I also run synthetic oil in one of my cars, the BMW 745i. Because it is a high horsepower turbo motor, I feel that Mobil 1 is the best choice for it. I run the 10W-30 full synthetic blend and it pumps very quickly after initial startup (a BIG plus over dino oils). In my other cars I just stick with good old Castrol GTX 10W-40. Works well year-round and is a long time trusted brand.
