Car is driven mostly highway, with the usual metro DC traffic at times. Then the engine gets to take a nap. Most of the time it's howling along at 70 mph.
I couldn't wait to do this UOA. The owned-since-new family Prius started burning oil somewhere in the 100k mile range. Got to be about 2 make up quarts within a 7500 oil change interval, on a car with a ~3.5 quart sump. Had run 5w30 synthetic in it forever, switched to 'high mileage' -- no change. Put in conventional -- no change. Owning two diesels, my eye quickly turned to the
Cheap WIX oil filter used, the slightly bigger one for Camrys.
Yes, this is way too thick for an engine that Toyota specs for 0w20 in later years. But the wear metals seem to say all is ok. Guess the parts are barely touching anymore ;-) ?
Not sure what to make of the Sodium, low enough to not worry?
