Volkswagen Fuel Drain


Filling up with Petrol in a Diesel Volkswagen is a regularly occurring mistake. And its remedy depends upon several different things. In case you want to know what it is advisable to do to fix it then please read on.
These are the main factors to take into consideration when figuring out whether or not to have your car drained:

  1. What amount of Petrol did you put into the Volkswagen, considering that the fuel capacity of the Volkswagen Lupo TDI is probably roughly 34 litres?
    1. A small amount of Petrol, less than 1.7 litres of Petrol in a Diesel Lupo TDI will usually not really be a significant problem. Experience has shown us that quantities under 1.7 litres (which is roughly 5% of the fuel tank volume) is in many instances capable of being adequately diluted simply by entirely filling the remainder of the tank with Diesel.
      It is quite rare to come across a vehicle having problems with less than 5% incorrect fuel contamination. Keep in mind that it is very infrequent - in no way impossible to find. There are actually a number of motor vehicles that don't stand any level of fuel contamination at all.
    2. Somewhere between 1.7 and 3.4 litres of Petrol in the Volkswagen (from 5 to 10%) is a 50/50 scenario. Our experience has shown that as many motorists get away with it as those people who break down. When figuring out whether or not to risk it and basically top it up recognise that it is much like wagering all of it on black - you will have a 50/50 possibility of it working.
    3. Anything more than 3.4 litres of Petrol in a Diesel Lupo TDI must straightaway be drained out since your probability of driving with that quantity of contamination is very likely less than one in 50 - genuinely long odds.
  2. Put Petrol in a Diesel Volkswagen and drove it: Have you noted any kind of performance issues since putting the incorrect fuel in your Lupo TDI? In that case, get it drained no matter the quantity of Petrol or the contamination percentage. Continually driving a motor vehicle that is currently beginning to suffer the consequences of wrong fuel contamination can typically bring about more harm affecting the fuel system parts.
  3. Do you want peace of mind?
    Then simply just get it removed. No matter the contamination percentage, there is inevitably some extent of risk in connection with driving a Diesel engine on fuel contaminated with the incorrect fuel. Probable final outcomes of driving a vehicle on the wrong fuel can include the motor not starting, running lumpy, loss in power, wearing of the high-pressure pump, worn or bunged injectors, and so on. These are several of the commonest Petrol in Diesel signs or symptoms, and in the event that you observe any of them cease driving and have it removed right away.

Petrol in Diesel FAQs

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
