Audi Fuel Drain


Filling up with Diesel in a Petrol Audi is a common error. And its remedy is determined by various factors. If perhaps you want to know what you need to do to sort it out then keep on reading.
Right here are the key factors to keep in mind whenever deciding on whether to get it drained:

  1. What amount of Diesel did you put in to the Audi, bearing in mind that the fuel tank capacity of your Audi A7 is probably about 65 litres?
    1. A small amount of Diesel, something like 3.25 litres of Diesel in a Petrol A7 will generally not necessarily be a major problem. Experience has shown us that quantities less than 3.25 litres (about 5% of the overall fuel tank volume) is usually capable of being completely diluted through totally topping up the rest of the tank with the appropriate fuel.
      It is quite rare to find an automobile having issues due to below 5% wrong fuel contamination. Bear in mind that it is uncommon - in no way impossible to encounter. You will discover a number of motor vehicles that won't stand any degree of contamination whatsoever.
    2. Anywhere between 3.25 and 6.5 litres of Diesel in the Audi (from 5 to 10%) is more of a 50/50 condition. Our experience has confirmed that as many drivers get away with this as those who break down. Whenever you are deciding upon whether to risk it and just top it up remember that it is just like gambling all of it on black - you've got a 50/50 possibility of it being ok.
    3. Anything above 6.5 litres of Diesel in a Petrol A7 ought to as soon as possible be drained as your probability of driving with this quantity of contamination is in all likelihood less than one in 50 - extremely big odds.
  2. Put Diesel in a Petrol Audi and drove it: Have you spotted any performance troubles as a result of putting the incorrect fuel in the A7? If so, have it drained irrespective of the amount of Diesel or the contamination ratio. Still running an automobile that is already starting to suffer from the effects of fuel contamination can only bring about progressively more damage affecting the fuel system components.
  3. Would you like assurance?
    Then simply just get it drained. Whatever the contamination ratio, there is invariably some degree of risk in connection with running a Petrol engine on Petrol contaminated with Diesel. Probable implications of driving a vehicle on the incorrect fuel can include the engine refusing to start, running lumpy, loss of power, wearing of the high-pressure pump, damaged or clogged injectors, and the like. These are several of the most common Diesel in Petrol symptoms, and should you detect any of them stop and have it removed 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.
