BMW Fuel Drain

ABOUT

Filling Diesel in a Petrol BMW is a regular error. And exactly what you should do about it varies according to an assortment of things. In the event that you would like to find out what it is best to do about it then read on.
Listed here are the most important factors to think about when figuring out whether or not to have the car drained:

  1. How much Diesel have you put in the BMW, keeping in mind that the fuel tank capacity of the BMW 630i is normally around 70 litres?
    1. A tiny amount of Diesel, as little as 3.5 litres of Diesel in a Petrol 630i will in most situations not be a significant problem. Experience has shown us that anything under 3.5 litres (about 5% of the entire fuel tank) is very often able to be sufficiently diluted by entirely filling up the remainder of the tank with the appropriate fuel.
      It's quite uncommon to find a car or truck going through problems because of under 5% incorrect fuel contamination. Be aware that it is very infrequently found - not impossible to find. There are actually certain cars that don't endure any level of fuel contamination whatsoever.
    2. Somewhere between 3.5 and 7 litres of Diesel in the BMW (5 to 10%) is a 50/50 scenario. Our experience has proven that as many people get away with this as all those who break down. When you are trying to decide whether or not to chance it and simply top it up bear in mind that it is exactly like betting it all on black - you will have a 50/50 chance of it working.
    3. Anything in excess of 7 litres of Diesel in a Petrol 630i should as soon as possible be drained since your likelihood of succeeding with this amount of contamination is in all likelihood below one in fifty - genuinely long odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you observed any performance troubles as a result of putting the bad fuel in the 630i? If that's the case, have it removed regardless of the volume of Diesel or the contamination ratio. Continuing to run driving a car that is already starting to suffer from the consequences of wrong fuel contamination will just result in more damage being caused to the fuel system components.
  3. Are you interested in peace of mind?
    Then get it drained. Regardless of the contamination ratio, there is invariably a certain level of risk linked with operating a Petrol vehicle on Petrol contaminated with the incorrect fuel. Likely implications of driving on the wrong fuel normally include the motor refusing to start, running unevenly, loss of power, wearing of the high-pressure pump, worn or bunged injectors, etc. These are some of the most typical Diesel in Petrol symptoms, and if you recognise any of them stop and get it drained asap.

Stay away from having any general so-and-so to attend your vehicle. We are BMW specialists and have the skills and practical experience needed to ensure you get back on the road with a minimum of hassle or worry.

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.
