Volkswagen Fuel Drain


Filling Diesel in a Petrol Volkswagen is a regularly occurring error. And its remedy varies according to an assortment of factors. If perhaps you would like to find out what you need to do about it then keep on reading.
Listed below are the most important variables to keep in mind when choosing whether to have a fuel drain:

  1. What amount of Diesel have you put in the Volkswagen, taking into account that the fuel tank capacity of the Volkswagen CC TSI is in most cases approximately 70 litres?
    1. A small amount of Diesel, as little as 3.5 litres of Diesel in a Petrol CC TSI will usually not really be a big problem. Experience has proven to us that anything less than 3.5 litres (almost 5% of the fuel tank volume) is often capable of being adequately diluted by means of thoroughly filling the remainder of the tank with the appropriate fuel.
      It's pretty unusual to find a car going through difficulties because of lower than 5% incorrect fuel contamination. Be aware that it's rare - certainly not impossible to encounter. You will discover some automobiles that don't stand any amount of fuel contamination whatsoever.
    2. Between 3.5 and 7 litres of Diesel in the Volkswagen (from 5 to 10%) is really a 50/50 condition. Our practical experience demonstrates that as many people get away with it as all those who break down. Whenever you are deciding upon whether or not to risk it and just simply top it up bear in mind that it is much like gambling everything on black - you have a 50/50 possibility of it working out.
    3. Anything above 7 litres of Diesel in a Petrol CC TSI should really immediately be drained seeing that your probability of getting away with this level of contamination is more than likely below one in fifty - seriously huge odds.
  2. Put some Diesel in a Petrol Volkswagen and drove it: Have you detected any kind of performance difficulties since putting the wrong fuel in the CC TSI? If you have, get it drained regardless of the volume of Diesel or the contamination ratio. Continually running a vehicle that is currently beginning to suffer from the effects of wrong fuel contamination will likely lead to progressively more harm being caused to your fuel system components.
  3. Do you want security?
    You should get it emptied. Regardless of contamination percentage, there is invariably some extent of threat in connection with driving a Petrol motor on Petrol contaminated with the incorrect fuel. Probable outcomes of driving a car on the incorrect fuel normally include the motor refusing to start, running unevenly, loss in power, degradation of the high-pressure pump, damaged or clogged injectors, etc. These are a few of the most frequently seen Diesel in Petrol symptoms, and in the event that you recognise any of them cease driving and have it drained right away.

Diesel in Petrol FAQs

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.
