A-pillar light mounts, bonnet-light and roof-light mounts (with Rigid Industries LED light bars).

A Rhino-Rack Backbone system (with Foxwing awning) carries gear up top, while the rear features a Kaymar twin swing-away wheel carrier and an Affordable 4×4 Drawers cargo drawer setup that includes an Outback Solutions cargo barrier, fridge slide, pull-out table, drop-down table, stove and sink, with all food and drinks kept cool by an Ironman 4×4 fridge/freezer, powered by a Genesis dual-battery system.

A Long Ranger Automotive 60-litre aux fuel tank takes care of the boosted donk’s increased thirst, while navigation is sorted via a Hema HN7, comms is a Uniden UHF radio, and an ARB compressor ensures tyre pressure changes are a doddle.

Yep, it’s a well-sorted Wrangler that is capable of tackling pretty much anything off-road, while still being a decent on-road tourer, and we reckon it is money – and time – very well spent.

MERCEDES-BENZ VANS has released the list pricing of its upcoming mid-size pick up, with prices for the 4×4 variants starting at $50,400 for the X220d Pure manual, through to $64,500 for the range-topping X250d Power automatic.

There are 11 variants across the 4×4 X-Class range and two X220d 4×2 models priced below the 4×4 models. Pricing for the V6-powered X-Class, which will be released after the four-cylinder-powered variants, is yet to be announced.

As previously reported, the X-Class will be sold under three specification grades, initially with just two four-cylinder engine choices, with auto or manual transmissions, and as a cab chassis or ute which Mercedes Benz is calling the Load Bed.

The only 4×4 variant offered with the single turbo X220d engine is the entry level one at $50,400; the rest are all powered by the 450Nm X250d bi-turbo engine.

By comparison, a double cab 4×4 Toyota Hilux starts at $43,990 for the workmate 2.4 and runs out to $54,490 for an SR5 2.8 (+ auto), while a Ford Ranger double cab 4×4 runs from $43,590 to $59,590 (+ auto) for the Wildtrak.

The Nissan Navara, which the X-Class is derived from and shares its 2.3-litre four-cylinder running gear with, starts at $38,490 for the single turbo RX manual double-cab and goes up to the bi-turbo STX at $51,990.

Aside from the engine, gearbox, 4×4 system, basic chassis and side glass, the X-Class shares very little with the Navara.

The chassis is modified with extra bracing and cross member to improve NVH and dynamics; the wheel track is wider using a bespoke disc-braked rear differential and longer front control arms; the body and cargo tub are wider than the Nissan; and the sheetmetal is all Mercedes-Benz.

The X-Class Pure is the farm-spec model and is distinguished by its front and rear black bumpers, 17-inch steel wheels and vinyl floor coverings. Standard equipment on the Pure includes halogen headlights, power adjustable door mirrors, black fabric seat trims, rear view camera (not with Cab Chassis), Audio 20 CD infotainment system with 17.8cm TFT touchpad, manual air-conditioning system, tyre pressure monitoring, active brake assist, and lane-keeping assist.

The mid-spec Progressive adds body-coloured front and rear bumpers, 17-inch alloy wheels, heated outside mirrors, heat-insulating glass windscreen, rain-sensing wipers, Garmin® MAP PILOT navigation, floor carpets, grained instrument panel in black, model-specific black seat fabric, leather-trimmed steering wheel, shift lever knob and handbrake lever, door sill panels in aluminium and illuminated front footwell, Digital Audio with eight-speaker system, and a chromatic rear view mirror with compass.

Option packages for the Progressive can include dual zone climate control air-conditioning, 360-degree surround camera and an integrated COMAND sat-nav with a bigger screen, among other features.

To get all those features standard you need the Power specification, which adds chromed trimmed front and rear bumpers, 18-inch alloy wheels, LED headlights and part-LED tail-lamps, ARTICO man-made leather trimmed dash and seats, power adjustable front seats, COMAND online multimedia system, navigation and touchpad, 360-degree Camera, PARKTRONIC parking assistance system, digital audio with eight-speaker system, automatic climate control a/c, and keyless starting.

