The heat difference is small, the protection difference
could be large but it's your money. However, you still don't know what your pressures are and this is something you really should know before committing to any viscosity oil. It's illogical to potentially sacrifice protection in order run oil a few degrees cooler.
If you haven't gone through Element Tunings findings you may want to. These engines are HORRIBLE at making good pressure with hot oil. Dezoris documented the same thing.
