Audi Fuel Drain


Putting Diesel in a Petrol Audi is a usual mistake to make. And its solution is dependent upon various things. If you want to find out what it is best to do to fix it then keep on reading.
These are the most crucial variables to to consider whenever figuring out whether to get a fuel drain:

  1. What amount of Diesel have you put in the Audi, bearing in mind that the fuel capacity of the Audi RS4 is most likely about 66 litres?
    1. A tiny amount of Diesel, something like 3.3 litres of Diesel in a Petrol RS4 will most of the time not really be a huge problem. Experience has shown us that quantities under 3.3 litres (which is almost 5% of the fuel tank volume) is oftentimes capable of being adequately diluted through entirely topping the remainder of the tank with the right fuel.
      It's very unusual to find a car or truck having difficulties with below 5% incorrect fuel contamination. Keep in mind it is unusual - in no way impossible to encounter. There are some vehicles that don't stand any degree of fuel contamination at all.
    2. Between 3.3 and 6.6 litres of Diesel in the Audi (5 to 10%) is a 50/50 situation. Our expertise has revealed that as many drivers get away with it as those who don't. Any time you are trying to decide whether to risk it and just simply fill it up remember that it is very much like gambling all of it on black - you have a 50/50 possibility of it working.
    3. Anything more than 6.6 litres of Diesel in your Petrol RS4 should immediately be removed seeing as your likelihood of getting away with that quantity of contamination is in all likelihood less than one in 50 - truly long odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you detected any performance concerns after putting the incorrect fuel in your RS4? If so, get it drained irrespective of the amount of Diesel or the contamination ratio. Continuing to run driving a motor vehicle that is now starting to suffer from the consequences of wrong fuel contamination can just bring about more and more damage affecting your fuel system parts.
  3. Are you interested in security?
    In that case get it emptied. Regardless of contamination percentage, there is invariably a certain level of risk connected to running a Petrol vehicle on fuel contaminated with the incorrect fuel. Possible consequences of driving a vehicle on the wrong fuel can include the engine not starting, running lumpy, lack of power, degradation of the high-pressure pump, worn out or clogged injectors, and so on. These are some of the commonest Diesel in Petrol symptoms, and should you detect any of them stop driving and get it removed immediately.

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.
