Volkswagen Fuel Drain


Filling Diesel in a Petrol Volkswagen is a regular mistake. And its remedy will depend on a few things. In the event that you want to know what you need to do about it then continue reading.
Here are the key factors to think about whenever choosing whether to get a fuel drain:

  1. What level of Diesel did you put into the Volkswagen, taking into consideration that the fuel tank capacity of the Volkswagen Scirocco TSI is normally roughly 55 litres?
    1. A small quantity of Diesel, something like 2.75 litres of Diesel in a Petrol Scirocco TSI will normally not really be a major problem. Experience has shown us that an amount less than 2.75 litres (about 5% of the total fuel tank volume) is quite often capable of being completely diluted by wholly topping the remainder of the tank with Petrol.
      It is pretty unusual to find a vehicle going through issues with under 5% wrong fuel contamination. Bear in mind that it is infrequent - certainly not impossible to find. You can get some cars that don't endure any level of fuel contamination at all.
    2. Between 2.75 and 5.5 litres of Diesel in the Volkswagen (5 to 10%) is really a 50/50 scenario. Our practical experience demonstrates that as many motorists get away with it as all those who don't. Whenever you are figuring out whether or not to chance it and simply fill it up consider that it is just like gambling your car on black - you have a 50/50 chance of it working.
    3. Anything over 5.5 litres of Diesel in your Petrol Scirocco TSI must as soon as possible be removed seeing as your probability of driving with that amount of contamination is undoubtedly lower than one in 50 - definitely long odds.
  2. Put Diesel in a Petrol Volkswagen and drove it: Have you noted any performance difficulties since putting the wrong fuel in your Scirocco TSI? In that case, get it emptied no matter the volume of Diesel or the contamination percentage. Proceeding to drive driving a car that is now starting to suffer the effects of fuel contamination will definitely bring about even more harm affecting the fuel system parts.
  3. Would you like reassurance?
    Then simply just get it drained. No matter the contamination percentage, there is always some amount of danger connected with running a Petrol vehicle on Petrol contaminated with the wrong fuel. Likely outcomes of driving on the wrong fuel include the engine refusing to start, running lumpy, losing power, wearing of the high-pressure pump, damaged or blocked injectors, and so on. These are a few of the most common Diesel in Petrol signs and symptoms, and should you notice any of them then stop and have it removed 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.
