1. Diesel Engines are more expensive to produce than petrol, thus diesel engined cars are proportionally more expensive.
2. They cost more to maintain especially as most of them are turbocharged to make them perform like petrol engines.
3. The average man in the street who drives a diesel, drives it like a petrol. Some wear out the turbo and are therefore faced with more repairs.
4. Most of them suffer from terrible turbo-lag which makes them unpleasant to drive.
5. Diesel is more expensive than petrol and the gap is widening.
6. They stink
7. They are noisy
8. They polute the atmosphere. The majority of photographic smog in big cities is caused by diesel vehicles.
9. All in all they are thoroughly unpleasant and the person who invented them should have been strangled at birth.
10. I voted for Petrol:lol:

All the above is very much IMHO and no offence to all the diesel drivers:)

:rant: over

I can't disagree with you personally, although I do think diesels have a place in certain applications like trucks, buses, tractors and ships.

However they depreciate less, so its swings and roundabouts there.

2. They cost more to maintain especially as most of them are turbocharged to make them perform like petrol engines.
Granted turbo's can fail and that is costly, but diesels tend to take high mileages a lot better than petrols, and they are a lot tougher. Something like head gasket failure is very rare on a diesel, as is a snapped cambelt. There are also no spark plugs to replace. Just some glow plugs, which aren't usually on the service schedule anyway, indicating that they are expected to usually last the life of the engine. My JTD used no oil, no coolant, nothing between services at all, and it costs more for an oil change on my V6 than it did on my JTD. So I would disagree with you that diesels are costlier to maintain.

3. The average man in the street who drives a diesel, drives it like a petrol. Some wear out the turbo and are therefore faced with more repairs.
How do you drive a petrol then, as opposed to driving a diesel? Are you talking about a normally aspirated petrol? As 99% of the time I see people driving their petrol engines in the rev band that you would typically associate with a diesel engine, ie under 5,000rpm. Why own a petrol if most of the time you are barely getting up to peak torque, never mind peak power? I think the low down shove from a diesel is ideal for day-to-day driving.

Anyway, a turbo wears out due to maintenence issues rather than driving style. My JTD was sold with 122k on the clock, on its original turbo, my current daily driver, ten year old Mondeo with 146k on the clock, still on original turbo. Contrary to what some people believe they don't wear out often, if they do its usually because of a design flaw with that specific car (eg previous model BMW 320d)

4. Most of them suffer from terrible turbo-lag which makes them unpleasant to drive.
The Mondeo I have has terrible turbo lag. No torque until 2,000rpm. However, last time I drove a 1.8 petrol it seemed there was no torque anywhere in the rev range! :lol:

My JTD didn't suffer from turbo lag though, it had masses of grunt anywhere in the rev range, and was nothing like unpleasant to drive. That tidal wave of torque is definitely just as exillerating as the revs building towards 7,000 in the V6 I drive now. Plus you can use that torque all the time :)


5. Diesel is more expensive than petrol and the gap is widening.
Can't argue with that, but Mondy doesn't mind half the tank being full of cooking oil at 50p a litre.. ;)

You can't do that in a modern diesel though.

6. They stink
The fumes aren't nice, but the fuel itself smells nice.

7. They are noisy
I think you meant to say they sound terrible. Thats what I would have said anyway, you can't argue with the fact that diesels just don't sound as good as petrols.

8. They polute the atmosphere. The majority of photographic smog in big cities is caused by diesel vehicles.
Petrols pollute the atmosphere too. In fact if you are using more fuel you are polluting more. It is less noticeable at ground level though, and there isn't as much NOx or particulate matter in a petrol's fumes.

9. All in all they are thoroughly unpleasant and the person who invented them should have been strangled at birth.
Otto Diesel, and what a clever man he was :thumbs:

Mark my words, compression ignition will be the future of all engines :)

10. I voted for Petrol:lol:
So did I :lol:

He he, well answered mate. I must admit it was a bit tongue in cheek.
I liked the very last line:cheese:

Most recent technologial advances in engines have happened to Diesels. However with the latest generation of new technology petrols from Fiat just around the corner I wouldn't mind betting thet petrols won't be far behind diesels on the economy and performance fronts in the very near future.

