Jeep Fuel Drain


Filling Diesel in a Petrol Jeep is a usual problem. And what you should do about it hinges on several things. In the event that you want to know what you need to do to sort it out then please read on.
Right here are the most important variables to to consider when determining whether to get your car drained:

  1. Exactly how much Diesel have you put in to the Jeep, bearing in mind that the fuel tank capacity of the Jeep Grand Cherokee is usually approximately 87 litres?
    1. A modest quantity of Diesel, something like 4.35 litres of Diesel in a Petrol Grand Cherokee will in most situations not necessarily be a big problem. Experience has demonstrated to us that quantities under 4.35 litres (which is close to 5% of the entire fuel tank capacity) is very often capable of being completely diluted through completely topping up the tank with the appropriate fuel.
      It's pretty unusual to encounter a vehicle having issues with lower than 5% wrong fuel contamination. Bear in mind that it's infrequently found - definitely not impossible to find. There are actually a few automobiles that won't endure any degree of contamination in the slightest.
    2. Between 4.35 and 8.7 litres of Diesel in the Jeep (from 5 to 10%) is really a 50/50 situation. Our working experience has confirmed that as many drivers get away with it as all those who don't. When trying to decide whether to chance it and simply top it up recognise that it is exactly like gambling it all on black - you have a 50/50 chance of it working out.
    3. Anything above 8.7 litres of Diesel in your Petrol Grand Cherokee must straight away be removed seeing as your probability of succeeding with that level of contamination is more than likely below one in fifty - definitely long odds.
  2. Put Diesel in a Petrol Jeep and drove it: Have you observed any kind of performance concerns ever since putting the wrong fuel in your Grand Cherokee? If so, get it emptied irrespective of the quantity of Diesel or even the contamination ratio. Continually driving a motor vehicle that is currently starting to suffer the effects of fuel contamination will definitely cause even more harm being caused to the fuel system parts.
  3. Are you looking for reassurance?
    Then get it removed. No matter the contamination ratio, there is invariably a certain level of risk affiliated with running a Petrol vehicle on fuel contaminated with the wrong fuel. Probable implications of driving a car on the incorrect fuel normally include the motor not starting, running unevenly, loss of power, degradation of the high-pressure pump, damaged or clogged injectors, and so forth. These are some of the most frequently seen Diesel in Petrol signs and symptoms, and should you detect any of them stop driving and have it removed as soon as possible.

Diesel in Petrol FAQs

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.
