Volkswagen Fuel Drain


Filling up with Petrol in a Diesel Volkswagen is a well-known mistake. And exactly what you should do about it is dependent upon several factors. In case you want to know what you must do about it then keep reading.
Listed below are the most important factors to keep in mind whenever determining whether or not to get your car drained:

  1. What level of Petrol did you put in to the Volkswagen, taking into consideration that the fuel capacity of the Volkswagen Caddy TDI is in most cases about 60 litres?
    1. A tiny quantity of Petrol, as little as 3 litres of Petrol in a Diesel Caddy TDI will generally not be a major problem. Experience has taught us that an amount under 3 litres (5% of the entire fuel tank capacity) is in many instances able to be sufficiently diluted through wholly topping the rest of the tank with Diesel.
      It is rather rare to come across a vehicle experiencing issues with lower than 5% wrong fuel contamination. Be aware that it is infrequently found - not impossible to encounter. You will discover a few cars that won't stand any quantity of fuel contamination in the slightest.
    2. In between 3 and 6 litres of Petrol in the Volkswagen (5 to 10%) is really a 50/50 condition. Our working experience has shown us that as many people get away with this as those who don't. When deciding whether or not to chance it and basically top it up recognise that it is the same thing as betting it all on black - you will have a 50/50 possibility of it working.
    3. Anything in excess of 6 litres of Petrol in a Diesel Caddy TDI really should as soon as possible be drained out because your likelihood of getting away with this amount of contamination is undoubtedly less than one in 50 - extremely huge odds.
  2. Put some Petrol in a Diesel Volkswagen and drove it: Have you observed any performance problems after putting the incorrect fuel in the Caddy TDI? If that's the case, have it drained irrespective of the quantity of Petrol or the contamination percentage. Continuing to drive driving a motor vehicle that is beginning to suffer from the consequences of fuel contamination can typically lead to more and more damage affecting the fuel system components.
  3. Would you like reassurance?
    You should get it removed. No matter the contamination ratio, there is always some degree of danger connected with operating a Diesel engine on fuel contaminated with the wrong fuel. Probable outcomes of driving on the wrong fuel normally include the motor refusing to start, running unevenly, decrease in power, wearing of the high-pressure pump, worn out or bunged injectors, etc. These are a few of the most typical Petrol in Diesel symptoms, and if you observe any of them then stop and have it removed asap.

Petrol in Diesel Questions

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.
