Audi Fuel Drain


Filling up with Diesel in a Petrol Audi is a regular problem. And its remedy depends on several different things. If you want to know what you must do about this then continue reading.
Right here are the key variables to think about whenever deciding whether or not to get a fuel drain:

  1. What amount of Diesel did you put in to the Audi, considering that the fuel capacity of the Audi Allroad Quattro is usually around 70 litres?
    1. A tiny quantity of Diesel, something like 3.5 litres of Diesel in a Petrol Allroad Quattro will more often than not not necessarily be a huge problem. Experience has shown us that an amount less than 3.5 litres (which is roughly 5% of the overall fuel tank) is oftentimes capable of being completely diluted by entirely topping up the remainder of the tank with Petrol.
      It is rather rare to encounter a motor vehicle suffering from difficulties because of under 5% incorrect fuel contamination. Be aware that it is very uncommon - definitely not impossible to find. You can get some vehicles that won't endure any degree of contamination at all.
    2. Somewhere between 3.5 and 7 litres of Diesel in the Audi (5 to 10%) is really a 50/50 scenario. Our working experience has confirmed that as many people get away with it as those who break down. When you are deciding upon whether or not to chance it and just top it up bear in mind that it is exactly like gambling all of it on black - you've got a 50/50 chance of it working out.
    3. Anything above 7 litres of Diesel in your Petrol Allroad Quattro ought to as soon as possible be drained out seeing that your probability of succeeding with this quantity of contamination is probably lower than one in fifty - seriously huge odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you detected any performance concerns ever since putting the incorrect fuel in the Allroad Quattro? If you have, get it emptied no matter the amount of Diesel or the contamination ratio. Still running a car that is starting to suffer from the effect of fuel contamination can just be responsible for more harm affecting your fuel system.
  3. Are you looking for assurance?
    Then simply just get it removed. No matter the contamination ratio, there is invariably some extent of danger resulting from operating a Petrol motor on Petrol contaminated with the wrong fuel. Likely consequences of driving a vehicle on the wrong fuel include the motor not starting, running lumpy, loss in power, degradation of the high-pressure pump, worn out or bunged injectors, and so on. These are several of the commonest Diesel in Petrol symptoms, and if you recognise any of them then stop driving and have it drained immediately.

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.
