Hello my fellow 928 owners, I am new to my 928, I have owned a 924 turbo in the 80's but this car is so much more! - anyway I have been looking to go synthetic, and would like to use Mobil 1, although not committed to this brand, i have been looking at their web site, and they recommend 0w40 which is straight weight oil, I run straight weight oil in my airplane (piper aztec) anyway i would like some owners input as to what i should be using - Thanks - Tom
