What are the potential advantages that you've found in semi-synthetic over group III full-syn?I used Motorcraft 5W-20 semi-synthetic motor oil in my wife's Lamborghini Murcielago. I have used the same oil in other sports cars that specify 5W-40 grade oils. I personally like this oil and feel that semi-synthetic oils may have advantages, in many cases, over some fully "synthetic" oils.
