Volkswagen Fuel Drain


Filling up with Petrol in a Diesel Volkswagen is a common mistake. And its solution varies according to a number of things. If perhaps you want to know what it is advisable to do to sort it out then keep reading.
Listed here are the most crucial variables to be aware of when determining whether or not to get a fuel drain:

  1. What amount of Petrol did you put into the Volkswagen, considering that the fuel tank capacity of your Volkswagen Vento TDI is in most cases approximately 55 litres?
    1. A tiny quantity of Petrol, something like 2.75 litres of Petrol in a Diesel Vento TDI will generally not be a massive problem. Experience has proven to us that an amount less than 2.75 litres (which is close to 5% of the overall fuel tank capacity) is in many instances able to be adequately diluted through thoroughly filling the remainder of the tank with Diesel.
      It is very uncommon to encounter an automobile having difficulties because of lower than 5% incorrect fuel contamination. Keep in mind it is rare - in no way impossible to find. There are some automobiles that don't stand any level of contamination whatsoever.
    2. Between 2.75 and 5.5 litres of Petrol in the Volkswagen (5 to 10%) is really a 50/50 situation. Our working experience demonstrates that as many motorists get away with it as all those who don't. Whenever deciding on whether to risk it and simply top it up consider that it is the same thing as wagering everything on black - you will have a 50/50 chance of it being ok.
    3. Anything in excess of 5.5 litres of Petrol in a Diesel Vento TDI should really promptly be drained seeing as your probability of getting away with that quantity of contamination is almost certainly lower than one in fifty - truly big odds.
  2. Put some Petrol in a Diesel Volkswagen and drove it: Have you observed any kind of performance troubles after putting the incorrect fuel in your Vento TDI? In that case, get it removed regardless of the amount of Petrol or the contamination ratio. Continuing to run running an automobile that is currently beginning to suffer from the consequences of fuel contamination can definitely be responsible for even more harm affecting your fuel system.
  3. Would you like reassurance?
    Simply get it removed. No matter the contamination ratio, there is invariably a certain level of threat resulting from running a Diesel vehicle on fuel contaminated with the wrong fuel. Likely results of driving a car on the wrong fuel include things like the motor refusing to start, running lumpy, lack of power, wearing of the high-pressure pump, worn or bunged injectors, and the like. These are a few of the most common Petrol in Diesel signs and symptoms, and in the event that you notice any of them then stop driving and get it removed right now.

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.