Yes, FIATs cam-less engines with electro-hydraulic opening of valves, all timed via the ECU will be a marvel of engineering, but a bugger to fix if it goes wrong :lol:

Watch out for Mercedes new compression igntion turbo petrol though. Apparently it has a variable compression ratio, how that works I don't know!

I've had Head Gasket failure on diesels and so have a lot of people I know so would have to disagree with pud on that one. I'm not a mechanical engineer but would have thought that diesels are more prone to head gasket failure than petrol due to the higher compression ? :confused:

Cost of head gasket repair on the BX I had was astonishing, over £600 and that was back in the early 90's.

To answer the question though PETROL ! I'll admit to being a Petrolhead as it's a nice sounding expressive name, Dieselhead is quite another matter and sounds quite derogatory and vaguely green welly - ish !

First I've heard about HG on diesels. I know a lot of petrols prone to it, the Rover K Series being one, but I don't know a diesel that will suffer head gasket failure for no reason other than lack of maintenence. I thought diesels had a reputation for being much stronger engines than petrols?

There was a article in car mechanics a couple of months ago, and apparently Pug and Citroen diesels do suffer head gasket issues quite often. :rolleyes:

Hiya pud. All I can say is that back in the late eighties a lot of guys I know bought diesels as we were doing long distance commuting and diesel was the way to save a bit of money.

I started off with a 1.6 Escort, least said about that the better ! Then got a 1.9 BX, which was well maintained, and the head gasket failed taking with it the swirl pots and other sundry and expensive items. I also know of failures on the Pug 205, same engine as the BX, some Vauxhalls and on at least one Merc.

Obviously these are now old fashioned and dated engines but the high compression on modern diesels still remain so is it still a potential problem area ? :confused:

What I am pretty sure about is that once a Head Gasket does fail you're are in for repeat episodes and I for one would quickly sell any car that has had such a failure, been there too many times to want all the hassle again. The only exception to this was on a Ford 1600 Kent which I rapidly slung a new gasket in one Saturday afternoon and was perfect ever after. Everything else has caused me repeat problems, despite having all the machining done !:eek:

One advantage of having a tractor engine is - two weeks ago I was in the south of France and whilst I was going over the Millau Viaduct I experienced a total loss of power, black smoke billowing out of the exhaust and the dash board lit up like a Christmas tree with error codes (MCF, glow plug failure, water in fuel filter) . I thought ******** this looks terminal. I limped to the next service station about 5 K's and called the RAC. Within half an hour a Renault tractor dealer turned up with a tow truck and quickly diagnosed an EGR valve failure and took us to the Alfa dealer in Millau to get a replacement EGR valve. An hour later we were on our way and the old girl feels as good as new, in fact the engine feels and sound like it did when new and I have done almost 100,000 miles in her. The cost was just over 200 euros - a bargain I thought. The mechanic raved over the JTD engine stating it is pretty much bomb proof.

The JTD is definitely one of the 'good diesels'.. They are so rev happy, my old 2.4 10v revved like a petrol, in fact it was revvier than my brothers petrol Volvo! :lol:

Yoohooo - we are petrolheads after all. Look at that 2 to 1 in favour of petrol.

And it smells much nicer too :thumbs:

You mean the fuel smells nicer or the fumes smell nicer? I reckon the diesel fuel smells nicer myself like.. :hmm:

Petrol smells nicer and the fumes smell nicer. I hate getting diesel on my shoes when filling up and walking it into my car as it stays on the carpets for ages.

It also kills and injures lots of motorcyclists due to spillages from lorries onto the road. :tut:

That's lorries though, are you suggesting lorries should switch to petrol?

I would suggest they should maintain their tanks/lines better.

Petrol fumes are much more toxic, you don't want to go smelling those. It's also nastier if you get it on your skin.

Petrol is far dirtier and that is why the road fund licence (or whatever is it called) is going up astronomically for petrol - diesel has a historical problem with sooty deposits (there could be a joke there:) ) but is far friendlier to the environment as there is a lot less CO2, unless of course you go to those extreme lean burn engines.

I think the petrol heads may end up disappointed as the likely technology will result in petrol/diesel hybrids, such as Mercedes Diesotto and GM's Homogeneous Charge Compression Ignition engines
