1999 Honda ST1100
Water-cooled V4
Shared engine/trans. oil, wet clutch
Comments:
Napa 15W50 Synthetic oil
SuperTech automotive oil filter
MMO as a UCL.
This is my first run with Napa
The wear metals look good and the TBN held up well for 8,000 miles.
The oil did shear down a bit but that doesn't worry me.
I filled the bike with Rotella 5W40 this time.
