Bentley Fuel Drain


Filling up with Diesel in a Petrol Bentley is a very common error. And exactly what you should do about it is based on various things. If perhaps you would like to know what you must do to sort it out then keep reading.
Listed here the main factors to keep in mind whenever choosing whether to have a fuel drain:

  1. How much Diesel have you put in to the Bentley, keeping in mind that the fuel capacity of the Bentley Arnage is in most cases roughly 94 litres?
    1. A tiny amount of Diesel, something like 4.7 litres of Diesel in a Petrol Arnage will normally not be a major problem. Experience has proven to us that an amount under 4.7 litres (which is about 5% of the entire fuel tank capacity) is in many instances able to be sufficiently diluted by wholly topping the rest of the tank with Petrol.
      It's pretty uncommon to encounter an automobile suffering from difficulties due to lower than 5% incorrect fuel contamination. Do not forget that it's uncommon - definitely not impossible to encounter. You will discover some motor vehicles that will not stand any degree of contamination at all.
    2. Anywhere between 4.7 and 9.4 litres of Diesel in the Bentley (from 5 to 10%) is more of a 50/50 condition. Our experience has demonstrated that as many motorists get away with it as all those who break down. Whenever deciding on whether or not to chance it and just simply top it up remember that it is much like wagering all of it on black - you will have a 50/50 chance of it working out.
    3. Anything more than 9.4 litres of Diesel in a Petrol Arnage really should right away be removed as your probability of succeeding with that amount of contamination is more than likely below one in fifty - definitely big odds.
  2. Put Diesel in a Petrol Bentley and drove it: Have you noted any kind of performance issues after putting the bad fuel in the Arnage? If you have, get it drained irrespective of the quantity of Diesel or even the contamination percentage. Continually driving a motor vehicle that is currently starting to suffer the effect of wrong fuel contamination can likely bring about more and more harm being done to the fuel system components.
  3. Do you need assurance?
    Then simply just get it emptied. No matter the contamination ratio, there is invariably some extent of danger caused by driving a Petrol motor on Petrol contaminated with the wrong fuel. Likely results of driving a vehicle on the incorrect fuel include things like the motor not starting, running unevenly, decrease in power, wearing of the high-pressure pump, damaged or bunged injectors, and so on. These are a few of the most frequently seen Diesel in Petrol warning signs, and if you observe any of them then cease driving and have it removed 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.
