"Sticking to the computer" is contingent upon it having the latest firmware TSB, or at least a version from 2014+. My computer oil life indicator spuriously plunged to 3% at 4,200 miles on the 2013 factory firmware version.
However, barring that I suggest just trusting the computer given the several UOA's published on this subforum so far. My oil had a TBN of 4.5
at first change @ 4,200 miles. Subsequent UOAs from other users who have gone farther before changing (7,000 miles
, 7,500 miles
) also show plenty of life remaining.
10,000 miles between changes seems very plausible while remaining within a safety margin. I'm going to change when the computer algorithm suggests and I will have a followup UOA. I fully expect to have a good UOA result for the 10,000 mile oil.
