Finally tested out the 10w-40
oil today.
65-70 psi cold at any RPM.
57 psi once warmed up and anything above about 2,000 rpms
40 psi at 1,200 rpm (where it likes to idle if I don't drag it down a bit).
30 psi at 1,000 rpm (when I drag it down a bit)
Oil temps ran a bit higher then in the past with the 20w-50 but my guess is outside temps had something to do with it.
