Volkswagen Fuel Drain


Filling up with Diesel in a Petrol Volkswagen is a fairly typical mistake to make. And exactly what you need to do about it will depend on a variety of factors. In case you would like to find out what you must do to sort it out then keep on reading.
Listed here the key factors to keep in mind when figuring out whether or not to have it drained:

  1. What amount of Diesel have you put into the Volkswagen, taking into consideration that the fuel capacity of the Volkswagen Vento is normally around 55 litres?
    1. A tiny amount of Diesel, something like 2.75 litres of Diesel in a Petrol Vento will in most situations not necessarily be a significant problem. Experience has taught us that anything less than 2.75 litres (which is almost 5% of the overall fuel tank capacity) is frequently able to be completely diluted simply by entirely topping the remainder of the tank with Petrol.
      It is pretty uncommon to come across a car experiencing issues due to less than 5% wrong fuel contamination. Please remember it is very rare - not impossible to encounter. There are actually some automobiles that won't endure any level of contamination whatsoever.
    2. Anywhere between 2.75 and 5.5 litres of Diesel in the Volkswagen (5 to 10%) is more of a 50/50 scenario. Our practical experience has shown that as many drivers get away with it as those people who break down. Any time you're trying to decide whether to chance it and simply top it up remember that it is just like gambling your car on black - you will have a 50/50 chance of it being ok.
    3. Anything above 5.5 litres of Diesel in your Petrol Vento must as soon as possible be drained out seeing as your probability of driving with that quantity of contamination is more than likely less than one in fifty - truly big odds.
  2. Put some Diesel in a Petrol Volkswagen and drove it: Have you spotted any kind of performance concerns since putting the wrong fuel in your Vento? If so, have it drained regardless of the amount of Diesel or the contamination ratio. Continually running a vehicle that is beginning to suffer from the effects of wrong fuel contamination can definitely cause even more damage affecting the fuel system parts.
  3. Do you need reassurance?
    Simply get it removed. Regardless of the contamination ratio, there is inevitably a certain level of threat connected with driving a Petrol vehicle on Petrol contaminated with Diesel. Likely implications of driving on the incorrect fuel include the engine refusing to start, running unevenly, losing power, wearing of the high-pressure pump, worn or clogged injectors, and the like. These are several of the commonest Diesel in Petrol signs or symptoms, and if you observe any of them stop and get it drained immediately.

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.
