Advantages v disadvantages of a diesel!!!

Depending on when you do it and if you are buying new or used things will have changed the constant upwards trend in petrol prices loots set to continue as dose the major car manufactures push towards tdi for the main stream. Most of continental Europe doesn't have the UKs fuel snobbery so development or engines is profitable especially combined with there generally lower pump prices compared to petrol. As the country runs on derv the pressures to keep the tax on in down is greater than that for petrol so we could well see a reversal in the current couple of p/l price diferance.

That's incredibly low.

The DTurbo I drove at the weekend redlined higher than that, ffs!

In other words you are again out of your depth and can offer nothing...

Oh, I'm sure with a quick reference to my old university books I could find a theory that would prove the moon was made of cheese, but what's the point when real world experiences say different.

Yes IME.

Strange, I've not heard of problems with turbos, pistons, rings and big ends. Head gasket seems to be the most common one (not that I know anybody who's actually lost theirs), and I do know somebody who broke his by having the swirl chamber drop out. And no, I've not priced up the shagged injection pump at 80K - never having had one die like that n'all. The one I do know of which failed at a rather higher mileage got replaced, as the couple of hundred quid it cost was less than a replacement car with an unknown history.

cheers, clive

Refer to post one. I already know they are nominally more fuel efficient, mostly due to the high compression and the always "lean" way they burn fuel, and not because diesel is 5 percent greater calorific value incidentally.

I am still waiting for som real logic based evidence in support of any of your claims, which so far you have not been able to do, as expected.

And the reason it can be geared thus, is... :0)

I've not stood specifically by one of them, but I have by other stuff like the bigger Merc CDis... they're hardly intrusive, inside or out, even with the bonnet up.

Evidence of what?

I'm struggling here as you seem to be missing the point entirely.

Spouting scientific theories as to why a diesel costs more to run whilst wearing out faster seems to fly in the face of all the real world experiences of them - so I fail to understand why you're sticking to something you once read in a book when all the evidence says it's bollocks.

If anyone is snipping bits they don't like it's you.

Like the evidence that a modern diesel will run to quite silly mileage without major expense. Regardless of what your books say, it's a true fact that can't really be argued against.

Yes as long as nobody has to be too near one and any kind of refinement doesent matter!

No mocking. Just keep requesting the logical reasoning behind your claims. And i dont care what your preferences are about see post one, this is about facts.

Some people like pain, its their choice, as I said nothing to do with the facts.

Not relevant to discussion only to you.

YOU are one person, the industry as a whole does not agree When they were non turbo and less stressed they were more reliable but not any more.

I have had loads of diesels, last one was a vw 2.5 turbo diesel I have been in loads of diesels too, and taken more of them apart than most people have.

Insults again from the uneducated that cannot explain themselves!!!

I've actually bothered to

I don't have ideals! I use logic and facts and experience to make my decisions

I've come to my conclusions through a reasonable

I dont mock, You think every fact that goes against diesels is some kind of personal attack! You are unable to seperate one from the other, bit like a thick football fan, all gob and no notion.

A noise meter says you are wrong, in most cases.

Yes they are I can hear them fire up in the car park accross from my house with the windows shut!

Economy is not and never was in question and yet again you drag it up in some sort of defense!!!

I have no interest in your finances or rather lack of, as its got sod all to do with the comments on post 1

Some others get used to or put up with it because they cant afford a proper car. But as I said your personal preferences have nothing to doo with the argument presented on post 1 (again...)

But nobody is interested in your personal preference only the facts.

And all this stuff about wearing out faster - the extra stresses inside the engine block/head are countered by the fact that things are made to withstand more stresses to start with. And the whole wear issue is *very* largely negated by the fact that the diesel fuel itself acts as a lubricant for the bores, meaning things can quite easily last a very long time.

Problem is, a lot of people thing diesels are absolutely invincible, and abuse them to no end, with the belief that they'll never break. It's diesel engines in vans/cars driven by these people that end up breaking, due to sheer volume of abuse.

You get it with petrols as well, but aye... some people haven't even the least amount of mechanical sympathy for their vehicles, and then wonder why they go bang.

recent as in 54 plates

but he did say that the C70 he had was much quicker, even though the economy was a lot poorer

but there aren't that many manufacturers who run both na and turbo'd engines of the same capacity are there unless you count Saab and they are basically gm products you could also admit Subaru and a whole host of oriental cars that don't really sell huge amounts

They do.

But they do.

Bollocks, they clatter like a rusty old sewing machine, all of them.

No it can't.

Umm no that's a fallacy promoted by people who don't understand science. The commonest type of person proposing these views is the humble maintenance technician - enough college education to wield a spanner, not enough experience to avoid stripping threads and a knowledge of science picked up from reading the Beano.

I would speculate for a number of reasons:-

Diesels tend to be more about economy that other characteristics The engine has a narrow range of revs There's a blower (or in the case of this BMW, two blowers in sequence, and small one for low revs to provide drivability, and a big one to provide some power out of the thing)

Don't get me wrong, I'm not suggesting they're deafening. Moreover that they sound agricultural when starting and at tickover.
