Ive been a honda guy for along time and its a general rule with hondas, dont switch to synthetic oil after you buy a high mile car. vtec loves to burn that oil.
I just bought my 02 wtx, about to do a oil change.. I asked the old owner if he used any special oils.. he said no so I figure its dino in there. any reason to not go with synthetic? i really dont like moble, will prob go with castrol either way.
