BMW Fuel Drain


Filling up with Diesel in a Petrol BMW is a well-known mistake to make. And its solution hinges on various factors. In the event that you would like to find out what you must do to sort it out then keep reading.
Listed here are the main variables to to consider when figuring out whether to have a fuel drain:

  1. How much Diesel did you put in to the BMW, bearing in mind that the fuel tank capacity of your BMW Z8 is most likely about 73 litres?
    1. A tiny amount of Diesel, less than 3.65 litres of Diesel in a Petrol Z8 will quite often not really be a huge problem. Experience has demonstrated to us that anything under 3.65 litres (roughly 5% of the fuel tank capacity) is sometimes capable of being adequately diluted through wholly topping the rest of the tank with the right fuel.
      It is extremely unusual to encounter a car or truck suffering from difficulties because of under 5% incorrect fuel contamination. Bear in mind that it's uncommon - not impossible to find. There are certain vehicles that won't endure any level of contamination at all.
    2. Between 3.65 and 7.3 litres of Diesel in the BMW (from 5 to 10%) is really a 50/50 condition. Our working experience demonstrates that as many drivers get away with this as all those who don't. When deciding upon whether or not to risk it and just simply fill it up bear in mind that it is much like wagering everything on black - you've got a 50/50 possibility of it being ok.
    3. Anything above 7.3 litres of Diesel in your Petrol Z8 should really straightaway be removed as your probability of driving with that level of contamination is in all likelihood lower than one in fifty - extremely big odds.
  2. Put some Diesel in a Petrol BMW and drove it: Have you spotted any performance issues since putting the incorrect fuel in the Z8? If that's the case, get it emptied irrespective of the amount of Diesel or even the contamination percentage. Proceeding to run driving a car that is currently beginning to suffer from the consequences of fuel contamination will probably typically result in more and more damage affecting the fuel system.
  3. Would you like peace of mind?
    Simply get it emptied. Regardless of the contamination ratio, there is invariably some degree of risk associated with running a Petrol vehicle on fuel contaminated with Diesel. Possible results of driving on the incorrect fuel normally include the engine refusing to start, running unevenly, loss of power, degradation of the high-pressure pump, worn or bunged injectors, and so on. These are several of the most common Diesel in Petrol symptoms, and if you notice any of them stop and get it removed immediately.

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.
