BMW Fuel Drain


Filling Diesel in a Petrol BMW is a very common error. And its solution depends upon a number of things. In case you want to find out what to do to sort it out then continue reading.
Listed here the most crucial variables to be aware of whenever deciding on whether to have a fuel drain:

  1. What amount of Diesel have you put in the BMW, taking into account that the fuel capacity of your BMW 114i is probably roughly 52 litres?
    1. Hardly any Diesel, as little as 2.6 litres of Diesel in a Petrol 114i will generally not be a big problem. Experience has shown us that quantities less than 2.6 litres (which is roughly 5% of the fuel tank volume) is usually able to be sufficiently diluted simply by completely filling the rest of the tank with the correct fuel.
      It's highly rare to find a car having problems with lower than 5% incorrect fuel contamination. Keep in mind that it is unusual - not impossible to encounter. You will discover some automobiles that will not endure any amount of fuel contamination in the slightest.
    2. Somewhere between 2.6 and 5.2 litres of Diesel in the BMW (from 5 to 10%) is really a 50/50 situation. Our expertise has proven that as many drivers get away with this as all those who break down. Any time you're deciding upon whether or not to chance it and just simply fill it up consider that it is much like gambling your car on black - you've got a 50/50 possibility of it being ok.
    3. Anything in excess of 5.2 litres of Diesel in your Petrol 114i should straight away be drained out as your probability of succeeding with this amount of contamination is more than likely below one in fifty - seriously big odds.
  2. Put some Diesel in a Petrol BMW and drove it: Have you detected any performance troubles ever since putting the incorrect fuel in the 114i? If that's the case, get it emptied no matter the amount of Diesel or even the contamination ratio. Proceeding to drive running a vehicle that is already starting to suffer from the effect of wrong fuel contamination will probably typically end up in increasing amounts of harm affecting the fuel system parts.
  3. Do you need peace of mind?
    In that case get it emptied. Regardless of the contamination ratio, there is inevitably a certain level of threat connected with operating a Petrol vehicle on Petrol contaminated with Diesel. Possible outcomes of driving a car on the incorrect fuel include things like the engine refusing to start, running unevenly, losing power, wearing of the high-pressure pump, worn out or bunged injectors, etc. These are several of the commonest Diesel in Petrol warning signs, and should you observe any of them stop and get it drained as soon as possible.

Diesel in Petrol Questions

When someone has put Diesel in a Petrol car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Diesel in a Petrol car and drove it. What do I do?


Turn off the car as soon as possible and call us. Continuing to run a vehicle on the wrong fuel can potentially damage it. We will be able to give you advice and assistance based on your circumstances

Will driving a Petrol car on Diesel cause damage to it?


It can. However, if the problem is caught and remedied quickly the risks will be minimal. Of the 1,500 vehicles we attend every month, less than 0.5% have suffered and substantial damage requiring parts replacement.

How much Diesel can I get away with in a Petrol car?


The safe answer is none. However you might be able to get away with a very low contamination ratio. That being said, we always highly recommend draining anything over a 5% contamination ratio asap.

I know about petrol in diesel, but what about Super Unleaded?


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.
