Audi Fuel Drain


Putting Diesel in a Petrol Audi is a regularly occurring mistake. And its remedy is based on several things. In case you want to know what it is best to do about this then keep on reading.
Let us discuss the key factors to take into account whenever determining whether to have a fuel drain:

  1. How much Diesel did you put in to the Audi, taking into account that the fuel tank capacity of the Audi A8 Hybrid is in most cases about 90 litres?
    1. A tiny amount of Diesel, something like 4.5 litres of Diesel in a Petrol A8 Hybrid will most of the time not be a significant problem. Experience has shown us that anything under 4.5 litres (5% of the entire fuel tank volume) is quite often capable of being adequately diluted simply by wholly filling up the rest of the tank with the right fuel.
      It's extremely rare to find an automobile suffering from issues with under 5% wrong fuel contamination. Do not forget that it is very uncommon - in no way impossible to encounter. There are actually a few cars that will not stand any quantity of fuel contamination at all.
    2. Between 4.5 and 9 litres of Diesel in the Audi (from 5 to 10%) is a 50/50 scenario. Our experience demonstrates that as many motorists get away with this as those who break down. Whenever figuring out whether or not to chance it and just simply fill it up recognise that it is exactly like gambling it all on black - you have a 50/50 possibility of it working.
    3. Anything above 9 litres of Diesel in your Petrol A8 Hybrid must as soon as possible be removed since your likelihood of succeeding with that quantity of contamination is probably lower than one in 50 - genuinely huge odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you observed any kind of performance concerns after putting the incorrect fuel in the A8 Hybrid? If that's the case, get it emptied regardless of the quantity of Diesel or the contamination percentage. Continuing to run driving a car that is already beginning to suffer the effects of wrong fuel contamination can likely end up in even more damage being done to your fuel system.
  3. Do you want security?
    Simply get it removed. No matter the contamination ratio, there is inevitably some degree of threat in connection with driving a Petrol vehicle on Petrol contaminated with Diesel. Likely final outcomes of driving on the wrong fuel include the motor refusing to start, running unevenly, reduced power, degradation of the high-pressure pump, worn or blocked injectors, and so forth. These are several of the commonest Diesel in Petrol warning signs, and should you notice any of them stop driving and have it drained asap.

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.
