Subaru Fuel Drain


Filling Diesel in a Petrol Subaru is a fairly typical mistake. And exactly what you should do about it varies according to several different things. If you want to find out what it is advisable to do to sort it out then please read on.
These are the main variables to to consider when deciding whether to get a fuel drain:

  1. Exactly how much Diesel have you put in the Subaru, taking into consideration that the fuel capacity of the Subaru SVx is in most cases around 70 litres?
    1. A small quantity of Diesel, as little as 3.5 litres of Diesel in a Petrol SVx will generally not really be a massive problem. Experience has taught us that anything under 3.5 litres (which is close to 5% of the overall fuel tank) is often able to be sufficiently diluted through thoroughly topping the remainder of the tank with the right fuel.
      It is relatively rare to encounter an automobile going through issues with under 5% wrong fuel contamination. Keep in mind that it is infrequent - certainly not impossible to encounter. You can get a number of motor vehicles that don't endure any quantity of contamination at all.
    2. Anywhere between 3.5 and 7 litres of Diesel in the Subaru (from 5 to 10%) is really a 50/50 condition. Our experience demonstrates that as many motorists get away with it as all those who break down. Whenever you are deciding on whether or not to risk it and just simply top it up consider that it is exactly like wagering everything on black - you will have a 50/50 chance of it working.
    3. Anything in excess of 7 litres of Diesel in your Petrol SVx really should immediately be removed seeing that your probability of driving with that level of contamination is certainly less than one in fifty - extremely big odds.
  2. Put some Diesel in a Petrol Subaru and drove it: Have you seen any performance difficulties as a result of putting the incorrect fuel in your SVx? If that's the case, get it drained irrespective of the quantity of Diesel or the contamination percentage. Continuing to drive running a car that is already beginning to suffer the effect of wrong fuel contamination will probably definitely cause more and more harm being caused to the fuel system.
  3. Are you looking for assurance?
    Simply get it drained. Whatever the contamination ratio, there is always some amount of risk in connection with driving a Petrol vehicle on Petrol contaminated with the wrong fuel. Likely implications of driving on the wrong fuel include the engine not starting, running unevenly, losing power, degradation of the high-pressure pump, damaged or clogged injectors, and so on. These are a few of the commonest Diesel in Petrol warning signs, and if you observe any of them stop driving and get it drained as soon as possible.

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.
