Wrong Fuel Bentley

If you have put diesel in a petrol Bentley then you will want to know what to do about it, how to get it out, if it’s safe to drive, and probably a host of other questions.

We are here to answer those questions and get you back on the road again.

Is having the wrong fuel in a Bentley a problem?

In most cases, yes. Petrol in a diesel fuel system can cause issues with a loss of lubrication resulting in damaged fuel pumps and injectors. It can also lead to the deterioration of fuel lines, seals and filters.

Running a diesel vehicle on petrol can also cause a number of problems – including burnt out spark-plugs, thinned out oil (leading to a lack of engine lubrication), and even complete engine failure.

How to drain a misfuelled Bentley?

The easiest way to get the wrong fuel out of you Bentley is to call us. We offer a specialist Bentley misfuel service where we come out to attend the vehicle wherever it is. We will drain the fuel tank (or tanks if there are more than one), flush out the fuel lines, filters and pumps, re-prime the system with clean fuel, and get the engine running again.

Can you drive a misfuelled Bentley?

The safe answer is always no. Putting any amount of the wrong fuel in a car can cause damage to the fuel system.

You will often find that after filling up with the wrong fuel the driver is unaware of the fact and attempts to drive off down the road. In most cases the car will get a couple of miles before it starts to exhibit the tell-tale signs of misfuelling (loss of power, excess smoke, cutting out, or failing to restart after being turned off). These few miles will be because the engine is running on the remaining clean fuel left in the fuel lines and filter. Once the contaminated fuel reaches the engine it’s a completely different story altogether.

How quickly it starts to misbehave depends on the fuel system, the amount of correct fuel in the vehicle, and the volume of incorrect fuel pumped into the tank.

These last two factors will determine the contamination ratio in the fuel tank. We generally say that if you have more than 5% contamination in your fuel tank you should get it drained out as soon as possible*.

If you want to know your contamination ratio we have provided a list at the bottom of the page of the most common Bentley models and variants. This list gives their estimated fuel tank capacity and an indicator of how many litres of fuel equates to five percent.

If you have put more than this amount into the tank then give us a call right away to get it drained and cleaned out.

* NOTE: This 5% contamination ratio advice is based on our customer feedback and years of experience in dealing with misfuelled Bentleys. Bear in mind that any amount of contaminated fuel can damage the engine. To avoid any uncertainty please consult Bentley’s guidelines on what level of contamination is acceptable.

Wrong Fuel Bentley Questions

When someone has put diesel in a petrol Bentley 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 Bentley 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 misfuelled Bentley 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 wrong fuel can I get away with in a Bentley?

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 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.
