Rolls-Royce Fuel Drain


Putting Diesel in a Petrol Rolls-Royce is a regularly occurring problem. And what you have to do about it depends upon various factors. If you would like to find out what it is advisable to do about this then stay with me.
Right here are the key factors to take into account when deciding on whether to get a fuel drain:

  1. Exactly how much Diesel did you put in to the Rolls-Royce, keeping in mind that the fuel tank capacity of your Rolls-Royce Phantom is in most cases roughly 100 litres?
    1. A tiny amount of Diesel, as little as 5 litres of Diesel in a Petrol Phantom will usually not be a huge problem. Experience has demonstrated to us that an amount under 5 litres (close to 5% of the entire fuel tank capacity) is frequently able to be completely diluted by means of entirely filling the rest of the tank with the right fuel.
      It is extremely unusual to encounter a vehicle having difficulties with less than 5% wrong fuel contamination. Please remember it's uncommon - definitely not impossible to find. There are a few cars that won't endure any amount of fuel contamination at all.
    2. Anywhere between 5 and 10 litres of Diesel in the Rolls-Royce (from 5 to 10%) is more of a 50/50 situation. Our experience has confirmed that as many drivers get away with it as those who break down. When you are deciding whether or not to chance it and simply fill it up consider that it is just like gambling everything on black - you have got a 50/50 chance of it being ok.
    3. Anything over 10 litres of Diesel in a Petrol Phantom should really as soon as possible be drained because your probability of driving with this quantity of contamination is very likely below one in 50 - truly long odds.
  2. Put Diesel in a Petrol Rolls-Royce and drove it: Have you noticed any performance troubles since putting the bad fuel in your Phantom? If you have, have it drained no matter the volume of Diesel or even the contamination percentage. Still running an automobile that is currently beginning to suffer the consequences of wrong fuel contamination will likely cause more and more damage affecting the fuel system components.
  3. Do you want assurance?
    Simply get it emptied. Whatever the contamination percentage, there is inevitably some degree of risk in connection with running a Petrol motor on fuel contaminated with Diesel. Possible outcomes of driving a car on the incorrect fuel include things like the motor not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn or bunged injectors, and so forth. These are a few of the most frequently seen Diesel in Petrol signs or symptoms, and in the event that you recognise any of them then stop and get it removed as soon as possible.

Diesel in Petrol Questions

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.
