Well the use of the break in oil was just because it's what I had and having never started it before, didn't know what it would have for oil pressure.
With the 20w-50 pressure seemed rather high.
1150 idle, 49psi
2000rpm 70psi
7600rpm 78psi
So to me it seemed that having that much pressure so early but not increasing much with rpm it was just opening/flowing through bypass early.
Now it's-
1150 idle, 37psi
2000rpm 65psi
7600rpm 71psi
Reasoning is, I feel the thinner oil will have a higher flow rate, especially cold/warm up. Also think it would free up a little power and take some load off of the oil pump driveshaft gear.
