Robert, I run fully synthetic Mobil 1 20w50 in my car.It previously ran on conventional oils.I was at first reluctant to switch to a modern synthetic thinking it may simply run straight through the engine.However I was persuaded by some people to try the Mobil 1. My fear of the oil leaking out was unfounded and nearly 6 months later the oil still has a dark gold colour to it,not nearly as black and dirty as the regular oil got. The only difference I have noticed is that the car is alot less reluctant to start on a cold morning.I have experienced no increase in performance or drivability. i still think you should change your oil twice a year whether its synthetic or not.The other benefit of the synthetics is they contain many cleaning detergents so they'll keep the motor cleaner. To each his own I say. Andrew VIN 2883 Sydney,Aus. --- therealdmcvegas <DMCVegas@xxxx> wrote: >. Granted though, you don' have to > change it as often.