The X-Class 220d and 250d variants will go on sale in Australia in April 2017, with the V6-powered X350d arriving in the third quarter of the year.

PRICING

All prices shown are manufactures list and do not include extras.

TOYOTA has officially released range and pricing details for its highly anticipated 2018 Land Cruiser Prado.

Reduced pricing and increased towing capacity across the five-model line-up are the biggest changes to the Prado range.

Prices now start from $53,490 for the GX manual (despite the addition of sat-nav and Toyota Link), while choosing the GXL manual variant will save you the most coin ($1200).

Full pricing here:

*GX or GXL variants driven by an automatic transmission will cost an extra $3000.

In the other big change, the towing capacity for all automatic models has been increased by 500kg to 3000kg.

The motoring public received its first glance of the Prado back in September this year at the Frankfurt Motor Show in Germany. Noticeable at the unveiling were the aesthetic updates to the bonnet, fenders, grille and repositioned headlights, all claimed to improve off-road manoeuvrability.

The 2018 Prado will retain the same mechanical package as the outgoing line-up – GD 2.8-litre, four-cylinder diesel engine mated to six-speed automatic or manual gearboxes and full-time 4WD with low range – but the V6 petrol engine option has been shafted.

Importantly, lower grades – GX and GXL variants – will now come standard with driver-aid technology features that were only available in Kakadu and VX variants. Features now standard include lane departure warnings, a pre-collision safety system and automatic cruise control.

The VX now gets a blind spot monitor and rear cross traffic alert as standard, and the Kakadu retains all the top-notch features and tech.

A rear diff lock, also previously only available with the top-spec Kakadu, is now standard with VX and GXL grades.

In October, 829 Prados found new homes, giving it a 10 per cent share of the large SUV (<$70K) market. On the year-to-date charts, 12,900 Prados have been sold so far, which is a 4.3 per cent gain on 2016 – putting it atop the large SUV (<$70K) sales charts.

WHETHER it be a daily driver or purely for recreation, when most of us dream about a new 4×4 we have to compromise.

This was first published in 4×4 Australia’s December 2011 issue.

But when Holden Rally Team supremo Kees Weel considered his new 4×4, he faced no such angst: the new HRT Colorado would have only one objective – to win the Australasian Safari.

But such a vehicle already existed. Last year’s winner – driven by Craig Lowndes with Kees in the left-hand seat – was sitting in the foyer of Paul Weel Racing (PWR) needing little more than some fibreglass work and an oil change before heading to Western Australia for the 2011 Safari – so why clone a new one.

“The ‘old’ one was first driven in the Safari by Peter Brock back in 2004,” explains Kees. “It won the event in 2007 with John Hederics and John Williams before Craig and I won last year. Our plan is for me to navigate for (son) Paul with Craig and John Panozzo in the proven unit.”

Both vehicles are based on Holden’s Colorado Spacecab Ute and while they retain the original chassis and cab – including doorskins – almost everything else is custom engineered. More like built from scratch than modified, even if many of the parts are standard.

The major difference between the builds is the powerplant, the newer model being upgraded to the 6.0-litre V8 where last year’s winner retains the 5.7-litre unit.

Kees waved away the dynamometer figures declaring that HRT are not into bench racing and that – like Rolls-Royce – the power is adequate. Certainly it should be reliable as both engines – at around 330kW and 500Nm of torque – are no more stressed than thousands of HSV models released over the past decade.

Keeping the power and torque in the right zone is controlled by a Hollinger six-speed sequential gearbox, with the same ratios as the V8 Supercar units. To ensure this mass doesn’t become wedded to the ironstone boulders of Western Australia’s goldfields, Alcon 315mm vented discs and four-piston calipers are employed at each corner; a big increase in braking capability over past years.

Whilst it’s inevitable, looks spectacular, and may save on tyre wear, getting airborne doesn’t really aid forward progress and it’s the dark art of keeping the rubber attached to terra firma more than any other factor that separates the winners from the also-rans – never mind the many DNFs due to suspension damage.

