Volkswagen Fuel Drain


Putting Diesel in a Petrol Volkswagen is a well-known mistake to make. And its solution will depend on several different things. Assuming you would like to know what you should do about it then please read on.
Let us discuss the key factors to consider when making a decision whether or not to get a fuel drain:

  1. Exactly how much Diesel have you put in the Volkswagen, taking into account that the fuel tank capacity of your Volkswagen Caddy TSI is in most cases about 60 litres?
    1. A modest quantity of Diesel, something like 3 litres of Diesel in a Petrol Caddy TSI will in most situations not be a massive problem. Experience has taught us that anything less than 3 litres (approximately 5% of the whole fuel tank capacity) is very often able to be adequately diluted simply by thoroughly filling the remainder of the tank with the appropriate fuel.
      It's rather unusual to find a car suffering from issues due to below 5% wrong fuel contamination. Bear in mind that it is very infrequently found - in no way impossible to encounter. There are actually some automobiles that won't endure any quantity of contamination in the slightest.
    2. Between 3 and 6 litres of Diesel in the Volkswagen (5 to 10%) is really a 50/50 situation. Our expertise has shown us that as many drivers get away with it as those who break down. Whenever you are trying to decide whether to chance it and just simply fill it up consider that it is just like gambling your car on black - you have a 50/50 chance of it working out.
    3. Anything more than 6 litres of Diesel in your Petrol Caddy TSI ought to right away be drained out seeing that your likelihood of succeeding with this amount of contamination is more than likely less than one in fifty - really long odds.
  2. Put some Diesel in a Petrol Volkswagen and drove it: Have you noticed any performance difficulties after putting the incorrect fuel in the Caddy TSI? If you have, have it drained regardless of the amount of Diesel or the contamination percentage. Continuing to run running a vehicle that is already starting to suffer from the effects of fuel contamination will probably just end up in even more harm affecting your fuel system parts.
  3. Are you looking for reassurance?
    In that case get it drained. Regardless of the contamination percentage, there is always some degree of threat associated with running a Petrol vehicle on fuel contaminated with the wrong fuel. Likely outcomes of driving a car on the wrong fuel normally include the motor not starting, running unevenly, reduced power, degradation of the high-pressure pump, worn or bunged injectors, and so forth. These are several of the most common Diesel in Petrol warning signs, and in the event that you recognise any of them then stop and have it drained asap.

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.
