What to do if you put petrol into a diesel car?

Answer 1

I very recently did this so have done a lot of research - my car is still outside waiting for me to put it right. It all seems to depend on who you ask. Many people will tell you that you need to drain the whole system etc etc. However, I have asked a few mechanics and it all depends upon how much petrol you have added. I am told that in cold countries drivers add petrol to diesel to prevent waxing - as long as it is less than 10% petrol to diesel it is OK. I put 7 litres of petrol in a diesel engine. The AA told me I had to have it drained completely, flushed and bled. I could not afford all this so topped it up with diesel and drove it home (about 2 K). Local mechanics told me to dilute it as much as pos and drive it but keep diluting it. I am not taking any chances. i am going to syphon off as much of the petrol and diesel mix as possible and fill it with pure diesel thereby avoiding the very large garage fees involved in drainage, flushing and bleeding. If people add a 10% mix i am sure I can get it down to less than this and it will be OK. I am sorry this is not a more informed answer but after asking a lot of people it is the best I can come up with. Best of luck.

Answer 2

After you have put diesel in tank,you can use starting fluid. Use only enough to start engine. This should draw diesel into motor. Again do not use to much. Squirt about 3-4 seconds into air filter intake. Turn on key and wait for (wait to start ) light to go off. If you have a primer pump try that first.

Answer 3

Drain it out immediately, DO NOT run the engine.
