I assume that's straight motor oil? Motor oil can be used as a temporary substitute for MTF in manual Honda transaxles, but should be changed out for MTF as soon as possible. Motor oil lacks the conditioners that, amoung other things, keep synchros alive and well. Honda MTF is like $3 a quart, and you only need (less than)3 quarts every 30k miles or so. I would not skimp on MTF.
Good call. That's exactly what I was going to say.
