Aston Martin Fuel Drain


Filling up with Diesel in a Petrol Aston Martin is a regularly occurring error. And what you need to do about it is determined by several different factors. In case you want to know what to do about this then please read on.
Listed here the most important variables to think about whenever making a decision whether or not to have it drained:

  1. What level of Diesel have you put into the Aston Martin, keeping in mind that the fuel tank capacity of your Aston Martin DBS is normally approximately 78 litres?
    1. A small quantity of Diesel, something like 3.9 litres of Diesel in a Petrol DBS will in most situations not really be a significant problem. Experience has demonstrated to us that quantities less than 3.9 litres (which is close to 5% of the entire fuel tank volume) is quite often able to be adequately diluted by means of wholly topping up the rest of the tank with the right fuel.
      It's extremely uncommon to find a vehicle having issues with lower than 5% wrong fuel contamination. Bear in mind that it's uncommon - not impossible to encounter. There are actually a number of automobiles that don't stand any amount of fuel contamination in the slightest.
    2. Between 3.9 and 7.8 litres of Diesel in the Aston Martin (5 to 10%) is a 50/50 scenario. Our practical experience has revealed that as many drivers get away with it as those who break down. When deciding on whether or not to chance it and basically fill it up bear in mind that it is much like betting it all on black - you have got a 50/50 chance of it working out.
    3. Anything over 7.8 litres of Diesel in your Petrol DBS should straight away be drained seeing as your probability of driving with this amount of contamination is almost certainly less than one in fifty - genuinely huge odds.
  2. Put Diesel in a Petrol Aston Martin and drove it: Have you noted any performance issues since putting the bad fuel in the DBS? If that's the case, get it drained regardless of the quantity of Diesel or the contamination ratio. Proceeding to run running a motor vehicle that is currently starting to suffer from the effect of wrong fuel contamination will probably just result in increasing amounts of damage being caused to the fuel system components.
  3. Are you looking for assurance?
    Simply get it emptied. Regardless of contamination percentage, there is inevitably some degree of threat in connection with driving a Petrol vehicle on Petrol contaminated with Diesel. Probable results of driving a vehicle on the wrong fuel normally include the motor not starting, running lumpy, loss in power, wearing of the high-pressure pump, damaged or blocked injectors, and so forth. These are some of the most frequently seen Diesel in Petrol warning signs, and in the event that you observe any of them then stop driving and have it removed right now.

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.
