Volkswagen Fuel Drain


Filling up with Diesel in a Petrol Volkswagen is a fairly typical error. And exactly what you should do about it is based on a variety of things. If you would like to know what you should do to fix it then please read on.
These are the main variables to keep in mind whenever deciding on whether or not to have a fuel drain:

  1. What level of Diesel did you put in the Volkswagen, considering that the fuel capacity of the Volkswagen Up is in most cases approximately 35 litres?
    1. A tiny quantity of Diesel, as little as 1.75 litres of Diesel in a Petrol Up will quite often not really be a big problem. Experience has proven to us that an amount less than 1.75 litres (which is close to 5% of the whole fuel tank) is usually able to be adequately diluted by means of totally filling up the remainder of the tank with Petrol.
      It is rather unusual to find an automobile experiencing issues because of below 5% wrong fuel contamination. Be aware that it is infrequently found - not impossible to find. There are actually a few vehicles that won't stand any degree of contamination at all.
    2. Anywhere between 1.75 and 3.5 litres of Diesel in the Volkswagen (5 to 10%) is really a 50/50 situation. Our practical experience has shown us that as many motorists get away with this as those who don't. When figuring out whether or not to risk it and simply fill it up remember that it is the same thing as wagering your car on black - you've got a 50/50 possibility of it being ok.
    3. Anything above 3.5 litres of Diesel in your Petrol Up ought to as soon as possible be drained out as your likelihood of succeeding with this level of contamination is undoubtedly lower than one in 50 - truly long odds.
  2. Put Diesel in a Petrol Volkswagen and drove it: Have you seen any kind of performance problems since putting the wrong fuel in the Up? If that's the case, have it drained irrespective of the quantity of Diesel or the contamination percentage. Proceeding to run driving a car that is now beginning to suffer the effects of fuel contamination will likely result in increasing amounts of damage affecting the fuel system components.
  3. Would you like security?
    In that case get it removed. Regardless of contamination ratio, there is inevitably some amount of threat connected with operating a Petrol vehicle on fuel contaminated with Diesel. Probable consequences of driving on the incorrect fuel include things like the engine refusing to start, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or clogged injectors, etc. These are several of the commonest Diesel in Petrol signs or symptoms, and in the event that you notice any of them then stop and get it drained 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.