For many years Murray Coote has been the go-to man for suspension and Murray is responsible for each of the eight handbuilt shock absorbers it takes to keep the Colorado moving swiftly across the landscape no matter how rough the terrain.

Holden Colorado Superute revealed

All of this expense and expertise would be pointless without the appropriate rubber which in this instance is the same BF Goodrich Rallye Raids worn by most Dakar and Safari winners over the past decade. The HRT vehicles run standard 16-inch alloy rims and 235/85 profiles, giving an overall rolling diameter of 808 mm.

If you’d like a set just ask for the G1 Rock spec and get your wallet out. Five grand will see you out the shop with a spare on the back – but remember they’re for competition use only and each set might just see the day out as long as you don’t get a puncture.

HRT’s Peter ‘Pops’ Glennie is the man in charge and maintains pressures should be set at 28psi, which will increase to 40-42psi once the driver gets angry. This significantly decreases – but will never eradicate – the incidence of punctures which can quite easily cost a race win.

Three spares are carried in quick-release ratchet straps directly behind the 350-litre fuel tank in the bed of what would normally be a ute tray –shortened by 150mm to provide a better exit angle and, with the huge inner wheel arches, fuel tank, workshop jack, base plate, shovel and tools there’s only just room for a couple of oil coolers and fans.

The devil is in the detail and everyone has heard a story about a million-dollar race effort being brought undone by the failure of a 20-cent part. No one has learnt the secret of how to eliminate this risk entirely but the Holden Rally Team has the combined knowledge to reduce it to a minimum.

The trio of Kees Weel, Peter Glennie and John Hederics have participated in more than 40 Safaris and hundreds of other off-road events over the past quarter-century. They have first-hand experience at – just about – everything that can go wrong, which allows them to focus on the unknowns.

Which is why, a full six weeks out from the Safari, both vehicles were fully fettled and ready for back-to-back testing on Peter Glennie’s private test tracks north-west of Moree.

Other than rolling tests to ensure that all systems were working as they should, the prime purpose of the two-day test session was to evaluate suspension settings and tune the airflow for optimal cooling.

Minor issues involved testing the gauge on the mesh of the radiator protectors and the possible addition of a couple of vanes to deflect airflow to the engine bay better. It was then time for Craig to take everyone for a ‘spin’. Five minutes was fun but I don’t know about five hours – even though the ride was remarkably smooth.

Craig has adapted easily from the 450kW he enjoys on the blacktop to 330kW on the black soil; and judging by the results last year where he slotted a Safari win between his Supercar victories at Phillip Island and Bathurst in the space of three weeks it was all looking good for a repeat.

The first two days of the 2011 Safari proved both PWR-built cars were winners with Paul and Kees fastest in the prologue and the Lowndes/Panozzo car in front at the end of the first day.

But the crews aren’t racing one another, the Safari is really the ultimate speed trial to test who can best avoid all the obstacles mother nature has strewn across the landscape.

And while all forms of motorsport have their dangers, there are no run-off areas or tyre barriers in the bush where every hardened branch appears to be engineered to puncture a tyre or radiator, every rock positioned to do maximum damage to the suspension and every bulldust hole ready to swallow a wheel assembly.

It was a dead mulga tree, or maybe two, that stopped Paul’s car in its tracks with enough damage that it was decided to keep all spares available for Craig’s car. Craig and John built on their lead every section and by the end of day four enjoyed an almost insurmountable lead.

However the mulga remained malicious, Craig clipped a stump and tipped the Colorado on its side. The team repaired the damage overnight and the Colorado stormed back through the field to finish fourth. But, like Arnie, they’ll be back – next year.

ONE-ON-ONE WITH CRAIG LOWNDES

The 2010 Safari was your first off-road event, and that in a car you’d never driven before. How did you prepare? Well I grew up on a property and I’ve always had dirt bikes and paddock bombs to play with but I’ve never really been into 4X4s, so it was a steep learning curve but former Safari winner John Hederics knows the car back to front and helped me to get a handle on it.

