Friend just bought a 2011 odyssey(190K klms) with 3.5v6 that is a bit of an oil burner, 4L in 5k klms. 0/20 is what's called for, has anyone bumped up to 5/30 and seen a drop in oil consumption? I know thats no fix for stuck rings( i assume....pcv is good and clean), just wondered if anyone has been down this road.
