Audi Fuel Drain

ABOUT

Putting Diesel in a Petrol Audi is a common mistake to make. And what you have to do about it depends on several things. In case you want to know what you need to do about this then please read on.
Listed below are the most important factors to be aware of whenever choosing whether or not to get a fuel drain:

  1. What level of Diesel did you put in to the Audi, keeping in mind that the fuel tank capacity of your Audi A4 is probably approximately 62 litres?
    1. A small quantity of Diesel, less than 3.1 litres of Diesel in a Petrol A4 will generally not be a big problem. Experience has shown us that quantities less than 3.1 litres (which is close to 5% of the overall fuel tank volume) is oftentimes capable of being sufficiently diluted through thoroughly topping the tank with the correct fuel.
      It's quite unusual to encounter a car or truck going through problems with below 5% wrong fuel contamination. Please remember it is very unusual - not impossible to encounter. You will discover a number of cars that will not endure any amount of fuel contamination whatsoever.
    2. Somewhere between 3.1 and 6.2 litres of Diesel in the Audi (from 5 to 10%) is really a 50/50 scenario. Our practical experience has demonstrated that as many people get away with this as those people who break down. Any time you're deciding upon whether to risk it and just fill it up recognise that it is just like gambling your car on black - you've got a 50/50 chance of it working.
    3. Anything in excess of 6.2 litres of Diesel in a Petrol A4 really should promptly be removed seeing that your likelihood of getting away with this level of contamination is certainly lower than one in fifty - genuinely big odds.
  2. Put Diesel in a Petrol Audi and drove it: Have you observed any kind of performance concerns after putting the incorrect fuel in your A4? If so, have it drained irrespective of the volume of Diesel or even the contamination ratio. Continuing to run running a vehicle that is now beginning to suffer from the effect of wrong fuel contamination will probably likely cause even more damage affecting the fuel system components.
  3. Do you need reassurance?
    In that case get it removed. No matter the contamination percentage, there is always a certain level of risk connected with running a Petrol motor on Petrol contaminated with the incorrect fuel. Probable outcomes of driving on the wrong fuel normally include the engine refusing to start, running unevenly, decrease in power, wearing of the high-pressure pump, damaged or clogged injectors, etc. These are a few of the most common Diesel in Petrol symptoms, and if you observe any of them stop driving and get it drained as soon as possible.

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?

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.