It appears you became very comfortable fairly quickly. Last year was the first time I’ve really driven a 4X4. As the Safari went on I became more comfortable and learnt how to position and slide the car and get it to the end of the day – and not to get a flat.

It all went belly up this year. How did it all go wrong? We’d built a comfortable lead and were first car on the track but we had to press on because even something simple like a flat tyre can cost you the lead. I slid into a dead tree, which tore out the rear suspension and that was our race.

What’s it like having someone next to you calling the shots? Having someone beside me was another thing I had to get my head around. If I have a crash it’s my own fault and I’d be the only one likely to get hurt. Having someone else to worry about was quite different, though the cars are incredibly safe.

How much different are the V8 Supercars to the Safari? V8 Supercars runs as a business. It’s a great job but there’s no novelty. It’s really great to do the Safari, not knowing how hard or fast it would be, not knowing the competition.

Peter Brock had a great affinity with the Safari. Did that influence you? Peter loved the Safari and tried to win it a number of times, so our win in 2010 a great sense of achievement. It was as tough an event as I’ve ever done; like getting up and doing the Bathurst 1000 every day. But it’s a lot of fun and the camaraderie around the bivouac is terrific. Given the opportunity I’ll be back. The Safari is just like racing was 20 years ago.

JEEP has released more official images of its forthcoming JL Wrangler ahead of its November 29 official unveiling at the LA Auto Show.

As the global launch is underway in New Zealand, these images reveal more of the evolving Jeep body in two-door Rubicon and four-door models, plus provide a good look at the interior.

The JL will hit US showrooms later this year but won’t get to Australia until late in 2018, around the same time that Jeep is expected to release the double-cab pick-up version.

The JL retains a body-on-frame construction and live axles front and rear on all coil suspension – and expect the off-road-oriented Rubicons to have low gears and locking differentials.

Powertrains will start with the carried-over 3.6-litre Pentastar petrol V6, but a powerful turbocharged four-cylinder petrol variant will be offered to help lower overall fleet fuel-consumption numbers.

The diesel option is tipped to be the 3.0-litre V6 VM Motori mill as found in the Grand Cherokee but, again, buyers will have to wait up to a year for that option. All engines will be backed by an eight-speed auto, with a manual gearbox available.

Keep an eye on www.4x4australia.com.au for our first drive of the new Wrangler in December.

YOU don’t see many camper trailers at the SEMA Show, so it was a big call for Justin, Sarah and the team to display Patriot Campers’ products there in 2017.

Patriot now has a distributor in the United States, and the products are proving popular as they are unlike anything else the Americans are used to.

To really garner some interest, Justin took his ‘Black Truck’ Land Cruiser 79 to SEMA and that really set tongues wagging.

Like high-end camper trailers, The Yanks don’t get LC70s there and they seem to love the functional style of the Patriot Super Tourer.

We caught up with Justin on the Patriot stand at the show.

ANNUAL leave has been approved and the fourby is ready to roll. Now it’s time to get some top quality aftermarket kit for your Christmas getaway.

YAKIMA SHOWDOWN Just in time for summer, Yakima has released the ShowDown. This load-assist setup provides between 30 to 45 per cent weight assistance (figure dependent on boat width) when you are loading your watercraft on top of your vehicle. The load limit is 36kg – plenty for a river/sea kayak or two SUPS. The universal mount system fits most racks (the ShowDown can’t be used with clamp-style roof-racks), is easy to fit and folds down flat when not in use.

The ShowDown brings the boat holders down to waist level (tilting down approximately 650mm), making loading your watercraft onto a tall 4×4 a doddle. The felt-covered cradles prevent scratching/damage and are designed to flex to conform to your kayak’s hull. All tie-down straps are included. Website: www.yakima.com.au

I FIRST saw this rich-red GQ Patrol tray-top with a colour-coded Candy Camper up in Cooktown, and from the sweet burble issuing from under the bonnet, I knew it was something more than a 4.2-litre turbo-diesel.

