Audi Fuel Drain


Filling up with Diesel in a Petrol Audi is a fairly typical mistake to make. And its remedy is based on an assortment of factors. In the event that you would like to know what it is best to do about this then please read on.
Here are the most crucial variables to be aware of when deciding on whether or not to get the car drained:

  1. What level of Diesel have you put in the Audi, taking into account that the fuel tank capacity of your Audi RS3 is in most cases around 60 litres?
    1. A tiny amount of Diesel, less than 3 litres of Diesel in a Petrol RS3 will in most cases not be a huge problem. Experience has proven to us that anything less than 3 litres (which is close to 5% of the total fuel tank) is often capable of being sufficiently diluted through wholly topping up the tank with the right fuel.
      It's extremely unusual to encounter a car or truck having difficulties with lower than 5% incorrect fuel contamination. Be aware that it is infrequent - not impossible to encounter. There are a number of cars that don't stand any quantity of contamination whatsoever.
    2. Anywhere between 3 and 6 litres of Diesel in the Audi (from 5 to 10%) is more of a 50/50 condition. Our experience has shown us that as many people get away with it as all those who break down. Whenever figuring out whether to risk it and basically fill it up bear in mind that it is the same as betting your car on black - you will have a 50/50 possibility of it working.
    3. Anything more than 6 litres of Diesel in your Petrol RS3 should as soon as possible be drained out because your likelihood of succeeding with this amount of contamination is probably below one in 50 - extremely big odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you noticed any kind of performance concerns after putting the incorrect fuel in your RS3? In that case, get it emptied irrespective of the quantity of Diesel or the contamination percentage. Continually driving a motor vehicle that is currently starting to suffer the effects of fuel contamination will probably only cause even more damage being caused to your fuel system.
  3. Do you need assurance?
    Then simply just get it emptied. No matter the contamination ratio, there is invariably some amount of danger connected to running a Petrol engine on fuel contaminated with the incorrect fuel. Possible consequences of driving a car on the wrong fuel normally include the engine not starting, running unevenly, lack of power, degradation of the high-pressure pump, worn or clogged injectors, and the like. These are some of the commonest Diesel in Petrol warning signs, and if you notice any of them stop and have it drained as soon as possible.

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.
