BMW Fuel Drain

ABOUT

Filling up with Diesel in a Petrol BMW is a regularly occurring mistake to make. And its remedy is dependent upon various things. In the event that you want to know what you ought to do to fix it then please read on.
Listed here are the most important factors to keep in mind whenever determining whether or not to have your car drained:

  1. What level of Diesel have you put into the BMW, taking into consideration that the fuel capacity of your BMW 535i is most likely approximately 70 litres?
    1. A modest quantity of Diesel, less than 3.5 litres of Diesel in a Petrol 535i will quite often not necessarily be a massive problem. Experience has demonstrated to us that quantities less than 3.5 litres (which is almost 5% of the entire fuel tank) is oftentimes capable of being sufficiently diluted by means of entirely topping up the tank with Petrol.
      It is quite uncommon to come across a motor vehicle suffering from problems with below 5% wrong fuel contamination. Bear in mind that it is infrequent - definitely not impossible to encounter. You will discover a number of motor vehicles that don't endure any amount of contamination in the slightest.
    2. Anywhere between 3.5 and 7 litres of Diesel in the BMW (from 5 to 10%) is a 50/50 situation. Our working experience has revealed that as many drivers get away with this as those people who don't. When you are deciding upon whether or not to risk it and just simply top it up recognise that it is the same as wagering it all on black - you've got a 50/50 chance of it working out.
    3. Anything above 7 litres of Diesel in your Petrol 535i ought to straight away be removed since your probability of getting away with that amount of contamination is certainly lower than one in 50 - extremely big odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you seen any kind of performance issues as a result of putting the bad fuel in the 535i? If that's the case, have it emptied irrespective of the volume of Diesel or even the contamination percentage. Continually running a car that is already beginning to suffer from the effects of wrong fuel contamination will definitely be responsible for even more harm being done to your fuel system parts.
  3. Would you like peace of mind?
    Then get it removed. No matter the contamination percentage, there is always some degree of risk associated with operating a Petrol motor on Petrol contaminated with Diesel. Possible outcomes of driving on the wrong fuel include things like the motor not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn or bunged injectors, and so on. These are some of the most typical Diesel in Petrol signs or symptoms, and in the event that you notice 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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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.
