Volkswagen Fuel Drain


Filling up with Diesel in a Petrol Volkswagen is a fairly typical mistake to make. And its remedy is dependent upon various factors. If you want to find out what you should do to fix it then please read on.
Listed below are the most important variables to take into account when determining whether or not to have a fuel drain:

  1. What level of Diesel did you put in to the Volkswagen, bearing in mind that the fuel tank capacity of the Volkswagen Touran TSI is probably about 60 litres?
    1. A small amount of Diesel, as little as 3 litres of Diesel in a Petrol Touran TSI will more often than not not necessarily be a significant problem. Experience has taught us that quantities under 3 litres (which is roughly 5% of the overall fuel tank) is in many instances able to be sufficiently diluted by means of thoroughly topping the remainder of the tank with the correct fuel.
      It's very rare to find an automobile going through difficulties due to lower than 5% incorrect fuel contamination. Please remember it is very rare - in no way impossible to find. You can get certain automobiles that won't endure any degree of fuel contamination at all.
    2. Between 3 and 6 litres of Diesel in the Volkswagen (from 5 to 10%) is a 50/50 situation. Our expertise has shown us that as many drivers get away with this as all those who don't. When deciding whether or not to risk it and basically top it up remember that it is very much like gambling all of it on black - you will have a 50/50 chance of it being ok.
    3. Anything above 6 litres of Diesel in a Petrol Touran TSI should really right away be drained out because your likelihood of driving with this amount of contamination is almost certainly below one in fifty - extremely long odds.
  2. Put Diesel in a Petrol Volkswagen and drove it: Have you detected any performance concerns ever since putting the wrong fuel in the Touran TSI? In that case, get it removed irrespective of the volume of Diesel or even the contamination percentage. Continuing to run driving an automobile that is now beginning to suffer the effects of wrong fuel contamination will probably likely cause progressively more harm being caused to your fuel system parts.
  3. Are you interested in security?
    Then get it drained. No matter the contamination ratio, there is inevitably a certain level of threat in connection with driving a Petrol engine on fuel contaminated with the incorrect fuel. Probable outcomes of driving on the incorrect fuel can include the motor refusing to start, running lumpy, reduced power, degradation of the high-pressure pump, damaged or blocked injectors, and so on. These are a few of the most frequently seen Diesel in Petrol signs or symptoms, and if you recognise any of them stop driving and get it removed as soon as possible.

Refrain from having any unqualified mechanic to attend your automobile. We are Volkswagen experts and possess the certification and knowledge required to make certain you are back on the road with little hassle or worry.

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.
