Audi Fuel Drain

ABOUT

Putting Petrol in a Diesel Audi is a well-known mistake. And what you should do about it depends upon several different factors. If you would like to know what you must do about it then stay with me.
Here are the most crucial variables to take into consideration when making a decision whether or not to have a fuel drain:

  1. How much Petrol did you put in the Audi, bearing in mind that the fuel tank capacity of the Audi Q3 TDI is most likely approximately 64 litres?
    1. A small amount of Petrol, something like 3.2 litres of Petrol in a Diesel Q3 TDI will more often than not not necessarily be a massive problem. Experience has shown us that quantities under 3.2 litres (which is 5% of the overall fuel tank capacity) is in many instances able to be completely diluted simply by thoroughly filling the tank with the right fuel.
      It is highly uncommon to find a car going through issues because of below 5% incorrect fuel contamination. Keep in mind that it is very rare - definitely not impossible to find. You can get a number of automobiles that won't endure any amount of fuel contamination in the slightest.
    2. Somewhere between 3.2 and 6.4 litres of Petrol in the Audi (from 5 to 10%) is more of a 50/50 situation. Our practical experience has demonstrated that as many drivers get away with this as all those who break down. When figuring out whether or not to chance it and basically top it up consider that it is just like betting it all on black - you have got a 50/50 chance of it being ok.
    3. Anything over 6.4 litres of Petrol in your Diesel Q3 TDI must straightaway be drained out seeing as your likelihood of driving with that quantity of contamination is in all likelihood less than one in fifty - seriously huge odds.
  2. Put Petrol in a Diesel Audi and drove it: Have you noticed any performance problems since putting the bad fuel in the Q3 TDI? If so, get it emptied no matter the amount of Petrol or even the contamination ratio. Proceeding to run driving an automobile that is currently beginning to suffer the consequences of fuel contamination will probably definitely lead to even more harm affecting your fuel system components.
  3. Are you looking for assurance?
    In that case get it emptied. Regardless of the contamination ratio, there is inevitably some amount of danger caused by driving a Diesel motor on Diesel contaminated with Petrol. Likely implications of driving a car on the wrong fuel can include the motor refusing to start, running unevenly, reduced power, degradation of the high-pressure pump, damaged or clogged injectors, and so on. These are a few of the most typical Petrol in Diesel symptoms, and in the event that you observe any of them then stop and get it drained as soon as possible.

Petrol in Diesel Questions

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

Will driving a Diesel car on Petrol cause damage to it?

Answer

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?

Answer

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.
