Audi Fuel Drain


Filling up with Diesel in a Petrol Audi is a regular error. And its solution is dependent upon a number of factors. In the event that you would like to know what it is best to do to fix it then keep reading.
Right here are the most important factors to be aware of whenever making a decision whether or not to get a fuel drain:

  1. What level of Diesel did you put into the Audi, taking into account that the fuel tank capacity of the Audi A8 Quattro is probably approximately 80 litres?
    1. Hardly any Diesel, less than 4 litres of Diesel in a Petrol A8 Quattro will typically not necessarily be a significant problem. Experience has shown us that quantities under 4 litres (approximately 5% of the total fuel tank capacity) is often capable of being completely diluted by means of totally topping up the rest of the tank with the right fuel.
      It's quite uncommon to come across a motor vehicle going through problems because of below 5% incorrect fuel contamination. Do not forget that it is infrequently found - not impossible to encounter. There are actually a few cars that won't endure any level of contamination whatsoever.
    2. Somewhere between 4 and 8 litres of Diesel in the Audi (from 5 to 10%) is more of a 50/50 condition. Our practical experience has shown that as many people get away with it as those who don't. Any time you are deciding whether or not to chance it and basically fill it up remember that it is very much like wagering all of it on black - you will have a 50/50 possibility of it working out.
    3. Anything over 8 litres of Diesel in your Petrol A8 Quattro must straightaway be drained since your probability of succeeding with that level of contamination is almost certainly less than one in 50 - genuinely huge odds.
  2. Put Diesel in a Petrol Audi and drove it: Have you noted any performance concerns as a result of putting the incorrect fuel in the A8 Quattro? If that's the case, get it emptied irrespective of the amount of Diesel or the contamination ratio. Continuing to run running a vehicle that is already starting to suffer the effect of wrong fuel contamination will probably likely be responsible for progressively more damage affecting your fuel system components.
  3. Are you interested in assurance?
    Then get it removed. Whatever the contamination ratio, there is invariably some degree of threat connected to running a Petrol motor on fuel contaminated with Diesel. Possible final outcomes of driving a vehicle on the incorrect fuel normally include the engine refusing to start, running unevenly, losing power, wearing of the high-pressure pump, worn out or blocked injectors, and so forth. These are some of the commonest Diesel in Petrol signs and symptoms, and if you notice any of them then cease driving and have it drained right now.

Diesel in Petrol FAQs

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.
