Jeep Fuel Drain


Filling Diesel in a Petrol Jeep is a well-known problem. And its remedy will depend on an assortment of things. If you want to find out what you must do about this then continue reading.
Here are the key variables to think about whenever figuring out whether to have a fuel drain:

  1. How much Diesel have you put into the Jeep, keeping in mind that the fuel tank capacity of your Jeep Commander is normally approximately 78 litres?
    1. A tiny amount of Diesel, less than 3.9 litres of Diesel in a Petrol Commander will in most cases not really be a significant problem. Experience has demonstrated to us that anything under 3.9 litres (which is roughly 5% of the whole fuel tank capacity) is in many instances able to be completely diluted by means of completely topping the rest of the tank with Petrol.
      It's extremely uncommon to find a car having difficulties because of less than 5% incorrect fuel contamination. Be aware that it's infrequently found - not impossible to find. There are actually certain vehicles that will not stand any degree of contamination at all.
    2. Somewhere between 3.9 and 7.8 litres of Diesel in the Jeep (5 to 10%) is more of a 50/50 scenario. Our experience has demonstrated that as many people get away with it as those who don't. Any time you're trying to decide whether or not to risk it and simply fill it up recognise that it is the same thing as gambling everything on black - you have got a 50/50 chance of it working.
    3. Anything over 7.8 litres of Diesel in a Petrol Commander really should straightaway be drained out because your probability of getting away with that amount of contamination is more than likely below one in 50 - genuinely huge odds.
  2. Put Diesel in a Petrol Jeep and drove it: Have you observed any kind of performance concerns as a result of putting the wrong fuel in the Commander? If you have, get it drained no matter the quantity of Diesel or the contamination ratio. Still driving a motor vehicle that is starting to suffer the effect of fuel contamination will likely cause more harm being caused to the fuel system components.
  3. Are you looking for peace of mind?
    Simply get it drained. Regardless of contamination percentage, there is always a certain level of threat associated with operating a Petrol motor on fuel contaminated with Diesel. Likely implications of driving a vehicle on the wrong fuel can include the motor refusing to start, running unevenly, decrease in power, wearing of the high-pressure pump, worn out or bunged injectors, and so on. These are a few of the most typical Diesel in Petrol signs and symptoms, and in the event that you observe any of them then stop and get it drained immediately.

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.
