Audi Fuel Drain

ABOUT

Putting Petrol in a Diesel Audi is a well-known problem. And its remedy will depend on a number of things. In the event that you would like to find out what it is advisable to do to sort it out then please read on.
These are the most important factors to to consider whenever determining whether or not to get a fuel drain:

  1. What level of Petrol did you put in to the Audi, taking into consideration that the fuel tank capacity of your Audi A8 TDI Quattro is in most cases around 90 litres?
    1. A tiny amount of Petrol, something like 4.5 litres of Petrol in a Diesel A8 TDI Quattro will most of the time not necessarily be a significant problem. Experience has shown us that quantities less than 4.5 litres (about 5% of the whole fuel tank volume) is in many instances able to be sufficiently diluted by means of thoroughly topping up the tank with the appropriate fuel.
      It's quite unusual to come across a motor vehicle experiencing issues due to lower than 5% wrong fuel contamination. Please remember it is infrequently found - certainly not impossible to find. You will discover some vehicles that won't endure any amount of contamination in the slightest.
    2. In between 4.5 and 9 litres of Petrol in the Audi (from 5 to 10%) is more of a 50/50 situation. Our expertise has shown that as many drivers get away with this as those who don't. Whenever deciding on whether or not to chance it and simply fill it up consider that it is much like betting all of it on black - you've got a 50/50 possibility of it being ok.
    3. Anything over 9 litres of Petrol in your Diesel A8 TDI Quattro ought to immediately be removed since your probability of succeeding with this quantity of contamination is in all likelihood lower than one in fifty - really long odds.
  2. Put Petrol in a Diesel Audi and drove it: Have you observed any performance problems after putting the wrong fuel in the A8 TDI Quattro? In that case, get it drained no matter the amount of Petrol or the contamination ratio. Still running an automobile that is beginning to suffer the effects of fuel contamination will probably only cause even more harm affecting your fuel system.
  3. Are you interested in assurance?
    Then simply just get it removed. Regardless of the contamination ratio, there is invariably a certain level of danger connected to operating a Diesel motor on Diesel contaminated with Petrol. Possible final outcomes of driving on the wrong fuel include things like the motor refusing to start, running unevenly, decrease in power, wearing of the high-pressure pump, worn or clogged injectors, and so on. These are several of the most typical Petrol in Diesel warning signs, and should you detect any of them then cease driving and get it removed right away.

Petrol in Diesel FAQs

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel car and drove it. What do I do?

Answer

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

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 Petrol can I get away with in a Diesel 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?

Answer

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?

Answer

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 Diesel and add some 2-stroke oil?

Answer

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.
