Subaru Fuel Drain


Filling Diesel in a Petrol Subaru is a common problem. And its remedy varies according to several different things. In the event that you would like to know what you have to do about it then please read on.
Listed here are the most important variables to take into consideration when making a decision whether or not to get your car drained:

  1. What amount of Diesel have you put into the Subaru, considering that the fuel tank capacity of the Subaru Forester is in most cases roughly 60 litres?
    1. A modest quantity of Diesel, less than 3 litres of Diesel in a Petrol Forester will most of the time not really be a big problem. Experience has taught us that anything less than 3 litres (which is almost 5% of the total fuel tank volume) is in many instances able to be adequately diluted by entirely filling the rest of the tank with the appropriate fuel.
      It is very unusual to come across a car going through issues because of less than 5% incorrect fuel contamination. Be aware that it is very infrequently found - definitely not impossible to encounter. There are a few cars that will not endure any quantity of fuel contamination whatsoever.
    2. In between 3 and 6 litres of Diesel in the Subaru (5 to 10%) is really a 50/50 condition. Our working experience demonstrates that as many motorists get away with this as those who don't. Any time you are figuring out whether or not to risk it and basically fill it up remember that it is just like wagering everything on black - you will have a 50/50 chance of it working out.
    3. Anything in excess of 6 litres of Diesel in your Petrol Forester should really straightaway be drained seeing as your likelihood of driving with that amount of contamination is probably less than one in fifty - truly big odds.
  2. Put some Diesel in a Petrol Subaru and drove it: Have you detected any kind of performance problems since putting the bad fuel in your Forester? If that's the case, have it drained irrespective of the amount of Diesel or even the contamination percentage. Proceeding to drive driving a vehicle that is now starting to suffer the consequences of wrong fuel contamination will probably just cause more damage affecting your fuel system components.
  3. Do you want assurance?
    You should get it removed. Regardless of contamination ratio, there is invariably a certain level of danger linked with running a Petrol vehicle on Petrol contaminated with the incorrect fuel. Possible outcomes of driving on the wrong fuel include things like the engine not starting, running unevenly, losing power, wearing of the high-pressure pump, worn out or clogged injectors, and the like. These are a few of the most common Diesel in Petrol symptoms, and in the event that you recognise any of them then cease driving and get it drained right away.

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.
