I run Mobil 1 20w50 and I'm wondering if I should move up to a heavy weight, like Amsoil 50 or 60 weight racing oil. I'm in South Carolina, regularly 95+ in the summer. A buddy of mine running dino oil uses HD 60w in the summer. Just curious if that's standard or if my M1 or Amsoil 20w50 is sufficient in extreme heat.

I'm sure this has come up before, but not letting me search on 3 letter words makes it hard to find if it has!

I'm on a 2005 Wide Glide, high compression 95" kit, SE cams, race ignition, SE heads....

Thanks for any input.
