I was thinking about going to a 5w-40 vs 0w-40 in my ram because I live in the land of scorched earth. When I tow it is from on thousand feet above see level to almost 8 thousand feet in less than 2 hours and things get pretty hot. There are no signs of issues but was thinking this may be an extra level of protection in this environment. I wouldn't imagine such a small increase would affect the VVT but would rather get some input before I gave it a shot.

Thanks
