Well, this was the 3rd & final sample from my 20k mi M1 0W-40 long-term test. I feel pretty good about the results & would recommend this oil to anyone looking for a great, long drain, year-round oil in nearly any car.
Here are my previous UOA results for this run of oil.
The only Abby Normal occurance I can recall was a continuation of the PCV oddity. (See previous UOA comments.) After drilling out the port for the 4mm ID hose, the engine's resting idle was continuously high at 1200-1300 rpm. (Normal idle should be around 800-900 rpm.) Gas mileage improved slightly after doing this, so I didn't worry about it for the remainder of the OCI. I've now replaced the 4mm ID hose with a 3mm ID hose & the idle rpms have returned to their normal range.
Let me hear your questions & comments!
