Audi Fuel Drain

ABOUT

Putting Petrol in a Diesel Audi is a very common mistake. And exactly what you need to do about it hinges on a few things. Assuming you want to find out what you ought to do about it then stay with me.
Let us discuss the most important factors to consider whenever choosing whether to have it drained:

  1. What level of Petrol have you put in to the Audi, keeping in mind that the fuel tank capacity of the Audi A6 TDI is in most cases about 80 litres?
    1. A small quantity of Petrol, less than 4 litres of Petrol in a Diesel A6 TDI will quite often not really be a significant problem. Experience has taught us that quantities less than 4 litres (which is 5% of the overall fuel tank) is oftentimes able to be completely diluted through entirely filling the rest of the tank with Diesel.
      It is rather uncommon to come across a car or truck going through problems due to less than 5% wrong fuel contamination. Keep in mind that it is very infrequent - in no way impossible to find. You will discover a few vehicles that won't endure any level of fuel contamination at all.
    2. In between 4 and 8 litres of Petrol in the Audi (from 5 to 10%) is a 50/50 situation. Our practical experience has confirmed that as many people get away with this as those who don't. When you are trying to decide whether or not to risk it and basically fill it up recognise that it is the same as gambling everything on black - you've got a 50/50 possibility of it working out.
    3. Anything in excess of 8 litres of Petrol in your Diesel A6 TDI ought to immediately be drained out as your probability of driving with this amount of contamination is more than likely lower than one in fifty - extremely big odds.
  2. Put Petrol in a Diesel Audi and drove it: Have you noticed any kind of performance problems ever since putting the bad fuel in your A6 TDI? If so, get it removed no matter the volume of Petrol or even the contamination ratio. Still driving an automobile that is starting to suffer the effect of fuel contamination can just end up in increasing amounts of harm being done to the fuel system.
  3. Would you like peace of mind?
    You should get it removed. Regardless of the contamination ratio, there is inevitably some degree of danger affiliated with driving a Diesel engine on Diesel contaminated with the wrong fuel. Possible implications of driving on the incorrect fuel can include the engine refusing to start, running unevenly, loss of power, degradation of the high-pressure pump, worn or bunged injectors, etc. These are some of the commonest Petrol in Diesel signs or symptoms, and should you notice any of them stop driving and have it drained right away.
