Volkswagen Fuel Drain


Filling Diesel in a Petrol Volkswagen is a fairly typical mistake. And exactly what you have to do about it is based on several different factors. In case you would like to find out what it is advisable to do to sort it out then stay with me.
Let us discuss the most important factors to take into account when deciding on whether to get a fuel drain:

  1. How much Diesel have you put in the Volkswagen, bearing in mind that the fuel tank capacity of the Volkswagen Lupo is most likely around 34 litres?
    1. A small amount of Diesel, something like 1.7 litres of Diesel in a Petrol Lupo will typically not really be a significant problem. Experience has demonstrated to us that an amount less than 1.7 litres (5% of the fuel tank volume) is very often capable of being adequately diluted through entirely filling the tank with Petrol.
      It is rather rare to come across a car or truck suffering from problems with lower than 5% incorrect fuel contamination. Bear in mind that it's infrequently found - in no way impossible to encounter. You can get a few motor vehicles that won't stand any degree of fuel contamination in the slightest.
    2. Anywhere between 1.7 and 3.4 litres of Diesel in the Volkswagen (5 to 10%) is more of a 50/50 situation. Our working experience has proven that as many drivers get away with it as those who break down. Any time you're deciding upon whether or not to risk it and simply top it up recognise that it is very much like wagering everything on black - you've got a 50/50 chance of it working.
    3. Anything in excess of 3.4 litres of Diesel in your Petrol Lupo really should immediately be drained out seeing as your likelihood of getting away with that quantity of contamination is more than likely less than one in 50 - definitely long odds.
  2. Put some Diesel in a Petrol Volkswagen and drove it: Have you observed any performance difficulties as a result of putting the wrong fuel in the Lupo? If so, get it emptied irrespective of the volume of Diesel or the contamination percentage. Continually running a motor vehicle that is already starting to suffer the consequences of wrong fuel contamination will probably definitely be responsible for increasing amounts of damage being done to the fuel system components.
  3. Are you looking for reassurance?
    Then simply just get it removed. No matter the contamination percentage, there is inevitably some extent of threat resulting from operating a Petrol motor on fuel contaminated with the wrong fuel. Likely implications of driving on the incorrect fuel include things like the motor refusing to start, running lumpy, decrease in power, wearing of the high-pressure pump, worn out or clogged injectors, and so on. These are some of the most typical Diesel in Petrol warning signs, and in the event that you observe any of them then cease driving and have it drained right now.

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.
