You know, me 5+ years ago....I was worried 5W-20 wasn't sufficient. However, I was wrong. For instance, the Coyote 5.0 on 5W-20 Amsoil Signature Series, 10,000 mile oil change interval, and 30+ 1/8 mile track passes @ 7.5 seconds....
results were amazing! Nothing more was required for a bolt on basic Coyote.
