Jeep Fuel Drain


Putting Petrol in a Diesel Jeep is a regular mistake to make. And its remedy varies according to a number of factors. If perhaps you would like to know what you need to do about this then keep reading.
These are the most crucial factors to to consider whenever determining whether or not to get the car drained:

  1. Exactly how much Petrol did you put in to the Jeep, keeping in mind that the fuel capacity of the Jeep Grand Cherokee CRD is probably around 78 litres?
    1. A modest amount of Petrol, less than 3.9 litres of Petrol in a Diesel Grand Cherokee CRD will in most situations not necessarily be a huge problem. Experience has taught us that quantities less than 3.9 litres (which is 5% of the overall fuel tank) is usually capable of being sufficiently diluted simply by completely filling up the tank with the right fuel.
      It's rather uncommon to come across a car suffering from issues with under 5% wrong fuel contamination. Remember that it is very unusual - not impossible to encounter. You can get a number of motor vehicles that won't endure any level of contamination in the slightest.
    2. In between 3.9 and 7.8 litres of Petrol in the Jeep (5 to 10%) is more of a 50/50 situation. Our practical experience has demonstrated that as many drivers get away with it as all those who break down. Whenever figuring out whether or not to risk it and just simply fill it up remember that it is very much like betting your car on black - you have got a 50/50 possibility of it working out.
    3. Anything in excess of 7.8 litres of Petrol in a Diesel Grand Cherokee CRD ought to straightaway be drained out since your probability of driving with this quantity of contamination is almost certainly below one in 50 - extremely huge odds.
  2. Put some Petrol in a Diesel Jeep and drove it: Have you observed any performance troubles since putting the wrong fuel in the Grand Cherokee CRD? If you have, have it drained irrespective of the amount of Petrol or even the contamination percentage. Continually running a vehicle that is now beginning to suffer from the effects of wrong fuel contamination will likely end up in more damage affecting your fuel system components.
  3. Are you interested in reassurance?
    In that case get it removed. No matter the contamination percentage, there is invariably some extent of threat in connection with running a Diesel motor on fuel contaminated with the incorrect fuel. Probable implications of driving a vehicle on the wrong fuel include the motor refusing to start, running unevenly, losing power, wearing of the high-pressure pump, worn out or clogged injectors, and so on. These are several of the commonest Petrol in Diesel signs or symptoms, and should you recognise any of them then stop and have it removed right away.

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.
