Thread: Petrol VS diesel?

Exactly. The pressures of legislation on emissions and fuel economy have made both diesel and petrol engines far more complex and has forced them to converge in most respects, making the choice more difficult. Diesel, in my view, retains the advantages of a less flammable fuel, which also has a greater energy content per litre, but will tend to be slightly heavier.

Both engines can have similar levels of driveability, reliability and durability - these depend on design and manufacture rather than whether they are petrol or diesel.

Most of the modern engines are "highly strung" and I doubt that they would last as long as most of their "lower tech" predecessors.
Do you think that your 5.6l V8 petrol would outwork/outlast the smaller 4.5l V8 Toyota diesel doing the same work?.
I have owned many V8's (Ford, Landrover, Toyota, Holden, Chrysler, Chev) simply because I Love them and all of them have been naturally asperated and all but one of them have been petrol engines.
Out of all of these V8 engines the Toyota 4.5l has been the least troublesome and the most economical of them all, It still has a ton of grunt that a V8 provides (which is why I Love them) But it does the job more reliably and cheaper than my other V8's have done.

Please tell me your kidding?? The tdv8 4.5 is the best boat anchor going around.
Injectors are common between 100-150,000kms, alternator in worst position ever, air box leaks dust, gearbox can't lock up towing heavy weight overt 90kph and over heats. They're good after you spend another $10k on top of your purchase price to get them sorted. All you need to do is gp on the FB and there's actually pages dedicated to dusted 200 motors and unhappy customers.

You must have got a good one - these engines are dogs, and neither in this one or in any alternate reality would I call them economical...

Put 'Toyota 4.5 V8' into google - the suggested search will bring up 'Toyota V8 Diesel problems' as one of the most searched - and the list is a looong one.

Compared to what? a 4l petrol Landrover engine, I don't think so.
My 79 series has done 336,000k's.
Yes it has had a new alternator, just like any other V8 or for that matter ANY engine would at that stage of its life, Alternators don't last forever.
I do agree that the alternator is in a stupid position though.
It has absolutely NO trouble "locking up" or gearbox overheating as it has a manual box.
I bought this when it had 215,000k's on it and I don't know its service history But after over 100,000k's of ownership and mainly used for towing and offroad work ALL I have had to replace is the alternator and give it regular servicing every 5,000k's.
Let me know how your 5.6l petrol engine is going after over 300,000k's

The single turbo Toyota 4.5 TDV8 is a slug of an engine for its engine capacity - low power and low torque and high fuel consumption. The engine produces less torque than a 2.7TDV6 and only a few more kw but still less than a twin turbo 2.7TDV6 and guzzles a lot more fuel for the same workload.

The 79 is more relaible than 200 cause it's down tuned and not an auto.

As for the y62 all you need do is look at them for sale in the middle East. Some with over 600,000kms and many with mid 400,000kms. They get abused dune bashing and driven hard, they are so reliable they're the number 1 selling vehicle in the middle East. "Reliable": isn't that a word Toyota somehow forgot about along the way?

Type Land Rover problems in google and you will find a huge list of issues as well.

Have a real good look through those Toyota forums and you find heaps of them are chipped,flogged,modified,and not serviced correctly.Why wouldn’t they have issues?

The number of them around is huge,so it would be interesting to know what percentage actually fail due to a manufacturing fault.

One article I read recently claimed over 250 000 have been sold just in Aus.

I know quite a few that have had them for years and never had an issue.

Many that get looked after do well over 300 to 400 000 k before needing any work at all.

Sure the alternator,and starter are in stupid places,but the alternator is very easily changed,if it fails.The auto in the 200 also doesn’t lock up at times,but the later models are better.

No vehicle is perfect,they are all a compromise.
