Volvo Fuel Drain


Putting Diesel in a Petrol Volvo is a usual mistake to make. And its remedy is based on various things. In case you want to find out what you need to do to sort it out then stay with me.
These are the most important variables to think about whenever determining whether or not to have a fuel drain:

  1. How much Diesel have you put into the Volvo, keeping in mind that the fuel capacity of your Volvo C30 is normally around 55 litres?
    1. A tiny quantity of Diesel, less than 2.75 litres of Diesel in a Petrol C30 will in most cases not be a huge problem. Experience has proven to us that anything under 2.75 litres (which is close to 5% of the fuel tank volume) is usually capable of being completely diluted by means of totally filling the remainder of the tank with the appropriate fuel.
      It is very rare to come across a car or truck suffering from problems with lower than 5% incorrect fuel contamination. Please remember it is very rare - not impossible to encounter. You can get some vehicles that won't stand any amount of contamination at all.
    2. Somewhere between 2.75 and 5.5 litres of Diesel in the Volvo (from 5 to 10%) is more of a 50/50 scenario. Our experience has demonstrated that as many people get away with this as all those who break down. Any time you're figuring out whether to chance it and simply top it up consider that it is exactly like betting it all on black - you will have a 50/50 possibility of it working out.
    3. Anything over 5.5 litres of Diesel in your Petrol C30 should really straightaway be removed since your probability of getting away with that amount of contamination is almost certainly below one in fifty - truly big odds.
  2. Put Diesel in a Petrol Volvo and drove it: Have you noted any performance problems as a result of putting the bad fuel in your C30? If you have, have it drained no matter the volume of Diesel or even the contamination ratio. Proceeding to run driving a motor vehicle that is beginning to suffer the effect of wrong fuel contamination will probably only lead to even more harm affecting the fuel system.
  3. Would you like peace of mind?
    Simply get it drained. Whatever the contamination percentage, there is inevitably a certain level of danger linked with operating a Petrol vehicle on Petrol contaminated with the wrong fuel. Possible results of driving on the wrong fuel include the engine not starting, running lumpy, reduced power, wearing of the high-pressure pump, worn out or blocked injectors, and the like. These are some of the commonest Diesel in Petrol symptoms, and in the event that you recognise any of them stop driving 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.
