Impreza had 18195 miles at OC. Is a DD with a good mix of trips less than 10 miles and between 11 to 50 miles. 80/20 split local/highway..
First UOA is on Castrol Edge 0w-20. Switched to Rotella 5w-30 Multi-Vehicle on second OC.
Personally, I feel the viscosity numbers as well as the TBN are encouraging. Other numbers meh but still young engine and believe next UOA will show wear numbers trending lower and possibly set benchmark for this particular vehicle going forward.
Added LM M0S2 to oil change back in August which explains the moly in this UOA.
Thoughts?
