I have had my oil sampled in my 350sdl for over a year now, everything is in very
good shape (1991 101K at present)
except for potassium levels that are
elevated. Last 3 changes: 43, 30, 30 ppm
Glycol is negative. Can anyone out there
comment on this high potassium level??
The oil is a mix of 50-50 Mobil one and
miles between change about 3100.
soot very low at .2, TBN at 8.5
