Audi Fuel Drain


Filling Diesel in a Petrol Audi is a common mistake to make. And what you want to do about it depends upon a number of factors. In case you would like to find out what you have to do about it then keep on reading.
Let us discuss the most crucial variables to be aware of when deciding on whether to get it drained:

  1. How much Diesel have you put in to the Audi, keeping in mind that the fuel capacity of your Audi A1 is in most cases roughly 45 litres?
    1. A small amount of Diesel, something like 2.25 litres of Diesel in a Petrol A1 will more often than not not be a huge problem. Experience has demonstrated to us that anything under 2.25 litres (5% of the whole fuel tank capacity) is usually able to be sufficiently diluted through totally topping the rest of the tank with the right fuel.
      It's rather uncommon to find a motor vehicle experiencing problems because of under 5% incorrect fuel contamination. Remember that it is very infrequent - certainly not impossible to encounter. You will discover a number of vehicles that will not endure any amount of contamination whatsoever.
    2. Between 2.25 and 4.5 litres of Diesel in the Audi (from 5 to 10%) is more of a 50/50 situation. Our expertise has revealed that as many people get away with it as those who don't. When deciding upon whether to risk it and just top it up recognise that it is the same as wagering all of it on black - you have got a 50/50 chance of it working out.
    3. Anything over 4.5 litres of Diesel in your Petrol A1 ought to right away be drained seeing as your probability of getting away with that amount of contamination is more than likely less than one in fifty - genuinely big odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you detected any performance issues after putting the incorrect fuel in your A1? If that's the case, have it drained regardless of the quantity of Diesel or even the contamination percentage. Still driving an automobile that is starting to suffer the effect of fuel contamination will definitely end up in even more damage affecting your fuel system parts.
  3. Are you interested in peace of mind?
    You should get it removed. No matter the contamination ratio, there is inevitably some degree of danger in connection with operating a Petrol engine on fuel contaminated with the wrong fuel. Possible implications of driving a car on the wrong fuel can include the motor refusing to start, running lumpy, decrease in power, degradation of the high-pressure pump, worn out or clogged injectors, etc. These are some of the most common Diesel in Petrol signs or symptoms, and should you notice any of them then stop driving and get it drained asap.

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?


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.
