5w-30 is the heaviest oil I use and been using Mobil 1 synthetic for 30 years and nearly 20 in my race engines!!

I've been considering going to a lighter weight oil to pick up a few hp one of these days, been having pretty good luck with the VR1 20-50w so I've been hesitant to switch. One of those if it ain't broke don't fix it things for me I guess.
