Volvo Fuel Drain


Filling up with Diesel in a Petrol Volvo is a fairly typical mistake to make. And its solution depends upon various things. If perhaps you would like to find out what you have to do to fix it then continue reading.
Here are the most important variables to consider when deciding whether or not to have the car drained:

  1. What level of Diesel have you put in the Volvo, taking into account that the fuel tank capacity of your Volvo 850 is probably about 73 litres?
    1. A modest quantity of Diesel, less than 3.65 litres of Diesel in a Petrol 850 will in most situations not really be a massive problem. Experience has taught us that quantities under 3.65 litres (which is about 5% of the total fuel tank) is quite often capable of being adequately diluted by completely topping up the remainder of the tank with Petrol.
      It is extremely uncommon to come across a motor vehicle having difficulties with under 5% incorrect fuel contamination. Bear in mind that it is very rare - definitely not impossible to find. There are actually a number of vehicles that will not stand any level of fuel contamination whatsoever.
    2. Somewhere between 3.65 and 7.3 litres of Diesel in the Volvo (5 to 10%) is more of a 50/50 condition. Our experience has revealed that as many motorists get away with it as those people who don't. When you are deciding upon whether or not to chance it and simply fill it up bear in mind that it is the same thing as wagering everything on black - you've got a 50/50 possibility of it being ok.
    3. Anything over 7.3 litres of Diesel in your Petrol 850 must straight away be drained seeing that your probability of succeeding with this amount of contamination is undoubtedly lower than one in fifty - truly long odds.
  2. Put some Diesel in a Petrol Volvo and drove it: Have you noticed any kind of performance concerns as a result of putting the incorrect fuel in the 850? In that case, get it emptied no matter the quantity of Diesel or the contamination percentage. Proceeding to run running a car that is already beginning to suffer from the effects of wrong fuel contamination will probably definitely lead to increasing amounts of harm being caused to your fuel system parts.
  3. Do you need security?
    Simply get it removed. Regardless of contamination ratio, there is inevitably some amount of threat connected with operating a Petrol motor on fuel contaminated with Diesel. Likely outcomes of driving on the incorrect fuel include the motor refusing to start, running unevenly, loss in power, degradation of the high-pressure pump, worn or blocked injectors, and so on. These are several of the most frequently seen Diesel in Petrol signs and symptoms, and in the event that you notice any of them stop driving and have it drained asap.

Diesel in Petrol Questions

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.
