Audi Fuel Drain


Filling up with Diesel in a Petrol Audi is a very common mistake to make. And what you need to do about it depends on various factors. In the event that you want to find out what you need to do to fix it then read on.
Listed below are the most important variables to think about whenever deciding whether or not to have the car drained:

  1. Exactly how much Diesel did you put into the Audi, considering that the fuel tank capacity of the Audi A5 is most likely about 65 litres?
    1. Hardly any Diesel, less than 3.25 litres of Diesel in a Petrol A5 will usually not really be a major problem. Experience has taught us that anything under 3.25 litres (almost 5% of the whole fuel tank) is frequently able to be completely diluted simply by totally topping the tank with Petrol.
      It's rather rare to encounter a car or truck experiencing difficulties because of under 5% incorrect fuel contamination. Please remember it is very infrequent - in no way impossible to encounter. There are actually certain automobiles that won't stand any level of contamination at all.
    2. Anywhere between 3.25 and 6.5 litres of Diesel in the Audi (from 5 to 10%) is really a 50/50 condition. Our experience has shown that as many motorists get away with it as those who break down. Whenever you are deciding on whether to chance it and just top it up bear in mind that it is the same as betting your car on black - you've got a 50/50 chance of it working.
    3. Anything in excess of 6.5 litres of Diesel in your Petrol A5 should immediately be removed as your likelihood of succeeding with that quantity of contamination is in all likelihood below one in fifty - truly huge odds.
  2. Put Diesel in a Petrol Audi and drove it: Have you seen any kind of performance problems as a result of putting the wrong fuel in the A5? In that case, have it emptied no matter the quantity of Diesel or even the contamination ratio. Still driving an automobile that is now beginning to suffer the effects of fuel contamination will probably typically result in even more harm being caused to your fuel system components.
  3. Do you need reassurance?
    You should get it emptied. Whatever the contamination ratio, there is invariably some extent of threat affiliated with running a Petrol engine on Petrol contaminated with the incorrect fuel. Probable results of driving on the incorrect fuel include things like the engine not starting, running lumpy, loss in power, degradation of the high-pressure pump, damaged or bunged injectors, and so forth. These are a few of the most typical Diesel in Petrol warning signs, and in the event that you observe any of them stop driving and have it drained right now.

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.
