Audi Fuel Drain


Putting Diesel in a Petrol Audi is a regular problem. And its remedy will depend on several things. In the event that you would like to know what you ought to do to sort it out then read on.
Listed here the most important factors to take into account when making a decision whether to get a fuel drain:

  1. How much Diesel did you put in to the Audi, considering that the fuel tank capacity of your Audi Q5 Quattro is in most cases roughly 75 litres?
    1. A small quantity of Diesel, something like 3.75 litres of Diesel in a Petrol Q5 Quattro will usually not really be a big problem. Experience has proven to us that anything under 3.75 litres (which is roughly 5% of the whole fuel tank capacity) is frequently able to be completely diluted by totally filling up the rest of the tank with the correct fuel.
      It's highly rare to find a car or truck going through issues because of below 5% incorrect fuel contamination. Keep in mind that it's uncommon - definitely not impossible to find. You can get a number of motor vehicles that will not stand any degree of fuel contamination whatsoever.
    2. In between 3.75 and 7.5 litres of Diesel in the Audi (from 5 to 10%) is a 50/50 condition. Our experience has confirmed that as many drivers get away with it as those people who break down. Any time you're deciding whether or not to risk it and just top it up bear in mind that it is just like gambling everything on black - you have a 50/50 possibility of it working.
    3. Anything more than 7.5 litres of Diesel in your Petrol Q5 Quattro ought to as soon as possible be removed as your probability of getting away with this amount of contamination is in all likelihood lower than one in 50 - extremely big odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you detected any performance problems ever since putting the wrong fuel in your Q5 Quattro? If that's the case, have it removed regardless of the quantity of Diesel or the contamination percentage. Proceeding to drive running a vehicle that is now starting to suffer from the consequences of wrong fuel contamination will probably likely lead to progressively more harm affecting your fuel system parts.
  3. Do you need reassurance?
    In that case get it emptied. Whatever the contamination ratio, there is always some extent of risk caused by operating a Petrol engine on fuel contaminated with the incorrect fuel. Possible implications of driving on the wrong fuel include things like the engine not starting, running lumpy, losing power, wearing of the high-pressure pump, damaged or clogged injectors, and the like. These are a few of the commonest Diesel in Petrol symptoms, and if you recognise 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?


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.
