Audi Fuel Drain


Filling Diesel in a Petrol Audi is a common problem. And what you have to do about it hinges on several factors. In case you want to find out what you must do about it then read on.
Let us discuss the most crucial variables to be aware of whenever choosing whether to get your car drained:

  1. How much Diesel did you put in to the Audi, taking into account that the fuel tank capacity of your Audi A5 Quattro is most likely about 64 litres?
    1. A tiny quantity of Diesel, less than 3.2 litres of Diesel in a Petrol A5 Quattro will in most situations not be a massive problem. Experience has taught us that quantities less than 3.2 litres (5% of the whole fuel tank volume) is very often capable of being adequately diluted simply by totally filling up the rest of the tank with the correct fuel.
      It's very uncommon to encounter a car going through issues due to below 5% wrong fuel contamination. Bear in mind that it is very infrequently found - in no way impossible to find. You will discover a few vehicles that will not endure any quantity of fuel contamination whatsoever.
    2. In between 3.2 and 6.4 litres of Diesel in the Audi (from 5 to 10%) is a 50/50 situation. Our working experience has revealed that as many people get away with this as those people who break down. Whenever deciding upon whether to chance it and basically fill it up consider that it is the same thing as gambling all of it on black - you have got a 50/50 chance of it being ok.
    3. Anything in excess of 6.4 litres of Diesel in a Petrol A5 Quattro really should promptly be drained out since your likelihood of getting away with this quantity of contamination is certainly less than one in fifty - seriously huge odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you observed any performance problems after putting the incorrect fuel in the A5 Quattro? If that's the case, have it removed regardless of the amount of Diesel or the contamination ratio. Continuing to run running an automobile that is now beginning to suffer from the effect of fuel contamination can just bring about even more harm affecting your fuel system.
  3. Do you want security?
    Then simply just get it removed. Regardless of the contamination ratio, there is always some amount of threat in connection with driving a Petrol engine on fuel contaminated with the incorrect fuel. Likely implications of driving a vehicle on the wrong fuel can include the engine not starting, running unevenly, lack of power, degradation of the high-pressure pump, damaged or clogged injectors, and so on. These are a few of the most common Diesel in Petrol warning signs, and in the event that you observe any of them stop driving and have 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.
