BMW Fuel Drain


Putting Diesel in a Petrol BMW is a usual problem. And exactly what you have to do about it will depend on an assortment of factors. If perhaps you want to find out what you ought to do about it then keep reading.
Right here are the main factors to to consider when figuring out whether or not to get your car drained:

  1. What amount of Diesel did you put in the BMW, considering that the fuel tank capacity of your BMW ActiveHybrid 7L is most likely roughly 82 litres?
    1. Hardly any Diesel, something like 4.1 litres of Diesel in a Petrol ActiveHybrid 7L will in most situations not be a big problem. Experience has taught us that quantities less than 4.1 litres (approximately 5% of the total fuel tank volume) is generally capable of being completely diluted simply by wholly topping the tank with Petrol.
      It's highly uncommon to come across a car or truck going through issues because of lower than 5% wrong fuel contamination. Keep in mind that it is uncommon - in no way impossible to find. There are actually a number of cars that will not endure any level of fuel contamination at all.
    2. Between 4.1 and 8.2 litres of Diesel in the BMW (from 5 to 10%) is more of a 50/50 condition. Our working experience has demonstrated that as many motorists get away with it as all those who don't. Whenever you are trying to decide whether to risk it and just fill it up consider that it is exactly like gambling your car on black - you have a 50/50 chance of it working out.
    3. Anything over 8.2 litres of Diesel in your Petrol ActiveHybrid 7L ought to as soon as possible be removed as your likelihood of succeeding with this level of contamination is certainly less than one in fifty - genuinely long odds.
  2. Put some Diesel in a Petrol BMW and drove it: Have you observed any performance difficulties since putting the bad fuel in your ActiveHybrid 7L? If you have, get it emptied regardless of the amount of Diesel or the contamination percentage. Still driving an automobile that is now starting to suffer the consequences of wrong fuel contamination will definitely cause progressively more harm being done to your fuel system parts.
  3. Would you like peace of mind?
    In that case get it emptied. Regardless of the contamination percentage, there is invariably some degree of danger affiliated with driving a Petrol vehicle on Petrol contaminated with the wrong fuel. Probable results of driving on the incorrect fuel can include the motor not starting, running lumpy, loss of power, degradation of the high-pressure pump, worn or clogged injectors, and so forth. These are several of the most frequently seen Diesel in Petrol symptoms, and should you detect any of them then stop driving and get it drained asap.

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.
