Ive been running a valvoline vr1 20w50 . Seems the viscosity is a little high . What are you running for viscosity in your 360?

I'm old skool. Run 30wt straight here in Texas it's toasty most of the year! Been running VR-1 before. Now will try Shaeffers 30 race oil and may give Brad Penn a try in the future.
