This one run ~4800 mi., 13 months from 1/22 on Honda 3.0L w/Magnatec 0w20. Quaker State Full Synthetic (no longer Quaker State Ultimate Durability) 0w20 and another US made Bosch Prem. 3323 went back. Used many of these recently, typical results. Got two 6 lot shipments from RA, ~$5 each including shipping, before recent change in coo. Silicone adbv pliable. Satisfied with results here again.
