So: I finally got my Haynes Service manual and am getting set to do an Oil change. Couple Questions: 1: I was expecting to have to do an Oil Filter change, as well as just the Oil: but there is no mention, whatsoever, of an oil Filter that I can find in the Oil changing Section. What am I missing? 2: I recently heard that Motul 5100 10W30 Engine oil is/was designed for Honda Engines, at least they go into most newer models when put into Servicing at a Honda Dealer or when new: Would this be an acceptable Oil for my Older Bike? If it is not, what would be a recommended one? I am currently using Motul 3000 SAE 20W50, as it was given to me from the Previous Owner: i was orginally just going to get the same, as there is not enough for a full Oil Change left in the Bottle.. which also looks prety old, so not sure if using it would be a good idea anyway. Thanks for your time!
