many of us have a favorite oil we use for whatever reason. I prefer to use Chevrons Delo 400LE 15w40 and if not availiable I will use Shells rotella T 15w40. Both of these are SG or CJ rated oils for diesel engines, higher rating than is required . I find that the Delo makes for smoother shifting and easier to find nuetral.
Oil is one of those "favorite " hot topics .every body has an opinion on the matter. Generally most everyone agrees that using an oil with friction modifiers (moly) is to be avoided as it may cause your wet clutch to slip. Type "Oil" into the search box and you will have many hrs of reading availiable to you.
The key is to pick a quality oil and change it as per mother Hondas recomendations
