Here are my 3 lab results of the 2023 R1250RS . The break in , and 1st are BMW 5w / 40 , and the 3rd is Shell T6 5w/40 The T6 was run the extra few miles by miss calculation on my part .
Also The T6 was run a little harder than the 2nd oil change. The T6 has a better viscosity rating at 27xx miles than the BMW Shell made oil . Slightly more ZINC ( ZDP ) in the T6 vs BMW
However the TBN ( life expected left in oil ) is slightly higher in the BMW oil vs the T6 . Both oils have a safe TBN to 5000 miles .
Today discussing this with a oil and gas friend he came up with the though BMW uses natural gas made oil for a lower carbon footprint . Food for thought .
