Volkswagen Fuel Drain


Filling up with Petrol in a Diesel Volkswagen is a regularly occurring problem. And its remedy hinges on several things. If you want to find out what it is best to do to sort it out then please read on.
Listed here the most crucial factors to to consider whenever deciding on whether to get a fuel drain:

  1. How much Petrol did you put into the Volkswagen, taking into consideration that the fuel tank capacity of the Volkswagen Jetta TDI is in most cases roughly 55 litres?
    1. A modest amount of Petrol, something like 2.75 litres of Petrol in a Diesel Jetta TDI will usually not be a significant problem. Experience has shown us that an amount under 2.75 litres (almost 5% of the whole fuel tank volume) is frequently able to be completely diluted simply by thoroughly topping the remainder of the tank with Diesel.
      It is pretty uncommon to encounter a car suffering from problems because of below 5% incorrect fuel contamination. Remember that it is very unusual - not impossible to find. You can get some cars that will not stand any level of contamination in the slightest.
    2. Between 2.75 and 5.5 litres of Petrol in the Volkswagen (from 5 to 10%) is a 50/50 condition. Our working experience has shown that as many people get away with it as those who break down. Whenever you are figuring out whether to chance it and just fill it up bear in mind that it is much like betting your car on black - you will have a 50/50 possibility of it working.
    3. Anything over 5.5 litres of Petrol in a Diesel Jetta TDI really should immediately be drained since your likelihood of driving with this amount of contamination is certainly lower than one in 50 - really huge odds.
  2. Put some Petrol in a Diesel Volkswagen and drove it: Have you observed any kind of performance difficulties as a result of putting the incorrect fuel in your Jetta TDI? If you have, have it emptied irrespective of the volume of Petrol or even the contamination percentage. Still running a vehicle that is currently starting to suffer the effect of wrong fuel contamination can just be responsible for even more harm being done to the fuel system parts.
  3. Are you looking for peace of mind?
    You should get it drained. Regardless of contamination percentage, there is always some amount of danger affiliated with driving a Diesel motor on fuel contaminated with Petrol. Probable outcomes of driving a vehicle on the wrong fuel can include the motor not starting, running lumpy, decrease in power, degradation of the high-pressure pump, worn or blocked injectors, and so on. These are a few of the commonest Petrol in Diesel signs and symptoms, and if you observe any of them then cease driving 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.
