My latest UOA.
Down to 50% OLM.
drained 4.5 qts out of 5.5
Im still using my favorite- regular cheap Valvoline Dino 5W-30 that I buy at Wal Mart for $16 and the PF-48 also available at Wal Mart.
this oil say use during June, July, August- daily commutes.- 3000 miles worth.
The last 2000 miles was my trip from Los Angeles to Denver for Labor day.
I did use L3,L4,L5 to climb the Rockies- and to use the engine braking going down the hill.
I did this UOA- to monitor for elevated iron-- which could point to a timing chain issue...
But appears theres nothing to worry about.
