The Havoline does everything nicer. I swear. Throttle response and smoothness...everything. On paper the M1 0w30 SL should be a fantastic oil in my Honda 2.4, but I like the 20 weight dino better. Go figure.
btw- the M1 was pretty fresh still, came out at 3000 miles. The Havoline went in as a last minute decision, I was going to refill with M1.
