Audi Fuel Drain

ABOUT

Filling Diesel in a Petrol Audi is a common mistake. And its remedy depends upon a few things. If you want to find out what it is best to do to fix it then read on.
Let us discuss the main factors to think about when choosing whether to get a fuel drain:

  1. How much Diesel did you put in the Audi, taking into consideration that the fuel tank capacity of the Audi S4 is usually roughly 62 litres?
    1. A small amount of Diesel, something like 3.1 litres of Diesel in a Petrol S4 will generally not really be a major problem. Experience has proven to us that anything under 3.1 litres (which is approximately 5% of the entire fuel tank capacity) is in many instances capable of being sufficiently diluted simply by wholly topping the tank with Petrol.
      It's quite unusual to find an automobile experiencing difficulties because of under 5% incorrect fuel contamination. Bear in mind that it is very infrequently found - definitely not impossible to find. There are actually a few motor vehicles that don't endure any level of contamination in the slightest.
    2. Between 3.1 and 6.2 litres of Diesel in the Audi (from 5 to 10%) is really a 50/50 scenario. Our expertise has demonstrated that as many drivers get away with this as all those who don't. Any time you are figuring out whether to risk it and just simply fill it up consider that it is just like gambling your car on black - you will have a 50/50 chance of it working out.
    3. Anything over 6.2 litres of Diesel in a Petrol S4 must straightaway be drained out because your likelihood of getting away with that quantity of contamination is certainly below one in fifty - seriously huge odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you noted any performance problems after putting the bad fuel in your S4? If so, get it drained regardless of the volume of Diesel or even the contamination percentage. Still driving a car that is already beginning to suffer from the effect of wrong fuel contamination can likely lead to progressively more harm being caused to your fuel system components.
  3. Do you want reassurance?
    Then get it drained. Regardless of contamination ratio, there is always a certain level of risk affiliated with operating a Petrol vehicle on Petrol contaminated with the incorrect fuel. Likely implications of driving a car on the wrong fuel normally include the engine refusing to start, running lumpy, loss of power, wearing of the high-pressure pump, worn or bunged injectors, and so forth. These are some of the most frequently seen Diesel in Petrol signs and symptoms, and if you recognise any of them then stop driving and get it drained asap.

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?

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 Petrol car on Diesel 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 Diesel can I get away with in a Petrol 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 Petrol 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.
