BMW Fuel Drain

ABOUT

Putting Diesel in a Petrol BMW is a well-known error. And exactly what you need to do about it is based on an assortment of things. In the event that you would like to find out what you need to do about this then continue reading.
Here are the most crucial variables to keep in mind when determining whether or not to have a fuel drain:

  1. What level of Diesel did you put into the BMW, taking into account that the fuel tank capacity of the BMW 750Li is normally roughly 88 litres?
    1. A small amount of Diesel, something like 4.4 litres of Diesel in a Petrol 750Li will normally not be a big problem. Experience has taught us that quantities less than 4.4 litres (about 5% of the whole fuel tank capacity) is very often able to be completely diluted simply by entirely topping the tank with the correct fuel.
      It is very uncommon to encounter a car or truck having issues because of lower than 5% incorrect fuel contamination. Please remember it is uncommon - certainly not impossible to find. You can get some automobiles that will not stand any amount of contamination at all.
    2. In between 4.4 and 8.8 litres of Diesel in the BMW (5 to 10%) is more of a 50/50 condition. Our working experience has revealed that as many people get away with this as those who break down. Whenever you are deciding on whether or not to risk it and basically top it up bear in mind that it is the same as betting your car on black - you've got a 50/50 chance of it being ok.
    3. Anything in excess of 8.8 litres of Diesel in your Petrol 750Li really should straightaway be drained as your probability of getting away with that quantity of contamination is very likely below one in fifty - really long odds.
  2. Put some Diesel in a Petrol BMW and drove it: Have you spotted any performance problems as a result of putting the wrong fuel in the 750Li? If you have, get it removed regardless of the quantity of Diesel or even the contamination percentage. Continually driving a car that is already beginning to suffer from the consequences of fuel contamination will typically cause more harm being done to the fuel system parts.
  3. Do you want peace of mind?
    Then get it emptied. Regardless of contamination percentage, there is always some extent of risk affiliated with driving a Petrol engine on Petrol contaminated with Diesel. Possible outcomes of driving on the wrong fuel include the motor refusing to start, running unevenly, decrease in power, wearing of the high-pressure pump, worn out or clogged injectors, and so forth. These are some of the most common Diesel in Petrol symptoms, and if you recognise any of them cease driving and have it drained right away.
