Well, I'm changing ht eoil in my Ex V6 tomorrow at 3200 miles. I used
to change it at 2000 the first time. My Honda dealer has its own
maintenance book at is recoimmending the first change at 3750 for $12.
Of course, they want to make money... but I think the prudent thing
to do is stick closer to 4k-5k than waiting until 10k. MTFWTAW.
