Volkswagen Fuel Drain


Putting Diesel in a Petrol Volkswagen is a regular mistake to make. And exactly what you have to do about it will depend on several things. If you would like to find out what it is best to do about it then stay with me.
Listed here the most important factors to think about whenever deciding on whether to get it drained:

  1. What amount of Diesel did you put into the Volkswagen, bearing in mind that the fuel tank capacity of the Volkswagen Jetta TSI is in most cases about 55 litres?
    1. A modest amount of Diesel, something like 2.75 litres of Diesel in a Petrol Jetta TSI will more often than not not really be a huge problem. Experience has demonstrated to us that an amount less than 2.75 litres (which is approximately 5% of the total fuel tank capacity) is sometimes capable of being adequately diluted by means of totally topping the tank with the appropriate fuel.
      It is very rare to come across a car or truck experiencing difficulties because of under 5% wrong fuel contamination. Bear in mind that it's infrequent - in no way impossible to find. There are actually some vehicles that won't endure any level of fuel contamination whatsoever.
    2. Somewhere between 2.75 and 5.5 litres of Diesel in the Volkswagen (5 to 10%) is more of a 50/50 scenario. Our experience has revealed that as many people get away with it as those people who don't. When deciding on whether or not to risk it and just fill it up bear in mind that it is very much like gambling everything on black - you've got a 50/50 chance of it being ok.
    3. Anything above 5.5 litres of Diesel in a Petrol Jetta TSI really should immediately be drained out since your likelihood of driving with this level of contamination is probably less than one in 50 - definitely big odds.
  2. Put Diesel in a Petrol Volkswagen and drove it: Have you detected any performance concerns after putting the incorrect fuel in the Jetta TSI? If you have, have it removed no matter the volume of Diesel or even the contamination ratio. Continuing to run running a motor vehicle that is already beginning to suffer from the effects of wrong fuel contamination will typically result in increasing amounts of damage being done to the fuel system components.
  3. Are you interested in peace of mind?
    Then get it drained. Regardless of contamination ratio, there is invariably a certain level of risk connected to running a Petrol motor on fuel contaminated with the wrong fuel. Possible final outcomes of driving a car on the incorrect fuel include things like the engine not starting, running lumpy, losing power, degradation of the high-pressure pump, worn out or bunged injectors, and the like. These are a few of the most typical Diesel in Petrol warning signs, and if you notice any of them then stop driving and have it drained asap.

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.
