Jaguar Fuel Drain


Filling up with Petrol in a Diesel Jaguar is a very common error. And its remedy varies according to a variety of things. Assuming you want to know what it is best to do to fix it then keep reading.
These are the key factors to to consider when determining whether to have the car drained:

  1. How much Petrol did you put in the Jaguar, taking into consideration that the fuel capacity of the Jaguar xF Diesel is most likely approximately 69 litres?
    1. Hardly any Petrol, something like 3.45 litres of Petrol in a Diesel xF Diesel will in most cases not really be a major problem. Experience has proven to us that an amount less than 3.45 litres (which is approximately 5% of the overall fuel tank volume) is very often capable of being adequately diluted by completely topping the remainder of the tank with the right fuel.
      It's extremely unusual to find an automobile going through problems due to less than 5% wrong fuel contamination. Please remember it is very rare - definitely not impossible to find. There are a number of vehicles that won't stand any level of fuel contamination whatsoever.
    2. In between 3.45 and 6.9 litres of Petrol in the Jaguar (from 5 to 10%) is more of a 50/50 situation. Our experience has shown us that as many drivers get away with it as those who break down. Any time you are deciding upon whether or not to chance it and basically fill it up remember that it is very much like betting it all on black - you will have a 50/50 possibility of it being ok.
    3. Anything in excess of 6.9 litres of Petrol in a Diesel xF Diesel should really as soon as possible be drained out since your probability of driving with this quantity of contamination is more than likely lower than one in 50 - genuinely big odds.
  2. Put some Petrol in a Diesel Jaguar and drove it: Have you noticed any kind of performance problems after putting the wrong fuel in the xF Diesel? In that case, get it removed irrespective of the amount of Petrol or even the contamination percentage. Continually running an automobile that is starting to suffer from the effect of fuel contamination will probably just cause more damage affecting the fuel system parts.
  3. Are you looking for reassurance?
    In that case get it removed. Regardless of contamination percentage, there is always a certain level of danger connected with operating a Diesel vehicle on fuel contaminated with the wrong fuel. Likely results of driving a car on the incorrect fuel can include the engine not starting, running unevenly, loss in power, degradation of the high-pressure pump, worn or clogged injectors, and the like. These are some of the commonest Petrol in Diesel warning signs, and if you recognise any of them then stop and get it removed immediately.

Petrol in Diesel FAQs

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
