Volkswagen Fuel Drain


Putting Petrol in a Diesel Volkswagen is a common error. And what you want to do about it depends upon an assortment of factors. In case you would like to find out what you have to do about it then read on.
Listed here are the most crucial factors to consider when deciding whether or not to have a fuel drain:

  1. What amount of Petrol did you put in the Volkswagen, keeping in mind that the fuel capacity of the Volkswagen CC TDI is usually approximately 70 litres?
    1. A small quantity of Petrol, something like 3.5 litres of Petrol in a Diesel CC TDI will in most situations not be a massive problem. Experience has proven to us that an amount less than 3.5 litres (which is roughly 5% of the total fuel tank) is in many instances capable of being completely diluted by means of thoroughly topping up the remainder of the tank with Diesel.
      It is pretty unusual to come across a vehicle suffering from problems because of below 5% incorrect fuel contamination. Remember that it's unusual - in no way impossible to encounter. You will discover a few vehicles that will not stand any degree of contamination in the slightest.
    2. Between 3.5 and 7 litres of Petrol in the Volkswagen (from 5 to 10%) is more of a 50/50 situation. Our working experience demonstrates that as many people get away with this as those people who break down. Whenever deciding whether to risk it and basically fill it up recognise that it is much like gambling everything on black - you will have a 50/50 chance of it working.
    3. Anything in excess of 7 litres of Petrol in a Diesel CC TDI really should straight away be drained seeing as your probability of driving with that amount of contamination is probably lower than one in fifty - seriously long odds.
  2. Put Petrol in a Diesel Volkswagen and drove it: Have you spotted any kind of performance issues since putting the bad fuel in your CC TDI? If you have, get it removed regardless of the quantity of Petrol or even the contamination percentage. Still running a car that is beginning to suffer the effect of wrong fuel contamination can only end up in even more harm being caused to the fuel system parts.
  3. Do you need reassurance?
    In that case get it drained. Regardless of the contamination ratio, there is always some amount of threat caused by driving a Diesel motor on Diesel contaminated with Petrol. Probable consequences of driving a vehicle on the incorrect fuel normally include the motor not starting, running unevenly, decrease in power, wearing of the high-pressure pump, worn out or blocked injectors, etc. These are a few of the commonest Petrol in Diesel signs and symptoms, and should you detect any of them cease driving and have it removed 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.
