Volkswagen Fuel Drain


Filling Diesel in a Petrol Volkswagen is a common mistake. And exactly what you should do about it is dependent upon a number of things. If you want to find out what you must do about it then continue reading.
Listed below are the most important factors to to consider when figuring out whether or not to have your car drained:

  1. What level of Diesel did you put in the Volkswagen, keeping in mind that the fuel tank capacity of the Volkswagen Tiguan TSI is normally approximately 64 litres?
    1. Hardly any Diesel, something like 3.2 litres of Diesel in a Petrol Tiguan TSI will in most cases not really be a huge problem. Experience has taught us that quantities less than 3.2 litres (close to 5% of the overall fuel tank capacity) is quite often capable of being completely diluted simply by thoroughly filling the tank with the appropriate fuel.
      It is rather uncommon to come across a car or truck having difficulties because of below 5% wrong fuel contamination. Do not forget that it is unusual - in no way impossible to encounter. There are certain vehicles that don't endure any amount of fuel contamination at all.
    2. Anywhere between 3.2 and 6.4 litres of Diesel in the Volkswagen (5 to 10%) is really a 50/50 condition. Our practical experience has confirmed that as many drivers get away with this as those people who break down. Any time you are deciding on whether to chance it and just simply fill it up recognise that it is just like betting everything on black - you've got a 50/50 possibility of it working.
    3. Anything above 6.4 litres of Diesel in a Petrol Tiguan TSI ought to straight away be drained out as your probability of driving with this level of contamination is more than likely lower than one in 50 - genuinely long odds.
  2. Put Diesel in a Petrol Volkswagen and drove it: Have you noted any kind of performance concerns ever since putting the wrong fuel in your Tiguan TSI? If that's the case, get it removed regardless of the quantity of Diesel or the contamination ratio. Still running a vehicle that is currently beginning to suffer the effects of wrong fuel contamination can only lead to progressively more harm being caused to your fuel system components.
  3. Would you like security?
    Then get it emptied. No matter the contamination percentage, there is always some degree of risk associated with driving a Petrol motor on Petrol contaminated with Diesel. Possible consequences of driving on the wrong fuel normally include the motor refusing to start, running lumpy, losing power, wearing of the high-pressure pump, damaged or bunged injectors, and so forth. These are several of the most typical Diesel in Petrol signs or symptoms, and if you notice any of them then stop 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.
