Volkswagen Fuel Drain


Filling up with Petrol in a Diesel Volkswagen is a regularly occurring mistake to make. And what you should do about it hinges on various factors. In case you want to know what to do to sort it out then keep reading.
Let us discuss the key factors to think about whenever making a decision whether or not to have a fuel drain:

  1. How much Petrol have you put into the Volkswagen, taking into consideration that the fuel tank capacity of the Volkswagen Bora TDI is normally roughly 55 litres?
    1. A small amount of Petrol, something like 2.75 litres of Petrol in a Diesel Bora TDI will in most situations not be a massive problem. Experience has demonstrated to us that anything less than 2.75 litres (5% of the fuel tank) is frequently capable of being completely diluted by means of entirely filling up the tank with Diesel.
      It is extremely rare to come across a car going through problems due to under 5% wrong fuel contamination. Please remember it is very infrequently found - not impossible to encounter. There are some motor vehicles that won't stand any amount of fuel contamination in the slightest.
    2. Somewhere between 2.75 and 5.5 litres of Petrol in the Volkswagen (5 to 10%) is a 50/50 situation. Our practical experience has demonstrated that as many people get away with it as those people who break down. When deciding whether or not to risk it and simply fill it up remember that it is much like betting all of it on black - you've got a 50/50 chance of it being ok.
    3. Anything above 5.5 litres of Petrol in a Diesel Bora TDI should straightaway be drained out as your probability of driving with this quantity of contamination is certainly less than one in 50 - extremely long odds.
  2. Put Petrol in a Diesel Volkswagen and drove it: Have you observed any performance concerns as a result of putting the wrong fuel in your Bora TDI? If so, get it emptied no matter the quantity of Petrol or even the contamination ratio. Continuing to drive driving a car that is now beginning to suffer the effects of wrong fuel contamination will just bring about increasing amounts of damage being caused to your fuel system components.
  3. Are you interested in reassurance?
    Then get it drained. Regardless of the contamination ratio, there is always some extent of risk in connection with operating a Diesel motor on fuel contaminated with Petrol. Probable consequences of driving on the incorrect fuel normally include the engine refusing to start, running lumpy, decrease in power, wearing of the high-pressure pump, damaged or clogged injectors, etc. These are a few of the most common Petrol in Diesel symptoms, and should you detect any of them stop and have it drained as soon as possible.

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.
