So this is my first UOA.
MAKE/MODEL: Honda Motorcycle 700cc OIL TYPE & GRADE: Shell 10W/30 FUEL TYPE: Gasoline (Unleaded) OIL USE INTERVAL: 2,550 Miles MI/HR on Oil 2,550 MI/HR on Unit 15,400 COMMENTS LUCIANO: Yes, this oil change interval worked very well. Universal averages show typical wear for this engine type after about 4,700 miles on the oil. On your 2,550-mile interval, all metals are within the average range. Maybe iron is a touch elevated on a ppm/mile basis, but that could be related to how you use the bike. We'll know a little more about that as trends build. For now, the important thing to know is that there's nothing reading high enough to suspect any serious issues. The viscosity was a little light, but that's probably normal shearing. Nice!
