Ok, lots of info being thrown around which I appreciate.
Forgot to mention I'm running a WIX filter and for oil I'm running 15/40 Rotello with a zinc additive
(1) thats what we do best! (2) smart move there (no opinion/expertise on the weight choice)
On the oil, given that the climate in the NW I found th 15/40 worked fine. Since I now live in the SW I need to consider changing from the 15/40, maybe a straight 30 wt?
