The place where I get LM from, they dont have it. I just get it from the honda pit stop or dealer that is near my work place.
About 10k, well thats always a debate. This is a good quality oil and a lot of people who have been using it here do to for 8-10k drain intervals, yet to hear anyone complain that they have had issues. I have used it for the last 30k (currently at 152k), so 3 oil changes. Engine runs great still (not that it wasnt with honda oil). Winter starting however is smooth with this oil.
