Audi Fuel Drain


Filling up with Diesel in a Petrol Audi is a regular mistake to make. And what you want to do about it will depend on several different factors. In the event that you would like to find out what you must do about it then stay with me.
Listed here are the most crucial variables to think about whenever deciding on whether or not to get it drained:

  1. What level of Diesel have you put in to the Audi, taking into consideration that the fuel tank capacity of your Audi R8 Spyder Quattro is usually approximately 80 litres?
    1. Hardly any Diesel, as little as 4 litres of Diesel in a Petrol R8 Spyder Quattro will normally not be a big problem. Experience has proven to us that anything under 4 litres (which is approximately 5% of the overall fuel tank) is generally capable of being sufficiently diluted through totally filling the remainder of the tank with the right fuel.
      It's rather unusual to come across a car or truck suffering from difficulties due to less than 5% incorrect fuel contamination. Be aware that it is very infrequent - certainly not impossible to encounter. You can get a few vehicles that won't endure any quantity of fuel contamination whatsoever.
    2. Anywhere between 4 and 8 litres of Diesel in the Audi (from 5 to 10%) is a 50/50 situation. Our experience has shown that as many drivers get away with it as those who break down. When you are deciding on whether to risk it and just simply fill it up bear in mind that it is the same as gambling all of it on black - you've got a 50/50 chance of it working.
    3. Anything in excess of 8 litres of Diesel in a Petrol R8 Spyder Quattro should really as soon as possible be removed seeing that your likelihood of getting away with this level of contamination is certainly below one in 50 - really long odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you noted any kind of performance issues since putting the incorrect fuel in the R8 Spyder Quattro? If you have, have it emptied irrespective of the amount of Diesel or the contamination percentage. Proceeding to run running a vehicle that is now starting to suffer from the consequences of wrong fuel contamination can only lead to even more damage being caused to your fuel system.
  3. Are you interested in peace of mind?
    Then simply just get it emptied. Regardless of the contamination ratio, there is inevitably some extent of danger resulting from driving a Petrol motor on Petrol contaminated with the wrong fuel. Likely final outcomes of driving a vehicle on the wrong fuel include the motor refusing to start, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or bunged injectors, and the like. These are a few of the commonest Diesel in Petrol warning signs, and should you detect any of them then cease driving and get it removed right away.

Diesel in Petrol Questions

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.
