Today I have fuelled for the first time instead of diesel petrol. However, only a very small amount +/- 50ml (for a whole 7 cents). I then filled my diesel tank with 51litres full and drove well 40km home. Motor is a commonrail Opel Z17DTL. Has all this followed late or does such a small amount not matter at all? So at least on the journey home there were no differences in the suit or in the engine run.
