Please make sure if not using dealer or specialist for changing the oil that it is the correct grade (bmw do use 10w 60 fully synthetic in there new m3 etc) and the correct procedure is followed as it is not the same as other cars, and if not done correctly you will NOT get all the old oil out, you have two areas to drain, then the main oil filter to replace and two further metal filters to remove clean and refit. Also resetting the service reminder can only be done with the correct Aston Martin diagnostic equipment. Please Please Please do it properly as trying to save a bit of cash now could become a very expensive repair later.
