    I failed the doe test this morning on emissions and i was chattin to a guy who told me that if i put about 3 litres of petrol into a full tank of diesel that it will clean out the engine. Now is this goin to cause my engine to fail or not has anyone done this before

    Yep i put €1 worth of petrol into my car before NCT and had been using smoke reducer/injection cleaner in the tank before that, pre NCT fuel additive i got in the motor factors.
    Personally my car was way below any high levels and my car never smokes, so i wont be putting petrol in it again unless it actually fails the NCT first.
    But a small amount of petrol is fine in your engine, but id really only put very little as petrol doesnt have lubricant so it could distroy your engine if too much is put in.
    Others could maybe better advise, but id say €2-€5 to a full tank.
    Ive also heard of driving at high revs before hand, blow the cobwebs out of the exhaust.

    Considering how often it is recommended here to add petrol to a diesel tank to clean it out maybe this should be a sticky.

    Petrol contaminated diesel can and very likely will damage a modern common rail diesel injection system. Serious damage can occur in a short time and is very expensive to repair.



    Heres a few links for anyone who is interested.
