Audi Fuel Drain


Putting Diesel in a Petrol Audi is a regular mistake to make. And its remedy is dependent upon several things. In the event that you would like to find out what you ought to do to sort it out then read on.
Let us discuss the main variables to take into consideration whenever deciding on whether or not to get your car drained:

  1. How much Diesel have you put into the Audi, taking into consideration that the fuel capacity of your Audi R8Quattro is in most cases roughly 75 litres?
    1. A modest quantity of Diesel, as little as 3.75 litres of Diesel in a Petrol R8Quattro will in most situations not necessarily be a massive problem. Experience has demonstrated to us that anything less than 3.75 litres (approximately 5% of the whole fuel tank capacity) is oftentimes capable of being adequately diluted by completely filling up the tank with the correct fuel.
      It is highly rare to find a motor vehicle suffering from issues because of lower than 5% wrong fuel contamination. Remember that it is very unusual - not impossible to encounter. You can get a few vehicles that don't stand any level of contamination in the slightest.
    2. Between 3.75 and 7.5 litres of Diesel in the Audi (5 to 10%) is a 50/50 condition. Our expertise demonstrates that as many drivers get away with this as those people who break down. Any time you are figuring out whether to chance it and just simply fill it up remember that it is very much like gambling it all on black - you have a 50/50 possibility of it being ok.
    3. Anything over 7.5 litres of Diesel in a Petrol R8Quattro ought to straightaway be drained out seeing as your likelihood of succeeding with that amount of contamination is very likely below one in 50 - definitely long odds.
  2. Put Diesel in a Petrol Audi and drove it: Have you observed any kind of performance problems as a result of putting the bad fuel in the R8Quattro? If you have, get it drained irrespective of the volume of Diesel or even the contamination ratio. Continually driving a vehicle that is already starting to suffer from the consequences of fuel contamination will probably only bring about more damage affecting the fuel system parts.
  3. Do you want assurance?
    Simply get it removed. Regardless of the contamination percentage, there is inevitably a certain level of danger in connection with operating a Petrol vehicle on Petrol contaminated with the incorrect fuel. Likely implications of driving on the wrong fuel include things like the engine not starting, running lumpy, decrease in power, wearing of the high-pressure pump, damaged or blocked injectors, and so forth. These are some of the commonest Diesel in Petrol signs and symptoms, and if you notice any of them stop and have 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.
