This is not a how to article.
It is a listing of current (2014) part numbers for a genuine Honda oil & filter change on the ST 1300.
Oil weight is 10W-40. WITHOUT MOLY!! API SG or higher. (API= American Petroleum Institute) API ratings alone are not the best choice these days for selecting your oil.
Honda uses the JASO (Japanese Automotive Standards Organization) ratings that are much more strict than the API ratings we used to use for selecting an oil.
Honda recommends JASO 4T (4T means four stroke) service classification MA. (MA= engine & gearbox in one unit. Fluid is non-friction modified "no moly")
The Honda service manual lists two oils that can be used in the ST1300 if using genuine Honda oil.
GN4 ( Basic petroleum stock, no moly) PN# 08C35-A141M01 (1 Quart) Been used & recommended from Honda since 1975.
HP4 ( Synthetic blend) PN# 08C35-A14WOM (1 Quart) Notice the "WOM at the end. That means without moly.
Here are a couple pictures of 1 Quart oil bottles. The one one the left is an older bottle from Honda. The one on the right is a new bottle (2014) from Honda. Little bit deceiving if you have some older bottles since the new bottle does not say "without moly" on the front
Notice the new bottle on the right does not have the words "without moly" on the front. It is the correct HP4 oil without moly The part number is the clue. 08C35-A14WOM (WOM means With Out Moly)
Here is the back of the two bottles. New (2014) bottle is on the right.
Now, we are going to get to genuine Honda oil filters. If you go to all the on-line parts stores, they will list about 2-3 genuine oil filters for the ST1300.
