Bentley Fuel Drain


Filling Diesel in a Petrol Bentley is a well-known mistake to make. And its solution varies according to a number of factors. If you want to know what it is best to do about this then stay with me.
Right here are the main variables to take into account whenever figuring out whether or not to get the car drained:

  1. What amount of Diesel have you put into the Bentley, keeping in mind that the fuel capacity of your Bentley Azure is probably approximately 96 litres?
    1. Hardly any Diesel, as little as 4.8 litres of Diesel in a Petrol Azure will normally not be a major problem. Experience has taught us that anything less than 4.8 litres (roughly 5% of the whole fuel tank volume) is in many instances able to be adequately diluted by entirely filling up the remainder of the tank with Petrol.
      It is pretty unusual to encounter a motor vehicle going through problems due to lower than 5% wrong fuel contamination. Keep in mind it is unusual - certainly not impossible to find. There are actually a few cars that will not endure any degree of fuel contamination at all.
    2. In between 4.8 and 9.6 litres of Diesel in the Bentley (from 5 to 10%) is a 50/50 scenario. Our experience has confirmed that as many people get away with this as those who break down. Whenever deciding on whether or not to risk it and just simply fill it up bear in mind that it is very much like wagering everything on black - you've got a 50/50 chance of it working out.
    3. Anything more than 9.6 litres of Diesel in a Petrol Azure should really right away be drained because your likelihood of getting away with that quantity of contamination is undoubtedly less than one in 50 - definitely big odds.
  2. Put some Diesel in a Petrol Bentley and drove it: Have you noted any kind of performance difficulties since putting the wrong fuel in the Azure? If you have, get it emptied irrespective of the amount of Diesel or the contamination percentage. Continuing to run running a motor vehicle that is currently starting to suffer from the effect of wrong fuel contamination will likely bring about progressively more damage being caused to your fuel system.
  3. Are you looking for peace of mind?
    You should get it removed. Regardless of the contamination ratio, there is always some amount of threat associated with operating a Petrol engine on Petrol contaminated with the incorrect fuel. Likely final outcomes of driving on the wrong fuel can include the engine refusing to start, running unevenly, losing power, degradation of the high-pressure pump, worn out or clogged injectors, and so forth. These are several of the most common Diesel in Petrol signs and symptoms, and in the event that you notice any of them stop driving and have it removed immediately.

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.
