Volkswagen Fuel Drain


Filling Petrol in a Diesel Volkswagen is a common error. And exactly what you need to do about it depends on a few factors. In the event that you want to find out what it is advisable to do about it then keep on reading.
Listed here are the key variables to take into consideration whenever choosing whether to get it drained:

  1. Exactly how much Petrol have you put in the Volkswagen, bearing in mind that the fuel capacity of your Volkswagen Tiguan TDI is in most cases roughly 64 litres?
    1. A tiny quantity of Petrol, as little as 3.2 litres of Petrol in a Diesel Tiguan TDI will in most situations not be a significant problem. Experience has demonstrated to us that anything under 3.2 litres (approximately 5% of the fuel tank) is sometimes capable of being adequately diluted through entirely topping the tank with Diesel.
      It is rather uncommon to find an automobile experiencing issues due to lower than 5% incorrect fuel contamination. Keep in mind that it's unusual - certainly not impossible to encounter. You can get a number of automobiles that don't endure any quantity of fuel contamination whatsoever.
    2. Anywhere between 3.2 and 6.4 litres of Petrol in the Volkswagen (5 to 10%) is really a 50/50 scenario. Our expertise has confirmed that as many motorists get away with this as those who break down. When deciding upon whether or not to risk it and just fill it up consider that it is much like betting everything on black - you've got a 50/50 possibility of it being ok.
    3. Anything above 6.4 litres of Petrol in your Diesel Tiguan TDI should immediately be drained out since your probability of getting away with this amount of contamination is more than likely below one in fifty - truly long odds.
  2. Put some Petrol in a Diesel Volkswagen and drove it: Have you noted any performance troubles since putting the wrong fuel in the Tiguan TDI? If so, have it emptied regardless of the amount of Petrol or even the contamination percentage. Continuing to run driving a motor vehicle that is already starting to suffer from the effects of wrong fuel contamination will probably just bring about more harm being done to the fuel system components.
  3. Are you interested in reassurance?
    Then get it emptied. Whatever the contamination ratio, there is invariably some extent of threat in connection with running a Diesel motor on Diesel contaminated with Petrol. Likely consequences of driving a car on the incorrect fuel can include the motor not starting, running lumpy, lack of power, wearing of the high-pressure pump, damaged or clogged injectors, etc. These are several of the most typical Petrol in Diesel signs or symptoms, and if you notice any of them stop driving and have it removed asap.

Petrol in Diesel FAQs

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.
