Oil was in service from Oct 2015 until Dec 2016, utilizing a M1 EP (M1-209) filter. Mix of hwy and city miles, mostly hwy with lots of trips over mountain passes. I replaced with more Mobil 1 EP 5W-30 and a Fram Ultra (3614) filter. I last had a UOA done by both Blackstone/OAI labs (here) at the 51,000 mi mark. This was a heavy driving year for me so Ill probably stick with a 15k OCI.
