Bad fuel in a BMW 750i xDrive? Diesel in a Petrol BMW?

ABOUT

Filling up with Diesel in a Petrol BMW is a usual problem. And its remedy varies according to various factors. In the event that you want to find out what it is advisable to do to fix it then please read on.
Here are the most important factors to keep in mind whenever figuring out whether or not to have a fuel drain:

1. Exactly how much Diesel have you put in to the BMW, bearing in mind that the fuel capacity of your BMW 750i xDrive is normally approximately 82 litres?
   1. A small quantity of Diesel, something like 4.1 litres of Diesel in a Petrol 750i xDrive will in most situations not really be a massive problem. Experience has shown us that anything less than 4.1 litres (which is 5% of the entire fuel tank capacity) is oftentimes able to be sufficiently diluted by means of entirely topping the rest of the tank with Petrol.
      It's highly rare to come across a vehicle going through difficulties due to lower than 5% wrong fuel contamination. Please remember it is infrequently found - certainly not impossible to encounter. You will discover a few motor vehicles that won't stand any level of contamination in the slightest.
   2. Anywhere between 4.1 and 8.2 litres of Diesel in the BMW (5 to 10%) is really a 50/50 scenario. Our working experience demonstrates that as many motorists get away with this as all those who break down. Whenever trying to decide whether to risk it and simply fill it up bear in mind that it is much like gambling your car on black - you have got a 50/50 chance of it working out.
   3. Anything in excess of 8.2 litres of Diesel in a Petrol 750i xDrive must straight away be drained out since your likelihood of succeeding with that amount of contamination is probably less than one in fifty - really big odds.
2. Put some Diesel in a Petrol BMW and drove it: Have you detected any performance difficulties as a result of putting the wrong fuel in your 750i xDrive? In that case, get it drained regardless of the amount of Diesel or even the contamination percentage. Continuing to drive driving a vehicle that is now starting to suffer from the consequences of wrong fuel contamination will typically result in increasing amounts of damage affecting your fuel system components.
3. Do you need peace of mind?
   Then get it drained. Regardless of contamination percentage, there is always some degree of danger caused by operating a Petrol motor on fuel contaminated with Diesel. Likely implications of driving a vehicle on the wrong fuel include the engine refusing to start, running lumpy, lack of power, degradation of the high-pressure pump, damaged or blocked injectors, etc. These are a few of the most common Diesel in Petrol signs or symptoms, and if you observe any of them stop and have it removed right away.
