The new UOA is out.
This UOA is from 6600 miles running Shell Rotella 15w40 mineral oil. This sample was taken 600 miles past the specified change interval due to my budget and schedule.
It's unclear whether the high levels of aluminum are being caused by the oil it's self, or some other issue, although I will say that I ran the bike fairly hard on this stuff (wheelies, drag launches, high speed, significant time at WOT.)
Regardless of what's causing the wear, I will never run this stuff in my bike again.
The oil it's self seems to be in okay condition after 6000 miles, which surprises me. TBA is acceptable, and while 11.6 is a mid 30 weight viscosity grade, the oil hasn't thinned out nearly as much as I've expected. I suspect it's because this oil is targeted at diesel engines; I would not be surprised to find it doesn't have as many VIIs as some other 10w40 conventional oils.
From the report:
Quote:
SUGGEST INSPECTING this unit for excessive cylinder region wear; Cylinder region metals (pistons, rings, liners etc.) are at a SEVERE LEVEL; Abrasives (silicon/dirt) are at a MODERATE LEVEL; Copper is at a MINOR LEVEL; Bushing/thrust metal and/or most of the copper may be coming from lube cooler (as applicable); Tin is at a MINOR LEVEL; FUEL DILUTION is at a MINOR LEVEL; FUEL DILUTION has caused viscosity to decrease moderately; Flagged data has been rechecked and confirmed; RESAMPLE IMMEDIATELY so we may verify results;
