Volkswagen Fuel Drain


Filling Diesel in a Petrol Volkswagen is a regular problem. And its solution is dependent upon various things. If perhaps you want to know what you need to do to fix it then keep reading.
These are the most important variables to consider whenever deciding on whether to have the car drained:

  1. What amount of Diesel have you put in the Volkswagen, taking into account that the fuel capacity of the Volkswagen Fox is most likely about 50 litres?
    1. A modest quantity of Diesel, less than 2.5 litres of Diesel in a Petrol Fox will most of the time not necessarily be a significant problem. Experience has taught us that an amount under 2.5 litres (which is almost 5% of the entire fuel tank capacity) is oftentimes capable of being completely diluted by means of totally filling up the remainder of the tank with the correct fuel.
      It's quite unusual to find a car experiencing problems with less than 5% incorrect fuel contamination. Bear in mind that it's unusual - in no way impossible to find. You can get some vehicles that will not stand any degree of fuel contamination in the slightest.
    2. In between 2.5 and 5 litres of Diesel in the Volkswagen (5 to 10%) is more of a 50/50 scenario. Our experience demonstrates that as many drivers get away with this as all those who break down. Any time you're trying to decide whether or not to risk it and just simply fill it up remember that it is much like wagering all of it on black - you have a 50/50 possibility of it working.
    3. Anything more than 5 litres of Diesel in a Petrol Fox should immediately be removed because your probability of succeeding with that quantity of contamination is certainly below one in fifty - truly huge odds.
  2. Put some Diesel in a Petrol Volkswagen and drove it: Have you spotted any performance difficulties since putting the incorrect fuel in your Fox? In that case, get it emptied no matter the volume of Diesel or even the contamination percentage. Continuing to run driving an automobile that is now starting to suffer from the effects of fuel contamination will only end up in even more harm being caused to the fuel system components.
  3. Do you want assurance?
    In that case get it removed. Regardless of the contamination percentage, there is always some extent of threat resulting from running a Petrol vehicle on Petrol contaminated with Diesel. Probable implications of driving on the wrong fuel normally include the motor refusing to start, running lumpy, reduced power, wearing of the high-pressure pump, worn out or blocked injectors, and so forth. These are some of the most common Diesel in Petrol signs and symptoms, and should you recognise any of them stop and get it removed right now.

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.
