Jaguar Fuel Drain


Putting Petrol in a Diesel Jaguar is a very common mistake. And what you have to do about it depends upon an assortment of things. In case you would like to find out what you have to do to sort it out then continue reading.
Right here are the most important factors to consider when figuring out whether or not to have the car drained:

  1. What level of Petrol have you put in to the Jaguar, bearing in mind that the fuel tank capacity of your Jaguar xJ Diesel is most likely approximately 82 litres?
    1. A small amount of Petrol, as little as 4.1 litres of Petrol in a Diesel xJ Diesel will in most situations not really be a major problem. Experience has taught us that anything under 4.1 litres (approximately 5% of the fuel tank) is quite often capable of being adequately diluted by means of totally topping the remainder of the tank with Diesel.
      It is very rare to find a motor vehicle going through problems because of below 5% wrong fuel contamination. Bear in mind that it is uncommon - certainly not impossible to find. There are actually certain vehicles that will not stand any amount of contamination at all.
    2. Anywhere between 4.1 and 8.2 litres of Petrol in the Jaguar (5 to 10%) is a 50/50 condition. Our experience has shown us that as many people get away with it as all those who break down. When you are figuring out whether or not to chance it and just top it up consider that it is just like gambling your car on black - you have a 50/50 possibility of it working out.
    3. Anything above 8.2 litres of Petrol in your Diesel xJ Diesel really should straight away be removed as your likelihood of succeeding with this quantity of contamination is more than likely less than one in 50 - definitely big odds.
  2. Put some Petrol in a Diesel Jaguar and drove it: Have you seen any performance concerns since putting the wrong fuel in your xJ Diesel? If that's the case, get it removed irrespective of the volume of Petrol or even the contamination ratio. Still driving a car that is currently starting to suffer the consequences of wrong fuel contamination will probably typically be responsible for progressively more damage being done to the fuel system.
  3. Do you need reassurance?
    Simply get it removed. Regardless of contamination ratio, there is inevitably some amount of danger in connection with driving a Diesel motor on Diesel contaminated with the incorrect fuel. Likely results of driving on the wrong fuel include things like the engine not starting, running unevenly, lack of power, wearing of the high-pressure pump, worn out or bunged injectors, and so on. These are some of the most common Petrol in Diesel symptoms, and should you detect 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.
