BMW Fuel Drain

ABOUT

Filling up with Diesel in a Petrol BMW is a common error. And its remedy is based on a variety of factors. In the event that you would like to find out what you have to do about this then keep reading.
Listed here are the most crucial factors to to consider whenever deciding whether to get the car drained:

  1. How much Diesel have you put in the BMW, bearing in mind that the fuel capacity of your BMW 550i is in most cases about 70 litres?
    1. Hardly any Diesel, something like 3.5 litres of Diesel in a Petrol 550i will typically not necessarily be a significant problem. Experience has demonstrated to us that an amount less than 3.5 litres (5% of the whole fuel tank volume) is generally capable of being completely diluted through entirely topping the remainder of the tank with Petrol.
      It's very rare to find a car or truck having issues with less than 5% wrong fuel contamination. Keep in mind it is very unusual - not impossible to encounter. You will discover some cars that don't stand any quantity of fuel contamination at all.
    2. Somewhere between 3.5 and 7 litres of Diesel in the BMW (5 to 10%) is really a 50/50 scenario. Our working experience demonstrates that as many people get away with this as those who break down. Any time you are deciding whether to chance it and simply fill it up consider that it is much like betting it all on black - you have got a 50/50 possibility of it being ok.
    3. Anything in excess of 7 litres of Diesel in a Petrol 550i ought to straightaway be drained seeing as your probability of succeeding with this amount of contamination is almost certainly below one in fifty - definitely big odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you noted any performance issues after putting the incorrect fuel in your 550i? If that's the case, get it emptied irrespective of the amount of Diesel or the contamination percentage. Continually driving a vehicle that is beginning to suffer the consequences of fuel contamination can just lead to progressively more harm affecting the fuel system parts.
  3. Would you like peace of mind?
    In that case get it drained. Regardless of contamination ratio, there is always some extent of threat in connection with driving a Petrol motor on Petrol contaminated with Diesel. Likely results of driving on the wrong fuel can include the engine not starting, running unevenly, loss of power, degradation of the high-pressure pump, worn or bunged injectors, and the like. These are a few of the commonest Diesel in Petrol warning signs, and in the event that you notice any of them then cease driving and get it removed asap.
