BMW Fuel Drain

ABOUT

Filling up with Petrol in a Diesel BMW is a regularly occurring mistake to make. And its solution depends upon a few factors. In the event that you want to find out what you ought to do about this then read on.
Let us discuss the main variables to to consider whenever choosing whether or not to get your car drained:

  1. How much Petrol did you put into the BMW, taking into consideration that the fuel tank capacity of the BMW 725tds is usually roughly 85 litres?
    1. Hardly any Petrol, as little as 4.25 litres of Petrol in a Diesel 725tds will most of the time not necessarily be a big problem. Experience has demonstrated to us that an amount under 4.25 litres (approximately 5% of the overall fuel tank capacity) is sometimes capable of being sufficiently diluted simply by totally topping up the tank with Diesel.
      It's very uncommon to encounter a car experiencing issues because of lower than 5% wrong fuel contamination. Please remember it's uncommon - definitely not impossible to find. You will discover certain motor vehicles that won't endure any amount of fuel contamination whatsoever.
    2. Anywhere between 4.25 and 8.5 litres of Petrol in the BMW (from 5 to 10%) is a 50/50 situation. Our practical experience has demonstrated that as many drivers get away with this as those who don't. Whenever you are deciding upon whether to chance it and just fill it up remember that it is just like wagering it all on black - you have got a 50/50 chance of it working.
    3. Anything over 8.5 litres of Petrol in a Diesel 725tds must straightaway be drained out because your probability of succeeding with that amount of contamination is very likely less than one in 50 - extremely long odds.
  2. Put Petrol in a Diesel BMW and drove it: Have you seen any kind of performance troubles ever since putting the wrong fuel in the 725tds? If you have, have it removed irrespective of the volume of Petrol or even the contamination percentage. Proceeding to run running a vehicle that is now starting to suffer the consequences of wrong fuel contamination will definitely cause even more damage affecting the fuel system components.
  3. Do you want assurance?
    In that case get it drained. No matter the contamination ratio, there is always some amount of risk linked with operating a Diesel engine on Diesel contaminated with the wrong fuel. Likely consequences of driving on the incorrect fuel normally include the engine refusing to start, running lumpy, loss in power, degradation of the high-pressure pump, worn or clogged injectors, and so forth. These are a few of the most typical Petrol in Diesel symptoms, and in the event that you observe any of them then stop and have it drained asap.

Petrol in Diesel Questions

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
