Volvo Fuel Drain


Putting Petrol in a Diesel Volvo is a well-known error. And exactly what you want to do about it hinges on an assortment of factors. Assuming you would like to find out what you must do to sort it out then keep on reading.
Let us discuss the key factors to to consider when choosing whether or not to get a fuel drain:

  1. Exactly how much Petrol did you put in the Volvo, considering that the fuel capacity of your Volvo V40 TD is most likely around 60 litres?
    1. A modest amount of Petrol, less than 3 litres of Petrol in a Diesel V40 TD will more often than not not necessarily be a big problem. Experience has proven to us that an amount under 3 litres (which is almost 5% of the total fuel tank volume) is in many instances able to be sufficiently diluted by means of completely topping the tank with Diesel.
      It is very uncommon to come across a vehicle having problems because of less than 5% incorrect fuel contamination. Remember that it's infrequently found - not impossible to encounter. There are a number of cars that don't endure any quantity of contamination in the slightest.
    2. In between 3 and 6 litres of Petrol in the Volvo (from 5 to 10%) is a 50/50 scenario. Our practical experience has revealed that as many drivers get away with it as all those who don't. Whenever trying to decide whether to risk it and simply fill it up consider that it is the same as gambling everything on black - you will have a 50/50 possibility of it being ok.
    3. Anything more than 6 litres of Petrol in your Diesel V40 TD really should straightaway be drained because your probability of succeeding with that quantity of contamination is in all likelihood lower than one in 50 - truly huge odds.
  2. Put some Petrol in a Diesel Volvo and drove it: Have you seen any performance difficulties ever since putting the incorrect fuel in the V40 TD? If that's the case, get it emptied irrespective of the amount of Petrol or the contamination percentage. Still driving a car that is currently beginning to suffer the effects of fuel contamination will typically end up in even more harm being caused to your fuel system.
  3. Do you want peace of mind?
    Then simply just get it emptied. Whatever the contamination ratio, there is always some degree of threat associated with operating a Diesel motor on fuel contaminated with the incorrect fuel. Probable results of driving on the wrong fuel include the engine refusing to start, running lumpy, loss in power, degradation of the high-pressure pump, worn or bunged injectors, and so forth. These are several of the most common Petrol in Diesel signs and symptoms, and in the event that you recognise any of them then stop and get it drained asap.

Petrol in Diesel FAQs

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.
