I run 10-30 year around, for the most part. Even in Idaho.

Oklahoma and 10w30 year round - Mobile 1.
It just doesn't get cold enough here to justify 5w30.

But the question is would that solve piston slap, right?? Any thoughts???

Only run Mobil1 5W-30... I have no reason to switch to 10W, 5W is all weather year round oil... I always run what the engine specs to in all my cars.

:bang

I don't think it would have any major effect.

I put 10W-30 in, at the first oil change.

Mobil 1 10-30 but I think I will go to 20-50 to increase oil pressure.

Stay with the 10-30. The engine is designed for 10-30 or lower. The bearing clearances are set for 30 max unless you have very high mileage and have had a mech recommend a higher viscosity.
Just my .02

Looks like an advise from a pro that I want to listen to. Does 100,000 miles is high mileage?
