UOA somewhat skewed due to addition of 0.5qt top off oil at 3880mi. 5w30 is the most popular though I strive for 0w-40.
VOA Viscosity 12.9 TBN 9.4 at OC is 10.1/5.5 I wouldn't think half a qt, +11% of existing fill, of 5w-20 at the 3880mi mark would have made a major impact.
NAPA claims everything is copasetic. The one intriguing result for me was VOA viscosity at 12.9. That is the reading for M1 0w-40 as I understand. Although the base for me frankenblend with the addition of 2qt+ of three other grades of M1 I find it at the very least somewhat unusual to have landed on that same spot.
How low could I safely go on TBN number? I'm not attempting to wring the last drop's worth, but if I could go another grand or two betwixt changes that would be a plus. I generally OC 3-4Kmi, but I stretched it a mite this time.
