Third UOA on this 1000cc water-cooled Suzuki V-Twin. Dummy me forgot when I changed the oil, and it actually could have been left in there for a lot longer. :dunce: RON: Your engine appears to be going through its final stage of break-in. All of the wear metals in this 10W/40-grade oil read basically the same as the previous sample. They also read right around the universal averages for the DL 1000 Suzuki engine. Once your motorcycle hits 10,000 miles the engine should have matured and wear should read average after 2,300 miles of oil use. The TBN was super strong at 11.3 (see note below) showing loads of active additive. No contaminants were found in this sample. Congratulations on your first perfect oil report! UOA#3 Ref. Black.
