BMW Fuel Drain


Filling up with Diesel in a Petrol BMW is a regular error. And its solution is based on several different factors. Assuming you want to know what it is best to do about it then continue reading.
Listed below are the main factors to consider when making a decision whether to get a fuel drain:

  1. How much Diesel did you put into the BMW, taking into consideration that the fuel tank capacity of the BMW 528i Touring is in most cases about 70 litres?
    1. A small quantity of Diesel, less than 3.5 litres of Diesel in a Petrol 528i Touring will quite often not really be a significant problem. Experience has taught us that quantities less than 3.5 litres (about 5% of the entire fuel tank capacity) is frequently capable of being completely diluted through totally topping up the rest of the tank with Petrol.
      It's highly unusual to encounter a motor vehicle experiencing issues due to below 5% wrong fuel contamination. Keep in mind that it is very infrequent - certainly not impossible to encounter. You will discover a number of vehicles that will not endure any amount of contamination in the slightest.
    2. Somewhere between 3.5 and 7 litres of Diesel in the BMW (from 5 to 10%) is a 50/50 situation. Our expertise has proven that as many motorists get away with this as all those who don't. When trying to decide whether or not to risk it and basically top it up remember that it is the same as wagering your car on black - you have got a 50/50 possibility of it working out.
    3. Anything above 7 litres of Diesel in your Petrol 528i Touring really should straight away be removed since your likelihood of getting away with this quantity of contamination is certainly less than one in fifty - definitely huge odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you seen any performance issues ever since putting the bad fuel in your 528i Touring? If you have, have it drained no matter the quantity of Diesel or even the contamination percentage. Proceeding to run running an automobile that is already beginning to suffer the effect of fuel contamination will probably definitely result in more and more damage being done to the fuel system.
  3. Do you want security?
    In that case get it removed. Regardless of contamination percentage, there is inevitably a certain level of danger caused by driving a Petrol engine on Petrol contaminated with Diesel. Likely final outcomes of driving a vehicle on the wrong fuel normally include the engine refusing to start, running unevenly, losing power, degradation of the high-pressure pump, worn or blocked injectors, and so forth. These are several of the most frequently seen Diesel in Petrol symptoms, and in the event that you detect any of them stop driving and have it removed 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.
