Wrong Fuel Aston Martin

Put Diesel in a Petrol Aston Martin Lagonda Saloon?

If you've gone and put the wrong fuel in a Aston Martin you probably want to know what you should do about it. The answer to this question depends on the quantity of Diesel you put in your Petrol car.

The first thing we need to look at is fuel tank capacity. So, what is the fuel capacity of a 5.3-litre Petrol Aston Martin Lagonda Saloon? The answer is, the Aston Martin fuel tank capacity is about 113 litres (according to our database).

What to do about putting Diesel in a Petrol Aston Martin will vary dependent on the amount of Diesel used. So, there are three possible scenarios:

(Please Note: These figures are approximates. Running an engine on any amount of incorrect fuel can cause damage, regardless of contamination percentage. Information given here is advice based solely on our customer reports and case histories. Full details should be procured from your vehicle manufacturer.)
  • FIVE PERCENT: If you put less than 5.65 litres of Diesel in a Petrol Aston Martin Lagonda Saloon then in most cases, if the car's tank is completely filled with the correct fuel before it is started, it will probably be fine.
  • FIVE TO TEN PERCENT: If you've put between 5.65 and 11.3 litres then you should probably give us a call. This is the grey area where sometimes you can get away with just topping it up, and sometimes you can't. Call us and, with a bit more information, we'll be able to give you the best advice on what to do next.
  • If you've put more than 11.3 litres of the wrong fuel in your Aston Martin Lagonda Saloon then you should definitely get it drained. This equates to more than 10% contamination and exceeds any "safe" contamination level.
