Petrol v Diesel

The never ending argument … the petrol versus diesel debate.

This old campfire argument has been going on for years and will probably never let up. Everyone has their own opinions and reasons for choosing what they buy. Well for now they do.

That is unless the influential parties with reasons to gain from limited choice have their way.

It is interesting that one of the things we’ve notice over the last few years is the increasing demand for modern diesel engine rebuild kits. There has been a resurgence in demand as modern engines start to fail with less kilometres travelled than my pushbike.

Most 4WDers are aware of the hand-grenades Nissan brought out in the early 2000’s with their 3.0L Renault motor, but the Hilux/Prado D4D is also causing serious grief, and even the Landcruiser V8 twin turbo engine rebuild kits are selling faster than spark plugs for my old 1FZ-FE engine. What has the industry done when some of the early diesel engines like the venerable 1HZ and TD42’s are still running original glow plugs.

Here’s my opinion … our European mates have stuffed us all up.
They’ve have been running around in diesel Citroens, Renaults and Golfs for years, smogging up their beautiful cities. Diesel fuel ‘was’ dirt cheap which drove their preference to these slow but economical buzz-boxes. The black diesel smoke have driven their authorities to imposing strict rules on emissions that manufacturers are simply struggling to meet. They have essentially tweaked, tuned and turbocharged these smaller and smaller engines to within an inch of their life before releasing them across the world. However our larger spaces and lower fuel consumption volumes at some fuel outlets mean risk of contamination is higher as is resultant engine failure.
But we are a bit different here in Australia, we don’t have major towns within 30kms of each other, ours are about 300kms apart.
We lug big our 4WD’s and heavy loads for thousands of kilometres on holidays.

Old schoolers will swear by diesels for crossing rivers without concern, but times have changed, this is no longer the case with modern diesel engines covered in electronics and wiring just as susceptible to water as spark plugs are.

Plus roads and even tracks are much better than they were even 20 years ago.
So you can throw that argument out.

Car manufacturers, oil companies and associated big industry players are eyeing off a lucrative future of servicing high tech diesel engines that are now more complicated than most petrol engines. Its almost turned a full 180 degrees. Even the motoring clubs and insurers are pushing the diesel option in their surveys and tests. A small comparo dug up off the interweb shows the real operating cost differences are minimal. But not when it comes to repairs and this is something car manufacturers, dealerships and motoring authorities are not telling the public.

The current cost of repairing a modern diesel engine is horrendous, and isn’t going to decrease.

So one has to wonder if the V6 petrol powered utes and V8 petrol powered wagons are actually going to start finding themselves higher up on the shopping lists. Nissan have seen new car sale prices of their Y62 Patrols vary considerably but don’t be surprised to see the petrol engine 4WD’s start to gain favour as diesel owners get sick and tired of the reliability and cost issues being found with this new breed of high tech, extreme tolerance diesel engines.

    Well done Chris great article anyone who truly researchs modern diesel issues and the cost to repair them would not even consider them but unfortunately most 4×4 journalists back there magazine sponsors even if it means flogging a dead horse

    Good to see word is getting out. Ive had a number of diesels and petrol 4x4s. Water xings havnt been an issue for petrol motors in years. My 1st 4.5lt GU in 2000 never had problems. So not sure why people still think that way.
    As for reliability, none of my diesels have been as good as the petrol 4x4s. Ive had 2 4.5lt GUs, even a v6 Jakaroo, plus the 2.8lt and 3.0lt GU and 4.2lt work ute diesels.
    The new y62 is by far the best 4×4 ive had. Its way more capable out of the box then the GU and even mod for mod its a step up. Plus no common issues with the vk56 5.6lt petty v8 thays been around for well over 10 years now.
    New tech in these engines gives it comparable economy to the ttd cruisers with 25k less purchase price (toyota tax).
    So any1 still spouting dribble about petrols being gas gusslers havnt seen these new y62s. Sure when u use all 400 hp it will use more. But drive normal driving sees awsome figures like 10lts/100 on hwy, my avg is 15.6lts/100 since new and at 70k kms doing about 20k of those kms offroad and remote touring, u cant really complain.
    I say good bye to modern diesels.

    I have heard recently from a trucker that the Government has had sulphur removed from diesel fuel in Australia. This he believes has caused the problems with modern diesel motors mainly injectors failing. I tow a caravan and drive a 3.0 litre diesel, and over the years have found that in our very hot climate that there is only one motor type that can handle large towing loads with constant heat and keep the comfort that we all expect now days i.e. the air conditioner on and that is a diesel motor. Petrol motors towing in 40 plus degree temperature days are prone to over heating or only running without the air conditioning working.

    maintenance is the main issue with any vehicle. but here in Australia out main problem is our fuel quality.
    but future is going to be electric

    This Article is well written, no doubt it hurts the Diesel loving brigade to read it as the truth often hurts.
    Pollution control measures really have taken their toll on our reliability of Diesel engines, however the technology advancement in modern petrol engines has really removed the shortfalls as why we all switched to diesel in the first place. Economy for one is closer now than it ever has been before, water crossing is no longer an issue and engine life… well maybe the table has turned on this one!

    Mate that’s just wildly incorrect. Go and do some research and try again, actually talk to real people doing exactly that, I lived and toured the Pilbara for 6 years and a petrol 4×4 was the best I ever owned. Gets a bit warm up there in case you’re not aware. Also consider that the middle east is also an extremely hot climate, guess what engines 90% of 4x4s there use….petrols.

    Agreed, and on topic with the article which is going to react poorly to bad fuel…I had to get a flat bed from karijini national Park to Tom price in my diesel D40 due to poor fuel, red engine light came on and I went no further, I was considered lucky that I only had to fork out a grand to have the entire fuel system flushed, poor fuel in a petrol? It might ping? Most modern ECU’s can detect poor fuel and wind back timing etc to compensate and preserve the engine, you can keep a couple bottles of octane booster in the car, you’ll keep moving though, reliably.

    After owning 2 Transit van diesels with Bolt on fuel injectors I liked early diesels. But then moving to Australia we owned a short lived Holden Jackaroo diesel, which broke down twice in a week only to be told diesel fuel was getting into the engine oil. No garage would touch it, so we had to take it to a Holden dealer.
    We had new fuel injectors at a cost of $5500 replaced with the engine still making a banging noise. After months of stress, VCAT claim on Holden and selling the Jackeroo for peanuts, We bought a Toyota Prado 4.0L petrol. Its costs more to run than a diesel but if it breaks down we know it will be cheaper than a diesel.

    Most of you are correct the modern day diesel a not as bush reliable as they were my personal choice is old school diesel hance I can fix most things my self the diesel petrol debate well that can go on for ever I keep diesel be cause I can carry a hell of a lot more safely I do a lot of remote trips
