Aston Martin Fuel Drain


Filling up with Diesel in a Petrol Aston Martin is a usual problem. And its solution varies according to several different things. In the event that you want to find out what it is advisable to do about it then keep on reading.
Let us discuss the most crucial factors to to consider when making a decision whether to get a fuel drain:

  1. Exactly how much Diesel did you put in the Aston Martin, keeping in mind that the fuel capacity of your Aston Martin DB9 is most likely roughly 85 litres?
    1. A small quantity of Diesel, something like 4.25 litres of Diesel in a Petrol DB9 will in most cases not necessarily be a big problem. Experience has proven to us that quantities under 4.25 litres (which is almost 5% of the whole fuel tank) is usually able to be sufficiently diluted through entirely filling the tank with Petrol.
      It is pretty unusual to encounter a car or truck having difficulties with less than 5% incorrect fuel contamination. Please remember it's infrequently found - not impossible to find. You will discover a few vehicles that don't endure any level of contamination whatsoever.
    2. Between 4.25 and 8.5 litres of Diesel in the Aston Martin (from 5 to 10%) is really a 50/50 scenario. Our practical experience has shown that as many drivers get away with it as those who break down. Whenever you are deciding upon whether or not to chance it and just top it up remember that it is exactly like wagering everything on black - you've got a 50/50 chance of it working out.
    3. Anything over 8.5 litres of Diesel in a Petrol DB9 really should promptly be drained out since your likelihood of succeeding with this quantity of contamination is almost certainly lower than one in 50 - genuinely long odds.
  2. Put some Diesel in a Petrol Aston Martin and drove it: Have you spotted any performance problems ever since putting the wrong fuel in the DB9? If you have, get it removed irrespective of the volume of Diesel or even the contamination ratio. Continuing to run driving a car that is already starting to suffer the effects of fuel contamination will definitely bring about increasing amounts of harm affecting your fuel system parts.
  3. Do you need assurance?
    Then get it emptied. Regardless of contamination percentage, there is invariably some degree of danger connected with operating a Petrol vehicle on fuel contaminated with Diesel. Possible implications of driving on the incorrect fuel can include the engine not starting, running lumpy, decrease in power, degradation of the high-pressure pump, worn or clogged injectors, and so forth. These are some of the most common Diesel in Petrol symptoms, and if you detect any of them then stop and get it removed right away.

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.
