Jaguar Fuel Drain


Filling Diesel in a Petrol Jaguar is a fairly typical error. And its remedy hinges on an assortment of factors. If you want to find out what you should do to fix it then keep on reading.
Listed here are the most important factors to take into consideration when figuring out whether to get your car drained:

  1. Exactly how much Diesel have you put in to the Jaguar, considering that the fuel capacity of your Jaguar xK is in most cases approximately 71 litres?
    1. Hardly any Diesel, less than 3.55 litres of Diesel in a Petrol xK will usually not necessarily be a major problem. Experience has proven to us that anything less than 3.55 litres (approximately 5% of the whole fuel tank capacity) is oftentimes able to be sufficiently diluted through completely filling the rest of the tank with the right fuel.
      It is extremely rare to come across an automobile going through issues due to less than 5% wrong fuel contamination. Do not forget that it is very infrequent - certainly not impossible to encounter. There are certain cars that don't endure any degree of contamination at all.
    2. Anywhere between 3.55 and 7.1 litres of Diesel in the Jaguar (from 5 to 10%) is a 50/50 condition. Our working experience has proven that as many motorists get away with this as those people who don't. Any time you're figuring out whether or not to risk it and just simply top it up bear in mind that it is exactly like betting it all on black - you have got a 50/50 possibility of it working.
    3. Anything in excess of 7.1 litres of Diesel in a Petrol xK should really as soon as possible be drained seeing as your likelihood of driving with that amount of contamination is almost certainly less than one in fifty - definitely huge odds.
  2. Put Diesel in a Petrol Jaguar and drove it: Have you seen any performance difficulties since putting the bad fuel in your xK? If so, get it emptied regardless of the amount of Diesel or even the contamination ratio. Continually driving a vehicle that is now starting to suffer from the consequences of fuel contamination will likely be responsible for more and more damage being done to the fuel system.
  3. Are you interested in peace of mind?
    In that case get it removed. Whatever the contamination percentage, there is always some degree of danger affiliated with running a Petrol motor on Petrol contaminated with Diesel. Probable outcomes of driving a car on the incorrect fuel normally include the engine not starting, running unevenly, loss of power, degradation of the high-pressure pump, worn out or blocked injectors, etc. These are several of the commonest Diesel in Petrol signs or symptoms, and if you recognise any of them cease driving and have it drained immediately.

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.
