Audi Fuel Drain


Putting Diesel in a Petrol Audi is a fairly typical mistake to make. And exactly what you have to do about it depends upon a few things. If you would like to know what you have to do about this then please read on.
These are the most important factors to to consider whenever deciding whether or not to get a fuel drain:

  1. Exactly how much Diesel did you put in the Audi, taking into account that the fuel tank capacity of the Audi RS5 Quattro is usually around 64 litres?
    1. Hardly any Diesel, something like 3.2 litres of Diesel in a Petrol RS5 Quattro will more often than not not necessarily be a massive problem. Experience has demonstrated to us that quantities less than 3.2 litres (which is roughly 5% of the entire fuel tank volume) is quite often able to be adequately diluted through entirely filling up the remainder of the tank with the right fuel.
      It's pretty uncommon to encounter a vehicle experiencing issues with lower than 5% incorrect fuel contamination. Do not forget that it's rare - not impossible to find. You can get certain cars that will not endure any degree of fuel contamination whatsoever.
    2. Somewhere between 3.2 and 6.4 litres of Diesel in the Audi (5 to 10%) is really a 50/50 condition. Our expertise has shown us that as many motorists get away with this as all those who break down. When figuring out whether or not to chance it and just top it up consider that it is much like betting everything on black - you have a 50/50 possibility of it working out.
    3. Anything over 6.4 litres of Diesel in a Petrol RS5 Quattro really should immediately be drained seeing as your probability of driving with this quantity of contamination is in all likelihood lower than one in 50 - seriously long odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you detected any performance concerns since putting the incorrect fuel in the RS5 Quattro? If so, have it removed no matter the amount of Diesel or the contamination percentage. Still running a motor vehicle that is already starting to suffer the effect of fuel contamination can only lead to more and more harm being done to your fuel system.
  3. Do you need reassurance?
    Simply get it emptied. Whatever the contamination ratio, there is always a certain level of danger connected to driving a Petrol motor on Petrol contaminated with the incorrect fuel. Possible consequences of driving a vehicle on the wrong fuel include things like the motor not starting, running unevenly, loss in power, degradation of the high-pressure pump, damaged or blocked injectors, and the like. These are several of the most common Diesel in Petrol warning signs, and in the event that you notice any of them then 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.
