Hi all, This is my first shared UOA here. I'm on a 5 mile commute now, and had bought a 3-pack of Castrol Act-Evo 10w-40 in gallon jugs. The shifting got kinda rough toward the end of the run, and I found neutral instead of 2nd gear more times than I would like. Kawasaki 10w-40 went back in, with a Fram Ultra filter.

I logged the viscosity in as a 10W/40, but it read more in the 5W/20 range, similar to last time.
Some fuel was found, but that's not enough to thin the viscosity out. Wear changed a bit since last year's
sample, but everything is still within the average range. The TBN was strong at 5.1. I've found my shifting to
get rough towards the end of an oil change too. A fresh fill of oil always smoothes things out for my Honda.
That might be a good gauge as to when to change the oil, or you could try 9,000 miles next. A trace of
insolubles shows excellent oil filtration. ~Luke
