Volkswagen Fuel Drain


Filling Diesel in a Petrol Volkswagen is a well-known problem. And its solution is determined by various things. In case you would like to know what to do to fix it then keep reading.
Listed here the main variables to be aware of whenever determining whether or not to get the car drained:

  1. What level of Diesel did you put into the Volkswagen, bearing in mind that the fuel tank capacity of the Volkswagen Polo Fun is most likely about 45 litres?
    1. A modest quantity of Diesel, as little as 2.25 litres of Diesel in a Petrol Polo Fun will in most situations not really be a significant problem. Experience has proven to us that an amount less than 2.25 litres (which is almost 5% of the overall fuel tank volume) is generally able to be completely diluted through entirely topping up the rest of the tank with Petrol.
      It's quite unusual to come across a vehicle having difficulties due to under 5% wrong fuel contamination. Keep in mind it's uncommon - certainly not impossible to find. There are some motor vehicles that won't endure any level of contamination in the slightest.
    2. Between 2.25 and 4.5 litres of Diesel in the Volkswagen (from 5 to 10%) is a 50/50 situation. Our practical experience has confirmed that as many drivers get away with it as those who don't. Any time you're deciding whether to chance it and basically top it up bear in mind that it is the same thing as gambling all of it on black - you will have a 50/50 chance of it being ok.
    3. Anything more than 4.5 litres of Diesel in your Petrol Polo Fun should really immediately be drained seeing as your probability of getting away with that amount of contamination is more than likely less than one in fifty - definitely huge odds.
  2. Put some Diesel in a Petrol Volkswagen and drove it: Have you detected any performance concerns ever since putting the incorrect fuel in the Polo Fun? In that case, get it removed no matter the quantity of Diesel or even the contamination ratio. Continuing to drive running a vehicle that is beginning to suffer the effect of wrong fuel contamination will probably just result in increasing amounts of damage being done to your fuel system parts.
  3. Do you need reassurance?
    Simply get it drained. Whatever the contamination percentage, there is always a certain level of threat resulting from operating a Petrol motor on Petrol contaminated with Diesel. Probable implications of driving on the incorrect fuel can include the engine not starting, running lumpy, lack of power, degradation of the high-pressure pump, damaged or bunged injectors, etc. These are a few of the most frequently seen Diesel in Petrol signs or symptoms, and if you notice any of them then stop and have it drained as soon as possible.

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.
