How much oil what weight and what # filter should i use to change the oil in my 400 forman

 

can anyone help?

 

The oil filter is the common honda filter. same one your old 400ex used. The fram number is CH6015,or the wix number on the filter is 24944
Unless its gonna be real cold, use 10w 40, SG rated, non moly oil.
For how much, use the dipstick, but remember to just have the dipstick resting at the top of the hole, and not threaded in , while checking the level.
