how much diesel have you put in? and i wouldnt have thought you could do more damage in a petrol engine that if you put petrol in a diesel?
first thing i would do is call the rac/aa if your in one of those,if not you have got to get the tank drained (this is if you have filled it to the top) if you have only put a tenners worth in, fill it up with petrol? it may run sh1te for a while but it will sort itself out?
alternativly, you could take it to a garage and let them tell you what you really dont want to hear and spend loads of money letting them sort it?
er.. diesel in a petrol engine is BAD<\b> news. Diesel is more explosive than petrol and will blow your engine apart!
You need to get your tank drained and filled with petrol.
If there's only a small proportion of diesel mixed with the petrol, you should get away without any serious damage.
Diesel more explosive than petrol? I find that hard to believe. I know you can throw lighted matches into a tin of diesel and they go out. I wouldn't like to try that with petrol.
I can see what ugly bob is saying - diesel is more powerful but only due to the higher compression ratio
within a diesel engine - a petrol engine generally has a lower compression ratio.
As for putting diesel in a petrol car - i would have thought that would choke/ruin the catalytic converter.
