Jaguar Fuel Drain


Putting Diesel in a Petrol Jaguar is a very common problem. And what you want to do about it depends on a few things. Assuming you would like to know what it is best to do to sort it out then please read on.
Listed below are the main variables to be aware of when determining whether to have a fuel drain:

  1. What amount of Diesel have you put in the Jaguar, considering that the fuel tank capacity of the Jaguar xF is in most cases approximately 69 litres?
    1. Hardly any Diesel, something like 3.45 litres of Diesel in a Petrol xF will generally not necessarily be a major problem. Experience has taught us that an amount less than 3.45 litres (which is close to 5% of the entire fuel tank volume) is quite often able to be sufficiently diluted by completely topping the tank with the right fuel.
      It's quite uncommon to encounter a car experiencing problems due to less than 5% wrong fuel contamination. Be aware that it is very rare - certainly not impossible to encounter. There are some vehicles that won't endure any level of contamination whatsoever.
    2. Between 3.45 and 6.9 litres of Diesel in the Jaguar (from 5 to 10%) is more of a 50/50 condition. Our practical experience has confirmed that as many motorists get away with it as those people who break down. Whenever you are figuring out whether or not to risk it and simply top it up remember that it is the same as gambling it all on black - you have got a 50/50 possibility of it working.
    3. Anything in excess of 6.9 litres of Diesel in your Petrol xF should right away be removed because your likelihood of driving with that amount of contamination is probably below one in 50 - extremely big odds.
  2. Put Diesel in a Petrol Jaguar and drove it: Have you noticed any kind of performance troubles since putting the wrong fuel in the xF? If you have, get it removed no matter the volume of Diesel or the contamination ratio. Still running an automobile that is already beginning to suffer the consequences of fuel contamination will probably just result in increasing amounts of harm being done to your fuel system components.
  3. Are you interested in peace of mind?
    Simply get it emptied. Whatever the contamination ratio, there is always some degree of danger associated with driving a Petrol engine on Petrol contaminated with the incorrect fuel. Probable final outcomes of driving on the incorrect fuel include the motor refusing to start, running unevenly, reduced power, degradation of the high-pressure pump, worn or blocked injectors, and so forth. These are some of the commonest Diesel in Petrol symptoms, and in the event that you detect any of them then stop and get it removed right away.

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.
