Volvo Fuel Drain


Putting Petrol in a Diesel Volvo is a common mistake. And what you need to do about it hinges on various things. In the event that you want to know what you ought to do about it then keep on reading.
Right here are the most crucial variables to take into consideration when deciding whether to have the car drained:

  1. What amount of Petrol did you put in the Volvo, taking into account that the fuel capacity of your Volvo 850 TDI is normally about 73 litres?
    1. A modest quantity of Petrol, as little as 3.65 litres of Petrol in a Diesel 850 TDI will most of the time not necessarily be a major problem. Experience has proven to us that quantities less than 3.65 litres (roughly 5% of the whole fuel tank) is oftentimes able to be completely diluted simply by totally topping the tank with Diesel.
      It is quite unusual to come across a car having problems with under 5% incorrect fuel contamination. Remember that it is rare - not impossible to find. You can get some cars that will not stand any level of contamination at all.
    2. Anywhere between 3.65 and 7.3 litres of Petrol in the Volvo (from 5 to 10%) is more of a 50/50 condition. Our practical experience has shown us that as many people get away with this as all those who break down. Any time you are figuring out whether or not to chance it and basically fill it up remember that it is very much like wagering all of it on black - you have got a 50/50 possibility of it working.
    3. Anything over 7.3 litres of Petrol in a Diesel 850 TDI really should promptly be removed seeing that your likelihood of getting away with this level of contamination is more than likely less than one in fifty - seriously huge odds.
  2. Put Petrol in a Diesel Volvo and drove it: Have you noticed any performance problems ever since putting the wrong fuel in the 850 TDI? If so, get it drained irrespective of the amount of Petrol or even the contamination percentage. Continuing to drive running a motor vehicle that is now beginning to suffer from the effect of fuel contamination will probably likely end up in even more harm being caused to the fuel system components.
  3. Do you need security?
    Simply get it removed. No matter the contamination percentage, there is always some amount of threat in connection with operating a Diesel engine on fuel contaminated with the wrong fuel. Likely final outcomes of driving a car on the wrong fuel can include the engine refusing to start, running lumpy, decrease in power, wearing of the high-pressure pump, worn or bunged injectors, and the like. These are a few of the most common Petrol in Diesel symptoms, and in the event that you notice any of them then stop and have it drained right now.

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.
