Hi Rich, As far as I know the only difference between Mobil 1 0w30 and 10w30 is the viscosity or thickness of the oil.O weight will be thinner and flow more easily when the engine is cold than 10w oil. At the Benz dealer I work at we use 0 weight Mobil 1 but for my DeLorean I use the 10 weight oil since it never gets that cold here to warrant it.
