Incorrect fuel in a BMW 520d? Petrol in a Diesel BMW?

ABOUT

Filling up with Petrol in a Diesel BMW is a regularly occurring error. And exactly what you should do about it depends on several different factors. If perhaps you want to know what to do about it then read on.
Let us discuss the key variables to consider when making a decision whether to have a fuel drain:

1. How much Petrol have you put into the BMW, taking into account that the fuel tank capacity of your BMW 520d is normally around 70 litres?
   1. A small amount of Petrol, less than 3.5 litres of Petrol in a Diesel 520d will more often than not not be a huge problem. Experience has demonstrated to us that an amount under 3.5 litres (which is approximately 5% of the overall fuel tank volume) is frequently capable of being completely diluted simply by completely filling the remainder of the tank with Diesel.
      It is highly uncommon to come across a vehicle having issues due to under 5% wrong fuel contamination. Keep in mind that it is very infrequently found - in no way impossible to find. There are actually a number of vehicles that don't stand any degree of fuel contamination at all.
   2. Anywhere between 3.5 and 7 litres of Petrol in the BMW (from 5 to 10%) is more of a 50/50 scenario. Our working experience has shown that as many motorists get away with this as those who break down. Any time you're deciding upon whether or not to chance it and basically top it up recognise that it is exactly like wagering your car on black - you have got a 50/50 possibility of it being ok.
   3. Anything in excess of 7 litres of Petrol in a Diesel 520d should really immediately be drained since your likelihood of succeeding with this level of contamination is undoubtedly lower than one in fifty - seriously big odds.
2. Put Petrol in a Diesel BMW and drove it: Have you noted any kind of performance issues as a result of putting the bad fuel in the 520d? If you have, have it drained no matter the amount of Petrol or the contamination percentage. Still running a vehicle that is starting to suffer from the effect of wrong fuel contamination will probably only cause increasing amounts of harm affecting your fuel system.
3. Do you want security?
   Then simply just get it removed. Regardless of contamination ratio, there is inevitably a certain level of threat connected with driving a Diesel vehicle on Diesel contaminated with Petrol. Possible consequences of driving a vehicle on the incorrect fuel include things like the motor refusing to start, running lumpy, lack of power, wearing of the high-pressure pump, worn or blocked injectors, and the like. These are several of the most common Petrol in Diesel warning signs, and should you recognise any of them stop and get it drained as soon as possible.
