I've got Mobil 1 15w-50 in my 427 side-oiler. After reading the "
Oil Novel" above it seems I should be running something like 0w-30 or 0w-20.
So, would it be worth it to go ahead and change out to the lighter weight
oil? I'm also thinking of using
Amsoil vs Mobil 1.
Car is mainly street, but have been on the track and have NASA HPDE 2 in a few weeks.
I'm trying to "learn to fish" by studying, but in the meantime wouldn't mind if someone would just throw a "fish" on the plate
