Jeep Fuel Drain


Filling up with Diesel in a Petrol Jeep is a well-known mistake. And exactly what you want to do about it depends upon a number of factors. In case you want to find out what you ought to do to sort it out then please read on.
Right here are the main factors to think about when figuring out whether or not to have the car drained:

  1. What level of Diesel did you put in to the Jeep, keeping in mind that the fuel capacity of the Jeep Wrangler is usually about 72 litres?
    1. A tiny quantity of Diesel, something like 3.6 litres of Diesel in a Petrol Wrangler will usually not necessarily be a huge problem. Experience has demonstrated to us that anything under 3.6 litres (which is about 5% of the overall fuel tank volume) is often capable of being sufficiently diluted by means of entirely filling up the remainder of the tank with the right fuel.
      It is very rare to find a car or truck going through issues with less than 5% wrong fuel contamination. Keep in mind that it's infrequent - in no way impossible to find. There are actually a number of motor vehicles that will not stand any quantity of contamination at all.
    2. Between 3.6 and 7.2 litres of Diesel in the Jeep (5 to 10%) is really a 50/50 situation. Our working experience has proven that as many people get away with it as those who don't. Whenever you are trying to decide whether to chance it and simply top it up consider that it is the same as wagering it all on black - you've got a 50/50 chance of it working out.
    3. Anything in excess of 7.2 litres of Diesel in a Petrol Wrangler should really straightaway be drained out seeing that your likelihood of driving with that quantity of contamination is undoubtedly below one in 50 - truly big odds.
  2. Put some Diesel in a Petrol Jeep and drove it: Have you observed any kind of performance difficulties as a result of putting the wrong fuel in your Wrangler? If that's the case, get it drained irrespective of the volume of Diesel or the contamination ratio. Continuing to drive driving a car that is currently beginning to suffer the effects of wrong fuel contamination will probably just result in progressively more harm being done to the fuel system components.
  3. Do you want peace of mind?
    You should get it removed. Regardless of contamination percentage, there is always some extent of threat connected to running a Petrol vehicle on fuel contaminated with Diesel. Probable implications of driving on the incorrect fuel normally include the motor not starting, running unevenly, reduced power, wearing of the high-pressure pump, worn out or clogged injectors, and so forth. These are several of the most typical Diesel in Petrol symptoms, and in the event that you detect 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.
