Audi Fuel Drain


Putting Diesel in a Petrol Audi is a regularly occurring problem. And exactly what you should do about it is determined by several things. If perhaps you would like to find out what you should do about it then keep reading.
Listed here the key factors to consider whenever choosing whether or not to get the car drained:

  1. What amount of Diesel have you put in the Audi, bearing in mind that the fuel tank capacity of your Audi A6 is usually around 80 litres?
    1. A small amount of Diesel, something like 4 litres of Diesel in a Petrol A6 will normally not really be a huge problem. Experience has shown us that an amount less than 4 litres (which is roughly 5% of the fuel tank volume) is in many instances capable of being completely diluted by thoroughly filling up the rest of the tank with Petrol.
      It's quite uncommon to find a car or truck experiencing problems with under 5% incorrect fuel contamination. Please remember it is unusual - in no way impossible to encounter. There are a few vehicles that won't stand any degree of contamination at all.
    2. Somewhere between 4 and 8 litres of Diesel in the Audi (5 to 10%) is more of a 50/50 scenario. Our experience demonstrates that as many drivers get away with it as those who break down. Any time you're deciding whether to chance it and just fill it up remember that it is the same as wagering your car on black - you've got a 50/50 chance of it working out.
    3. Anything above 8 litres of Diesel in your Petrol A6 should right away be drained since your likelihood of driving with this amount of contamination is certainly lower than one in fifty - extremely big odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you detected any kind of performance difficulties after putting the incorrect fuel in the A6? If you have, get it drained irrespective of the volume of Diesel or the contamination percentage. Proceeding to run driving a vehicle that is already beginning to suffer the effect of fuel contamination will probably likely end up in even more harm being done to your fuel system components.
  3. Would you like peace of mind?
    In that case get it emptied. Whatever the contamination percentage, there is always some extent of threat resulting from running a Petrol engine on Petrol contaminated with the wrong fuel. Possible final outcomes of driving a car on the wrong fuel can include the engine not starting, running unevenly, loss of power, wearing of the high-pressure pump, worn or bunged injectors, etc. These are several of the most typical Diesel in Petrol warning signs, and if you detect any of them cease driving and get it removed right now.

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.
