Subaru Fuel Drain


Filling Petrol in a Diesel Subaru is a regular mistake to make. And its remedy will depend on an assortment of things. Assuming you want to find out what you ought to do to sort it out then continue reading.
Listed below are the main factors to take into consideration whenever determining whether or not to get your car drained:

  1. How much Petrol did you put in to the Subaru, taking into consideration that the fuel capacity of your Subaru Legacy 2.0D is normally about 64 litres?
    1. A modest quantity of Petrol, less than 3.2 litres of Petrol in a Diesel Legacy 2.0D will in most cases not be a significant problem. Experience has proven to us that quantities under 3.2 litres (roughly 5% of the whole fuel tank) is in many instances capable of being completely diluted simply by wholly filling up the remainder of the tank with the correct fuel.
      It is pretty rare to encounter a car going through issues due to lower than 5% incorrect fuel contamination. Keep in mind it's uncommon - not impossible to find. You can get a few motor vehicles that don't endure any level of contamination whatsoever.
    2. In between 3.2 and 6.4 litres of Petrol in the Subaru (5 to 10%) is really a 50/50 situation. Our experience has shown that as many people get away with this as those people who don't. Whenever deciding whether or not to chance it and just simply fill it up bear in mind that it is exactly like gambling everything on black - you have a 50/50 chance of it working out.
    3. Anything over 6.4 litres of Petrol in your Diesel Legacy 2.0D must right away be drained since your likelihood of succeeding with that quantity of contamination is almost certainly lower than one in 50 - truly huge odds.
  2. Put Petrol in a Diesel Subaru and drove it: Have you spotted any kind of performance problems ever since putting the incorrect fuel in the Legacy 2.0D? In that case, get it drained irrespective of the amount of Petrol or the contamination percentage. Still driving a car that is already beginning to suffer the consequences of wrong fuel contamination can likely be responsible for even more damage being done to your fuel system parts.
  3. Do you want assurance?
    Then get it drained. Regardless of contamination ratio, there is always a certain level of danger associated with running a Diesel engine on Diesel contaminated with the incorrect fuel. Likely results of driving on the incorrect fuel normally include the engine refusing to start, running lumpy, reduced power, wearing of the high-pressure pump, worn out or blocked injectors, and so on. These are a few of the most common Petrol in Diesel signs and symptoms, and if you observe any of them then stop driving and have it drained right now.

Petrol in Diesel Questions

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.
