petrol in diesel?

dubtom

After a week of using a hire car on petrol, I put 99 cent worth into my diesel car today before I realised.Phoned a friend and he recommended filling up, cost me 74 quid. Although the car is running fine now I'm a little worried. Did I read here that petrol in a diesel was a big nono, and diesel in a petrol was ok, or was it the other way around.

Can't imagine there being any problems sure 99cents is only a teaspoon full of petrol now. It would just be mixed with the petrol and should be fine. What car was it? Most petrol cars won't let a diesel pump fit into the tank?

0.099 cents may be a teaspoon full, 99 cents is closer to a litre.;) That said, I don't think a small amount of petrol in a diesel car should do any harm. Diesel in a petrol car is indeed a big no-no, though.

Less than a litre of Diesel in tank of petrol is nothing to worry about nor is the other way round.

It's the other way around. Petrol cars won't let a diesel pump fit into them.

Nothing at all to worry about -especially as you filled it up with diesel afterwards. Drive on...............

Anyone ever try putting a litre of oil into the fuel tank?

One of the tricks to pass the DOE, is to put some petrol into a diesel....it lowers the smoke emissions!!

I put 3 liters of petrol into 40 diesel.....not even a tiny puff of smoke!!!

according to the audi owners manual you can mix diesel and petrol 3 : 1 in the event of a sudden cold snap to prevent icing of the diesel so i would'nt worry about less than a gallon of petrol in almost a full tank of diesel. in fact it will help to clean the carbon out of your system.

I have on occasion put 2 stroke oil in with my petrol to lubricate the injection pump, a lot of folk in the states do it too if they are laying their cars up for long periods !

I've heard about adding a small amount of petrol to a diesel fill being good for older diesel engines, but I've also heard that its a big no-no for modern common rail diesels. Is this true?

If you regularly drive in -15degress celcius it will help stop waxing, although not as well as a proper additive. It might also help a car with poor compression to start. Other than that though I can't see how it would help, but might only cause premature wear of the diesel pump.

Yes. The OP is fine, but you wouldn't want to be doing it on purpose.

Thats what I'd said, I misread the op