This was first published in 4×4 Australia’s April 2011 issue.

The next time I saw it in its farm attire, just outside Loxton in South Australia’s Riverland, where owners Dudley and Iris Jackmann wrestle a living from grapes and cattle agistment.

This Patrol is something else. It started life in 1997 as a standard 4.2 normally-aspirated diesel, which soon had a turbo on it to boost power production.

From darn-near the beginning, the Patrol has also had a suspension upgrade with a 50mm lift from an all-round set of Pedder Trak Ryder foam-filled shocks and heavy-duty coils. BFG 32-inch tyres grace a set of highly polished 15 x 8 CSA alloy Magnum rims – one of the few rims around that are rated to carry a load of 1250kg each.

An Airtec snorkel was added along with a Gitsham alloy bullbar and, down the back, a smart-looking Gitsham alloy tray. An electric X9000 Superwinch and a pair of Hella 100W quartz-halogen driving lights grace the bullbar. While the rear diff is standard, the front has a Lock-Rite auto-locking diff fitted for that extra traction when you need it.

Under the bonnet, the Jackmanns fitted a dual battery system with a 4WD Systems isolator, while down the back end another 90-litre Nissan tank was added to increase the fuel range. An air compressor has been fitted inside the engine bay and air hoses plumbed into the vehicle with fittings at the front and rear provide air on tap for tyres and the rear suspension airbags.

The cab wasn’t left alone, either, and while the standard Nissan bucket seats are fine, a small fridge nestles between them. An overhead console holds a few CB radios and the dash has extra gauges to monitor turbo boost and exhaust gas temperature.

A Sony stereo replaces the old clunker that was fitted originally to the ST Patrol, while a voice-activated Garmin GPS/streetPilot, hands-free Bluetooth phone connector and reversing camera are the latest electronic gadgets to find a home in the cab.

Then, for its 10th birthday, a heart transplant marked the beginning of an incredible transformation.

Dudley bought a 6.5-litre V8 Chevy engine from Brunswick Diesel, complete with ceramic pistons and new manifold, turbo and alternator. A Chev clutch and a Marks 4WD Adaptors adaptor plate allows the V8 to mate with the standard Nissan five-speed gearbox. To help keep the engine cool, a five-core copper radiator also came from Brunswick.

To allow the new engine to fit more easily, Dudley, with tradie assistant Iris, spent hundreds of hours fitting the engine and custom building many of the necessary items that bolt to it and the body. First project was a 50mm body lift, while the firewall had to be remoulded and pushed back 25mm to allow room for the dump pipe from the turbo to fit more easily.

Then most of the electric wiring was stripped out and custom looms made to replace the older wiring and to link with the new engine.

Heavier-duty springs were fitted to the front and a spacer added to the bump stop, while all of the suspension components had their bushes replaced. To give the tyres a bit more clearance within the front wheel arch and to help overcome the lack of clearance between the starter motor and the diff housing, a 10mm spacer was added to the front suspension’s trailing arms, which essentially pushes the front axle forward.

A 3.5-inch custom exhaust was next and then, while one snorkel may have fed enough air to the old engine, it was left wanting when it came to the V8. After a lot of searching, an Airflow snorkel meant for a 60 Series Cruiser now graces the driver’s-side pillar, ensuring the engine gets enough air when the foot is pushed to the metal. More importantly, it looks like it was meant to be there!

To ensure the V8 engine got clean air, Dudley built two stainless steel air boxes and fitted them with K&N air filters. Two beautifully designed and built air inlet hoses run from the boxes via a pair of stainless water-cooled coolers to the inlet of the turbo.

The coolers are fed water stored and cooled in the alloy bullbar, via an electric pump mounted behind it. It’s not an intercooler, but it ensures the engine is getting air as cool as possible. For outback trips and to get to places where their large caravan couldn’t go, the Jackmanns bought a Candy Camper and colour-coded it to suit the red Patrol. It looks good!

