Whats Best Oil To Run,whats Ya Opinion

[vfast]

really? who do you think make the oil for ford????blend is just a waste of cash...amsoil is the only 100% synthetic oil out on the market...would I run it 25K like they advertise? oh hell no...but for 5-7500K yes.....again filtration is key...if you want total protection than add a oil primer to the engine there about a few 100....

Ford engineers put a great deal of time and effort into testing the motor with Motorcraft 5w20 Synthetic Blend. Why not stick with the oil that the motor was designed to be run with?
