Volvo Fuel Drain


Filling Petrol in a Diesel Volvo is a common error. And what you need to do about it will depend on several different factors. In case you would like to find out what to do to sort it out then read on.
Listed here the most important variables to think about when making a decision whether or not to have your car drained:

  1. What level of Petrol have you put in the Volvo, considering that the fuel capacity of the Volvo S40D is in most cases approximately 55 litres?
    1. A modest quantity of Petrol, less than 2.75 litres of Petrol in a Diesel S40D will in most situations not be a significant problem. Experience has shown us that an amount less than 2.75 litres (which is about 5% of the entire fuel tank volume) is oftentimes capable of being sufficiently diluted by means of completely topping the remainder of the tank with Diesel.
      It's relatively uncommon to find a car going through problems because of less than 5% wrong fuel contamination. Be aware that it is very uncommon - certainly not impossible to encounter. There are a number of motor vehicles that don't stand any degree of contamination in the slightest.
    2. Between 2.75 and 5.5 litres of Petrol in the Volvo (5 to 10%) is really a 50/50 condition. Our experience has revealed that as many motorists get away with it as those who break down. Whenever you are figuring out whether or not to risk it and just top it up remember that it is exactly like gambling it all on black - you have a 50/50 possibility of it working.
    3. Anything over 5.5 litres of Petrol in a Diesel S40D ought to straight away be removed because your likelihood of getting away with this amount of contamination is undoubtedly lower than one in fifty - extremely long odds.
  2. Put Petrol in a Diesel Volvo and drove it: Have you observed any performance troubles after putting the bad fuel in your S40D? If that's the case, have it removed no matter the volume of Petrol or the contamination percentage. Still driving a car that is beginning to suffer from the effect of fuel contamination can only bring about even more harm affecting the fuel system components.
  3. Would you like peace of mind?
    In that case get it removed. No matter the contamination ratio, there is always some extent of danger caused by driving a Diesel engine on fuel contaminated with Petrol. Possible final outcomes of driving a car on the incorrect fuel normally include the motor refusing to start, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or clogged injectors, etc. These are a few of the most typical Petrol in Diesel signs or symptoms, and if you observe any of them then stop and get it removed as soon as possible.

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.
