I was wondering who uses the "moly" content of an oil as one of their prime factors in determining the brand of oil that they use. Oils such as castrol and pennzoil do contain moly, but other popular oils here, such as cheron supreme do not. Is the lack of moly going to make that big of difference in a car that has it's oil changed every 3000 miles?
