Mitsubishi Fuel Drain


Putting Diesel in a Petrol Mitsubishi is a well-known mistake. And what you have to do about it varies according to various factors. If you would like to know what you should do about this then stay with me.
Let us discuss the key variables to be aware of when determining whether to get a fuel drain:

  1. What level of Diesel have you put into the Mitsubishi, taking into consideration that the fuel capacity of your Mitsubishi Asx is most likely around 63 litres?
    1. A tiny quantity of Diesel, something like 3.15 litres of Diesel in a Petrol Asx will generally not necessarily be a big problem. Experience has proven to us that an amount under 3.15 litres (which is about 5% of the whole fuel tank) is very often able to be completely diluted simply by totally filling the remainder of the tank with the correct fuel.
      It is highly unusual to come across a car going through difficulties because of lower than 5% wrong fuel contamination. Please remember it's uncommon - not impossible to encounter. There are actually some motor vehicles that don't endure any quantity of fuel contamination at all.
    2. Between 3.15 and 6.3 litres of Diesel in the Mitsubishi (from 5 to 10%) is really a 50/50 condition. Our working experience has shown us that as many motorists get away with it as those who don't. Whenever you are figuring out whether to risk it and basically fill it up recognise that it is very much like wagering everything on black - you will have a 50/50 chance of it working out.
    3. Anything more than 6.3 litres of Diesel in a Petrol Asx really should immediately be drained seeing as your likelihood of getting away with that level of contamination is more than likely lower than one in fifty - really long odds.
  2. Put Diesel in a Petrol Mitsubishi and drove it: Have you spotted any kind of performance problems as a result of putting the incorrect fuel in your Asx? If you have, get it drained regardless of the quantity of Diesel or the contamination ratio. Still running a vehicle that is currently beginning to suffer from the consequences of fuel contamination will probably definitely bring about more damage affecting your fuel system.
  3. Would you like reassurance?
    You should get it emptied. Regardless of contamination ratio, there is inevitably some degree of risk in connection with driving a Petrol vehicle on Petrol contaminated with the incorrect fuel. Likely outcomes of driving on the wrong fuel include things like the engine refusing to start, running lumpy, losing power, wearing of the high-pressure pump, damaged or blocked injectors, etc. These are a few of the commonest Diesel in Petrol signs or symptoms, and if you notice any of them stop and have 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.
