Amsoil FTW, unleashedbeast has put some great things together on that thread. I'm going Amsoil 10-40 here in a couple weeks.
Does Amsoil not make oil in the recommended viscosity, or is there some thread somewhere with the rationale behind the 10-40?

Thanks, that made it worse!
I have 600miles on the car and I want to change the oil...is it standard procedure on the first oil change to go factory fill then then next change go whatever route?

With all the changes in the 5.8 there is no way I'd run a different viscosity without a real good reason.
Ill let the "pioneers" try different viscosities and see what happens.
It is amazing to me that guys don't trust the guys who designed it to know what viscosity is best.
Why don't you guys wait till you get 7500 miles on it before changing oil? The book calls for 7500. Both my 2010 and 2012 went to the 7500 and them 15000 and so on. Didn't hurt a thing and if it did it was cover by the warranty and only used Motorcraft.
If you beat the piss out of the car it needs to be changed more frequently. If you're the type of guy that just cruises with the car and does an occasional highway pull etc, than that's a different story. It's not like you will hurt the car buy changing oil more frequently. Guys will spend $60k and then wan't to cheap out on oil changes :nonono: Not saying that's you.Why don't you guys wait till you get 7500 miles on it before changing oil? The book calls for 7500.

The motorcraft junk shears down from 50 to 40 fast. So if it's okay to run 40 after 1000 miles it's okay to use it to begin with. Amsoil is 5 times the quality oil that motorcrap is.
