Audi Fuel Drain


Putting Diesel in a Petrol Audi is a regularly occurring mistake to make. And its remedy depends upon various factors. In case you want to find out what it is best to do to fix it then read on.
Listed below are the most important factors to consider whenever figuring out whether to have a fuel drain:

  1. Exactly how much Diesel did you put into the Audi, taking into account that the fuel tank capacity of your Audi RS6 Quattro is most likely around 70 litres?
    1. A small quantity of Diesel, as little as 3.5 litres of Diesel in a Petrol RS6 Quattro will usually not necessarily be a massive problem. Experience has demonstrated to us that quantities under 3.5 litres (which is approximately 5% of the whole fuel tank volume) is sometimes capable of being completely diluted simply by entirely filling the tank with Petrol.
      It is quite uncommon to find a motor vehicle suffering from difficulties due to lower than 5% wrong fuel contamination. Remember that it is rare - certainly not impossible to find. There are actually certain motor vehicles that will not endure any quantity of fuel contamination whatsoever.
    2. Somewhere between 3.5 and 7 litres of Diesel in the Audi (from 5 to 10%) is more of a 50/50 scenario. Our practical experience has demonstrated that as many people get away with this as those people who break down. Any time you're deciding upon whether to chance it and just simply fill it up consider that it is very much like betting it all on black - you have a 50/50 possibility of it working out.
    3. Anything in excess of 7 litres of Diesel in a Petrol RS6 Quattro should straightaway be removed as your likelihood of getting away with this amount of contamination is in all likelihood lower than one in fifty - truly huge odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you seen any kind of performance problems ever since putting the incorrect fuel in your RS6 Quattro? If that's the case, have it removed no matter the amount of Diesel or the contamination ratio. Continually running a car that is now beginning to suffer from the effects of wrong fuel contamination can definitely end up in progressively more damage affecting your fuel system.
  3. Are you interested in security?
    Simply get it emptied. Regardless of the contamination ratio, there is always a certain level of threat connected with running a Petrol motor on Petrol contaminated with Diesel. Likely outcomes of driving on the wrong fuel normally include the motor not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn or bunged injectors, and so forth. These are some of the most frequently seen Diesel in Petrol warning signs, and should you recognise any of them stop driving and get it removed right away.

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.
