Um... it takes 300ºC to extract diesel, but 150ºC to extract petrol from crude oil- how does that make petrol harder to produce than diesel?

I am sorry, but i don't understand what you mean from the Kitty thing onwards. Back to English class i guess
They are for the main part natural gasses. The amount caused by humans is tiny in comparison.Read this.
See other post.I know diesel comes lower in the refinery chain than petrol, but since when was aeroplane fuel (the lowest) cleaner than diesel?
What one finds a disadvantage, the other finds an advantage. Doing less revs is much more comfortable to drive for example The maintenance on the particle filters is usually about every 150.000 km's AFAIK. It's a miracle if your exhaust survives that in the first place..Don't patronise me. I know fully well how a particulate filter works, I've been looking into getting a diesel car for quite some time to try and work out the advtanges. As far as I can see, you need to maintain a particulate filter more than a catalytic converter (presumably to clean out all the crap produced by a diesel engine). I do appreciate diesels, but I will not accept that they are 'cleaner' than petrol engines, because they have different ways of polluting. They cannot be compared like-for-like- petrols rev high, with more efficient power outputs (probably because of the more refined fuel). Diesels seem to need a turbo to be acceptable- have you ever looked at the power figure for the 1.7SDI diesel engine? It's nowhere near the natune output of a 1.7 petrol engine, such as the Yamaha 1.7 in the Ford Puma. I know both are tuned differently, but the disadvantage in the SDI is obvious.
Kitty is my 206. She's very touchy. You still haven't addressed your own comparison of the 205 GTi to the base model Peugeots.
Yes, and so are many of the gases produced by petrols- I heard on the radio that all oil-powered machines produce less than 12% of the world's greenhouse gases. So yeah... next...
Right back at ya!
Er... my parents are driving a 1.4 Honda Civic that still has its original clutch and exhaust after just about 90,000 miles- that's 144,000km
And if you wouldn't mind addressing the efficiency issues I've presented...
I think you need to change these numbers mate
Petrol is a lot purer than diesel. In the distilling columns filled with crude oil diesel is taken at the 3rd or 4th "dish" or extraction point. Petrol is the 2nd from the top. There are about 12-15 in each column. Petrol needs multiple columns to end up as the correct Octane number. Diesel only needs one stage of further refining.
Why I know all this you must be thinking by now ? Two reasons. My graddad was Chief Inspector at the Shell refinery nearby and taught me a lot about it in my childhood years. And now my best friend does a education specialised in these things. I hear quite some things about it
because the natural yield of petrol from an average API crude oil is far less than the production of middle distillates, like gasoil and kerosene. To produce more petrol a secondary technique, (cracking) is required...

IWAARS6 and drakkie, go and find yoursleves an Alfa Romeo GTV6 and stop complaining about which fuel is destiled hotter or what do particulate filters do...

Visca Catalunya!
205GTi lacked pizzaz!? Are you crazy, it looked fantastic! especially in metalic blue! My Dad's sister absolutely adored her 1.9. and I'm pretty sure my Dad's brother loved his. Don't know what Dan's Dad thought of his... He flipped his mid corner...Huh? I put my foot to the floor in 3rd at 3,500rpm and not alot happened, I would've thought the powerband was 4,000rpm+ that's about what it was in our old 205 I think, same engine is it not?
And Ruim, do you mean the trumpet like tailpipe where it suddenly gets really open as it exits through the bumper? Noticed that on the Head of English's 306Diesel at school.

Actually I have been looking at some 75 V6's. The insurance of 4x what i pay now and the state of the cars in my budget range put me off of it.
What ? You got to agree on these points Offcourse you'll learn petrol after a while, I rarely stall it now (more wheelspin off the light )... But diesel is something I miss in traffic jams, which I encounter atleast once every time I drive.
