BMW Fuel Drain

ABOUT

Filling up with Diesel in a Petrol BMW is a very common mistake. And what you should do about it depends upon an assortment of things. In the event that you want to know what you should do to fix it then continue reading.
Here are the key factors to be aware of whenever choosing whether to get the car drained:

  1. What level of Diesel have you put into the BMW, keeping in mind that the fuel tank capacity of the BMW 118i is most likely around 53 litres?
    1. A tiny quantity of Diesel, as little as 2.65 litres of Diesel in a Petrol 118i will typically not really be a significant problem. Experience has shown us that quantities less than 2.65 litres (which is close to 5% of the fuel tank) is sometimes capable of being completely diluted by means of wholly filling the remainder of the tank with Petrol.
      It's very uncommon to find a car suffering from difficulties due to less than 5% incorrect fuel contamination. Do not forget that it is very infrequently found - certainly not impossible to find. There are actually some cars that don't endure any quantity of fuel contamination whatsoever.
    2. Anywhere between 2.65 and 5.3 litres of Diesel in the BMW (5 to 10%) is a 50/50 condition. Our experience has revealed that as many motorists get away with this as all those who don't. When you are deciding on whether or not to risk it and just fill it up remember that it is the same as wagering your car on black - you have got a 50/50 possibility of it being ok.
    3. Anything in excess of 5.3 litres of Diesel in a Petrol 118i really should straightaway be drained seeing that your probability of getting away with this level of contamination is certainly below one in fifty - seriously huge odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you noticed any performance troubles ever since putting the bad fuel in your 118i? If that's the case, get it drained irrespective of the quantity of Diesel or even the contamination percentage. Still running an automobile that is now beginning to suffer the consequences of wrong fuel contamination can definitely end up in even more harm affecting your fuel system components.
  3. Are you looking for assurance?
    You should get it removed. Regardless of contamination ratio, there is inevitably a certain level of threat connected with operating a Petrol motor on fuel contaminated with Diesel. Probable final outcomes of driving on the wrong fuel normally include the engine refusing to start, running lumpy, lack of power, degradation of the high-pressure pump, worn out or blocked injectors, and so forth. These are a few of the most common Diesel in Petrol signs and symptoms, and if you notice any of them stop and have it removed right away.

Putting Super Unleaded, or Shell V-Power, BP Ultimate Unleaded, etc, will have the exact same effect as putting regular unleaded petrol in your diesel car and will need to be drained out and flushed.

Will getting you to do a fuel drain void my warranty?

No! The EU Block Exemption Regulations clearly state that "the work can be carried out by as long as that garage uses manufacturer approved parts and correctly follows the manufacturer's service schedule."

Can I top it up with Petrol and add some 2-stroke oil?

This might work on some vehicles in some cases, but in the majority on instances it won't and you risk damaging the Lambda sensors as well as fuel pump and injectors, just as a regular misfuel.
