The 5th Gens have roller rockers.
This is the reason for the thinner oils.
The 4th Gens and older have flat tappets, so 15W-40.
Just my two cents

Not roller rockers but hydraulic lifters.
The roller part doesn't matter the 15w oil is supposedly too thick and will clog the oil orifice on the lifter.
Mine has been converted and is running jesel solid roller lifters 15-40 oil for me.
