Jeep Fuel Drain


Filling Petrol in a Diesel Jeep is a very common problem. And exactly what you have to do about it is dependent upon a number of things. If perhaps you would like to know what you must do to fix it then keep on reading.
Listed here the most crucial variables to take into consideration when determining whether or not to have the car drained:

  1. Exactly how much Petrol have you put in the Jeep, bearing in mind that the fuel tank capacity of the Jeep Wrangler CRD is usually around 66 litres?
    1. A tiny amount of Petrol, something like 3.3 litres of Petrol in a Diesel Wrangler CRD will normally not necessarily be a big problem. Experience has taught us that an amount under 3.3 litres (which is close to 5% of the entire fuel tank capacity) is sometimes capable of being sufficiently diluted by totally topping up the tank with Diesel.
      It is very rare to find a motor vehicle experiencing problems with below 5% wrong fuel contamination. Keep in mind that it is very infrequent - definitely not impossible to encounter. There are actually a number of vehicles that don't endure any amount of fuel contamination in the slightest.
    2. Between 3.3 and 6.6 litres of Petrol in the Jeep (5 to 10%) is more of a 50/50 situation. Our expertise has shown that as many people get away with this as all those who don't. Whenever you are deciding whether or not to risk it and simply fill it up remember that it is the same as betting everything on black - you will have a 50/50 chance of it being ok.
    3. Anything above 6.6 litres of Petrol in your Diesel Wrangler CRD should right away be drained out as your probability of getting away with that quantity of contamination is more than likely below one in 50 - truly long odds.
  2. Put some Petrol in a Diesel Jeep and drove it: Have you observed any kind of performance difficulties as a result of putting the wrong fuel in your Wrangler CRD? If you have, have it removed regardless of the quantity of Petrol or the contamination ratio. Still driving a car that is currently beginning to suffer from the effect of wrong fuel contamination can just end up in more harm being done to the fuel system parts.
  3. Would you like reassurance?
    Then get it emptied. Regardless of contamination ratio, there is invariably some degree of danger connected with running a Diesel engine on Diesel contaminated with Petrol. Probable implications of driving on the wrong fuel include things like the motor not starting, running lumpy, loss of power, degradation of the high-pressure pump, worn or blocked injectors, and the like. These are some of the most frequently seen Petrol in Diesel signs or symptoms, and should you observe any of them stop and get it drained 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.
