Jeep Fuel Drain


Putting Diesel in a Petrol Jeep is a common error. And what you have to do about it is based on various things. In case you want to know what you need to do about this then please read on.
Listed here the most crucial factors to be aware of whenever determining whether to get a fuel drain:

  1. How much Diesel did you put in to the Jeep, considering that the fuel tank capacity of your Jeep Cherokee is normally approximately 70 litres?
    1. A modest quantity of Diesel, as little as 3.5 litres of Diesel in a Petrol Cherokee will generally not really be a major problem. Experience has shown us that anything under 3.5 litres (almost 5% of the entire fuel tank) is often capable of being completely diluted by means of thoroughly filling up the remainder of the tank with the appropriate fuel.
      It is highly unusual to find a vehicle going through issues due to less than 5% wrong fuel contamination. Please remember it is very uncommon - definitely not impossible to find. You can get some cars that won't stand any level of fuel contamination at all.
    2. Somewhere between 3.5 and 7 litres of Diesel in the Jeep (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 those who break down. Whenever deciding on whether or not to chance it and just fill it up remember that it is just like betting it all on black - you have got a 50/50 possibility of it being ok.
    3. Anything over 7 litres of Diesel in your Petrol Cherokee must straightaway be drained seeing as your probability of driving with that amount of contamination is in all likelihood below one in fifty - seriously long odds.
  2. Put some Diesel in a Petrol Jeep and drove it: Have you detected any kind of performance problems since putting the wrong fuel in your Cherokee? If you have, have it emptied no matter the amount of Diesel or the contamination ratio. Continuing to drive running an automobile that is currently beginning to suffer the effects of fuel contamination will probably typically end up in progressively more harm affecting the fuel system components.
  3. Do you want security?
    Then simply just get it removed. Whatever the contamination ratio, there is invariably some extent of risk linked with driving a Petrol engine on fuel contaminated with the wrong fuel. Probable results of driving on the wrong fuel include things like the engine refusing to start, running lumpy, reduced power, degradation of the high-pressure pump, worn or bunged injectors, and so forth. These are several of the most typical Diesel in Petrol warning signs, and if you notice any of them then cease driving and get it removed as soon as possible.

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.
