I only use synthethic oil. Small engines to big engines. Currently using Castrol Edge, and AMSoil and Royal Purple. Use it in crankcase, transmissions, grease fittings, hydraulic tanks,trasfer case, differentials - anything and everything. It lasts longer and significantly reduces friction. For example if you put Royal Purple synthetic oil in a small block Chevy you will pick up 8 to 12 hp and ft lbs torque. That is a lot without changin a thing. No simple bolt on could add that kind of power for that price. Think about that huge reduction in friction - 8-12 hp/ft lbs - wow! AMS transmission fluid lowers temp in trans and that means longer life. So I will run the synthetic engine oil for 10k miles about 3 times as long as convential oil so the cost is about the same and I get a 2% plus increase in gas milage (which puts me in the black without even considering much improved friction protection and longer engine life and important to me, a lot less time changing oil). To me it is a no brainer. Pays for itself and then some. Facts are facts.
