what grade oil for engine/gearbox/diff ?
according to the FAQ its 10W-30 (or 10W-40), 75W-90 GL-5 and 5W-80 GL-4 for engine, diff and gearbox, respectively. i think the honda recommended 10W-30 is pretty rare though, none of the big guys seem to sell such a grade! if you're lucky like i was you might find a garage with a gallon or two spare!
