Jaguar Fuel Drain


Putting Petrol in a Diesel Jaguar is a usual error. And its solution depends on a number of things. In the event that you would like to know what you must do about this then please read on.
Listed here the main factors to consider when deciding whether or not to have your car drained:

  1. What level of Petrol did you put in to the Jaguar, taking into consideration that the fuel tank capacity of your Jaguar S-Type Diesel is normally around 70 litres?
    1. A tiny quantity of Petrol, as little as 3.5 litres of Petrol in a Diesel S-Type Diesel will in most situations not be a significant problem. Experience has proven to us that an amount under 3.5 litres (which is roughly 5% of the whole fuel tank volume) is frequently capable of being sufficiently diluted by means of wholly filling the tank with the appropriate fuel.
      It's highly unusual to find a motor vehicle suffering from problems due to lower than 5% wrong fuel contamination. Remember that it is infrequently found - certainly not impossible to encounter. There are actually a few vehicles that don't stand any amount of contamination in the slightest.
    2. In between 3.5 and 7 litres of Petrol in the Jaguar (from 5 to 10%) is more of a 50/50 situation. Our practical experience has shown that as many drivers get away with it as all those who break down. When trying to decide whether or not to chance it and just simply fill it up consider that it is exactly like betting it all on black - you will have a 50/50 chance of it working.
    3. Anything in excess of 7 litres of Petrol in your Diesel S-Type Diesel really should straight away be removed seeing that your likelihood of getting away with this quantity of contamination is undoubtedly below one in fifty - genuinely long odds.
  2. Put Petrol in a Diesel Jaguar and drove it: Have you noticed any kind of performance concerns as a result of putting the wrong fuel in the S-Type Diesel? In that case, get it drained no matter the quantity of Petrol or even the contamination percentage. Continuing to drive running a vehicle that is currently starting to suffer the effect of wrong fuel contamination will typically bring about increasing amounts of harm affecting the fuel system.
  3. Are you looking for security?
    Simply get it drained. No matter the contamination ratio, there is invariably some extent of risk connected to running a Diesel motor on Diesel contaminated with the incorrect fuel. Possible consequences of driving on the incorrect fuel normally include the engine refusing to start, running unevenly, reduced power, degradation of the high-pressure pump, damaged or clogged injectors, and the like. These are some of the most typical Petrol in Diesel warning signs, and in the event that you observe any of them cease driving and have 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.
