Bentley Fuel Drain


Filling Diesel in a Petrol Bentley is a common mistake. And its remedy depends on a number of factors. If you want to find out what you have to do about this then please read on.
Listed below are the most crucial variables to take into account whenever figuring out whether to have a fuel drain:

  1. Exactly how much Diesel have you put in to the Bentley, considering that the fuel tank capacity of your Bentley Continental GT is usually about 90 litres?
    1. A modest amount of Diesel, as little as 4.5 litres of Diesel in a Petrol Continental GT will quite often not really be a major problem. Experience has proven to us that an amount less than 4.5 litres (which is approximately 5% of the total fuel tank volume) is generally capable of being adequately diluted by means of thoroughly filling up the rest of the tank with Petrol.
      It's rather rare to encounter a motor vehicle experiencing problems with under 5% wrong fuel contamination. Keep in mind it's rare - in no way impossible to find. There are actually a few automobiles that won't endure any level of contamination in the slightest.
    2. Somewhere between 4.5 and 9 litres of Diesel in the Bentley (5 to 10%) is really a 50/50 situation. Our expertise has revealed that as many motorists get away with it as those who don't. Whenever you are deciding whether or not to chance it and just fill it up recognise that it is just like gambling it all on black - you will have a 50/50 possibility of it being ok.
    3. Anything over 9 litres of Diesel in a Petrol Continental GT should really promptly be drained as your probability of driving with that amount of contamination is almost certainly lower than one in fifty - truly long odds.
  2. Put Diesel in a Petrol Bentley and drove it: Have you observed any performance issues ever since putting the incorrect fuel in the Continental GT? If that's the case, have it emptied irrespective of the amount of Diesel or even the contamination percentage. Continuing to run driving a motor vehicle that is beginning to suffer the consequences of fuel contamination can typically be responsible for increasing amounts of damage affecting your fuel system components.
  3. Would you like assurance?
    Simply get it removed. Regardless of contamination ratio, there is invariably some amount of risk caused by operating a Petrol motor on Petrol contaminated with Diesel. Possible outcomes of driving a car on the wrong fuel can include the engine not starting, running lumpy, loss of power, degradation of the high-pressure pump, worn or blocked injectors, and the like. These are a few of the most frequently seen Diesel in Petrol signs and symptoms, and in the event that you observe any of them then stop and have it drained asap.

Diesel in Petrol FAQs

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.
