Oil weight?

How many pages back did this dead thread come from???

I wouldn't run 0W-40 just because it's not called out for in the manual, where 10W-40 and 20W-50 are.

With you being in Arizona I would stick with the heavier oils. At LEAST 10W-40.

JMO.

I have 5 quarts of Amsoil 0W40 sitting here waiting for installation in the XX in the next week.

Last oil change I used Castrol Syntec 5W50, and was less than impressed with my shifts after switching from the Castrol 10W40 motorcycle oil.

The more I've learned about oils (and engines) in the last year or so leads me to believe we've all been using way too thick of an oil, which is doing nothing more than robbing us of horsepower.

Not to mention how slowly it circulates on cold starts :wink:
