Audi Fuel Drain


Filling Diesel in a Petrol Audi is a well-known mistake. And what you want to do about it is dependent upon a number of things. In the event that you want to find out what you should do to fix it then stay with me.
Listed below are the most important variables to be aware of when determining whether to get it drained:

  1. Exactly how much Diesel did you put in the Audi, keeping in mind that the fuel tank capacity of the Audi SQ5 is in most cases approximately 75 litres?
    1. A small amount of Diesel, less than 3.75 litres of Diesel in a Petrol SQ5 will in most situations not really be a huge problem. Experience has taught us that an amount less than 3.75 litres (roughly 5% of the overall fuel tank volume) is usually capable of being adequately diluted by means of entirely filling up the remainder of the tank with the right fuel.
      It is pretty uncommon to come across a car or truck experiencing problems due to under 5% wrong fuel contamination. Keep in mind it is very infrequent - in no way impossible to find. You will discover a few cars that will not stand any level of fuel contamination at all.
    2. In between 3.75 and 7.5 litres of Diesel in the Audi (from 5 to 10%) is a 50/50 scenario. Our expertise has revealed that as many people get away with it as those who don't. When you are deciding on whether to chance it and basically top it up consider that it is much like betting your car on black - you have got a 50/50 chance of it being ok.
    3. Anything in excess of 7.5 litres of Diesel in your Petrol SQ5 must as soon as possible be removed because your probability of succeeding with that level of contamination is almost certainly lower than one in fifty - extremely big odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you noticed any performance concerns since putting the bad fuel in the SQ5? If so, get it removed irrespective of the volume of Diesel or even the contamination percentage. Still driving an automobile that is already starting to suffer the effects of wrong fuel contamination will definitely cause increasing amounts of damage being done to the fuel system.
  3. Are you interested in peace of mind?
    In that case get it removed. Whatever the contamination ratio, there is invariably some degree of threat in connection with operating a Petrol engine on Petrol contaminated with Diesel. Possible outcomes of driving on the wrong fuel can include the engine not starting, running unevenly, reduced power, wearing of the high-pressure pump, worn or bunged injectors, and so forth. These are a few of the most typical Diesel in Petrol signs and symptoms, and should you observe any of them stop and have it drained immediately.

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.