Two 50-litre, food-grade alloy water tanks were custom made and fitted to the underside of the tray just behind the cab so that the Jackmanns could be independent for longer periods. One of these feeds a stainless steel custom-made hot water heater, the heating coil fed water from the engine radiator.

When it is activated, the heater can warm the water in the tank to shower temperature in about 20 minutes of engine running.

Then, in 2009, in the ongoing quest for more power, Dudley decided to fit gas injection to the Patrol. He acquired a Diesel/Gas Australia kit and set about fitting it himself. The 34-litre gas tank was fitted under the rear tray and above one of the fuel tanks while all hoses were run in protective conduits to the front, where the gas runs through a regulator/mixer and a filter into the turbo.

An electronic black box helps control gas injection and Dudley has played with different jets to improve performance and economy, while Diesel/Gas Australia has re-programmed the unit to suit.

Dudley added a gas shut-off switch, which cuts gas to the engine when he is on a trailing throttle. The turbo currently runs about nine pounds of boost and, using a gas and diesel mixture that is about 20 percent gas.

While the Nissan hasn’t been on a dyno since the gas injection went onto it, the V8 should be pushing out around 155kW of power at 3400rpm and 500Nm of torque at around 1700 revs.

I was lucky enough to get behind the wheel of this immaculate GQ and to take it for a quick blast on some of the dirt roads around Loxton and the Murray River. The push back into the seat when I floored it proved Patrol has lots more … lots, lots more than a standard 4.2 turbo! And when the Patrol is lightly loaded, like when I drove it, it is oh-so-easy to spin the wheels in first – and second!

With a flick of a switch on the dash you can turn off the gas injection and once again you feel it (there’s about a 20 percent difference, according to Diesel Gas Australia), especially on a hill under full throttle. The gas injection makes towing a lot easier and safer.

Importantly, all the work has been engineered and certified. I reckoned it would have breezed that in because it is, without a doubt, the best-presented Patrol I have ever seen, while the engine conversion is the finest I’ve seen done in a 4X4, bar none.

The vehicle is no show pony, either, with Dudley and Iris getting out bush and taking the rig to Cape York, Fraser Island and throughout the desert country of our outback in the last couple of years. Isn’t that what all

THERE are some interesting insights in Deano’s Bulldust column this month on the changing perceptions people have of four-wheel drivers.

I guess it was inevitable that people would become more accepting of 4WDs when every second person is driving an SUV or 4×4 ute. When I’m driving around town I always try not to be the person in a 4WD that cuts someone off in traffic – the one who fuels the fire of anti-4×4 sentiment.

However, these days, the car I’m letting in or waving through is just as likely to be a 4×4 or SUV of some sort. They are the chosen mode of transport for Australian families and, with Australian car manufacturing ending this year, and with it the large sedans Aussie families once loved, there will be more folks buying into the SUV fold in the future.

The car companies are ensuring there is no lack of choice in the segment, with hundreds of new SUVs on the market – unfortunately for us, the number of vehicles with authentic off-road ability aren’t growing as quickly.

In the New Year we’ll have the Jeep JL Wrangler to look forward to, as it promises to keep the tradition alive with live axles hanging off a separate chassis and a host of features that will stay true to Jeep heritage.

Suzuki has shown its all-new Jimny, which is also set for a 2018 launch and, while details are still thin as we go to print, we hope it will continue to be the great little off-roader it always has been.

There will be a few changes for 4X4 Australia magazine in 2018 as well. For a start, we’re trying to bring the cover date back in line with the calendar; so when you see the next issue (issue 408) which comes out in December, it won’t be labelled January. Issue 409 will be the January 2018 edition and it will be coming out in, believe it or not, January!

We hope it doesn’t cause too much confusion, but it should make it more logical in the long run.

The mag will look a bit different as well, specifically with how our regular columns are delivered. They’ll be alternating from month to month with their tales and stories from around the country. We will be losing Viv Moon’s Camp Cook page from the magazine which, after near-on 30 years of recipes, has kept many a camp well fed. If you miss Viv’s camp recipes, you’ll still be able to find them via her cookbooks and online at Ron and Viv’s website.
