Subaru Fuel Drain


Putting Petrol in a Diesel Subaru is a well-known mistake. And its remedy depends on various factors. If you would like to find out what you ought to do to fix it then keep reading.
Listed here are the main factors to be aware of whenever determining whether or not to have the car drained:

  1. Exactly how much Petrol have you put in the Subaru, bearing in mind that the fuel tank capacity of your Subaru Outback 2.0D is probably about 64 litres?
    1. A modest quantity of Petrol, as little as 3.2 litres of Petrol in a Diesel Outback 2.0D will quite often not really be a huge problem. Experience has proven to us that an amount less than 3.2 litres (which is roughly 5% of the entire fuel tank volume) is sometimes capable of being adequately diluted by means of wholly topping up the tank with Diesel.
      It is extremely uncommon to come across a motor vehicle suffering from difficulties due to lower than 5% wrong fuel contamination. Be aware that it is infrequent - not impossible to find. There are actually a number of automobiles that don't stand any degree of contamination whatsoever.
    2. In between 3.2 and 6.4 litres of Petrol in the Subaru (5 to 10%) is a 50/50 situation. Our practical experience has shown that as many drivers get away with this as those who don't. Any time you are trying to decide whether to chance it and just top it up remember that it is much like betting it all on black - you have got a 50/50 chance of it working out.
    3. Anything in excess of 6.4 litres of Petrol in your Diesel Outback 2.0D must straight away be drained seeing that your probability of driving with that amount of contamination is almost certainly less than one in 50 - seriously big odds.
  2. Put some Petrol in a Diesel Subaru and drove it: Have you spotted any performance troubles ever since putting the bad fuel in your Outback 2.0D? In that case, have it emptied irrespective of the quantity of Petrol or even the contamination ratio. Proceeding to drive driving a vehicle that is beginning to suffer the effect of fuel contamination will likely result in more and more damage affecting your fuel system parts.
  3. Are you interested in reassurance?
    In that case get it removed. No matter the contamination percentage, there is inevitably some extent of risk associated with operating a Diesel vehicle on Diesel contaminated with Petrol. Likely implications of driving a car on the incorrect fuel can include the motor refusing to start, running lumpy, lack of power, degradation of the high-pressure pump, worn out or clogged injectors, etc. These are a few of the most typical Petrol in Diesel symptoms, and if you recognise any of them cease driving and have it drained asap.

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.
