honda guy,
if the manual says 10k, and the mobil1 meets the honda spec, go for 10k with an analysis done at 10k, if you are worried. honda is pretty conservative on their change recomendations (my insight still carries the 3500 mile severe service recomendation, and that's what my lifetime oil changes at the dealer i bought it from are done at and boy are they going to regret that sales gimick before its over), and they know their engines better than any other manufacturer,IMHO.
if the mobil1 doesn't meet the honda spec, drain it out now, even if you have to tow it to the dealer. the honda 0w-20 is the only oil that is imported from japan that my dealer has, and i would guess that makes it a little special.
