Petrol In Diesel Car

[kenks]

Hello all im in need of some help hopefully with good news,iv just put petrol in my emina diesel and drove about two miles before car started spluttering.iv managed to drain the petrol and get car running but now the oil is pissin out of the dipstick,it stops if i take the filler cap off but as soon as i put it back on it starts pissin out again.HELP PLEASE WITH ANY INFO good or bad thanks Kenks

Hi Kenks and welcome.

when you say you take the cap off do you mean petrol cap or oil filler cap.

If you do mean the oil filler cap then the engine breather is not handling the crankcase pressure,its either the breather blocked or too much crankcase pressure possibly due to piston/rings/bores damage running on petrol,but i would be surprised if this has happened.

i dont know what model a Emina is but if you go on the forums (see top of page)and find one for your car you may be given advice there.

If you have started your engine then the jets will need to be cleaned and the tank and pipes cleaned. Better than putting diesel in a petrol anyway.

Oil level too high now ?(with bypass petrol )

Somehow I don't think so. As diesels work on the compression ignition principle petrol will do a helluva lot more harm to a diesel engine than putting diesel into a petrol.

My brother-in-law put £40 worth of petrol in his diesel Mondeo and had no problems. He just topped the tank up with derv and all was okay! But the best thing to do in my view is to drain the tank and clean the fuel lines and replace the fuel filter...

HI James, you are correct petrol in a diesel engine can ruin some injection systems.

when i brought my first diesel car back in 1986 a vw jetta 1.6 td and there was few diesel cars about then and even fewer turbo ones the handbook approved putting 25% petrol in the tank in the winter months to stop waxing,there were no anti waxing additives in the fuel as there are now.

the rotaty fuel pump system was for more robust than the modern systems used these days and so was the engines too.nearly bullet proof even with much higher compression ratios.

putting diseel in a prtrol motor is no problem once system is cleared out.

Hi Mate.

£40 pounds worth at todays prices,why thats only a dribble.

It's not just the injection system but the ignition is the problem. Modern diesel engines have injection pressures of up to 20,000 psi - imagine how petrol will behave if injected into an engine and ignited by compression. A holed or cracked piston is the risk.

I dont think you wll find that petrol can be ignitred by compression heat as diesel can.let alone run long enough to hole a piston.

diesel as well as being a fuel, it also lubricates parts of the injection set up.

damage is done by lack of this lubricant when petrol passes through the system.

it does not have to run for long to damage the fine tolerances in a diesel injection system.

It depends when adding petrol to the diesel,how much diesel is already in the the tank.i mean what is the percentage of the diesel is petrol.which is critical if your lucky to get away without any damage.

thanks all,i got petrol flushed out and car running again and now theres oil pouring out of dipstick :crybaby:

[dervdave]

now theres oil pouring out of dipstick

You said that in your first post and my answer was `Oil level too high now ?(with bypass petrol )`

Is the oil petrol contaminated ?

Lol... You're to right an all my mate.
