Having driven petrol car for 20yrs, i bought new high performan ce diesil vectra.being a total twat i filled with petrol instead od diesil, run it for 3/4 mile to my home before engine started making noises and died on me!!! how serious is this and can engine be salvaged??? ( car brand new)

Diesel is an oil so it lubricates the injector pump and the injectors , petrol is not a lubricant so it can damage them but if you have only driven a short distance i would say there is no damage . the reason the car cut out is simply because it is a compression igniton ( c.i ) engine ( diesel ) compared to a spark ignition ( s.i ) engine ( petrol ) and petrol needs the spark to ignite and diesel engines dont have them therefore the petrol will not combust properly and the engine will not run. its still not a cheap job having the tank removed and drained and all the fuel lines purged but its a lot cheaper than replacing the injector pump etc . also a lot of the replies said about the head being damaged , thats nonsense because a diesel engine is built stronger because it has to withstand higher compression ratios than petrol engines. its not as bad as putting diesel in a petrol car cos diesel will eat the fuel pipes and rubber seals in the petrol injection system , expensive. learn from this mistake and remember next time , black nozzle lol
