The two are both high quality oils. Vtwin 20-50 for engine, MTL or Primary oil, and Redline Vtwin Transmission with Shockproof

Lots of riders do just that and swear by it. Personally, I prefer using Syn3 in all 3 holes. Works just fine for me.

See reply #1…

There are lots of comments on oils.
One of my club members only uses the cheapest Walmart 20-50 engine oil for all 3 holes and his stock bike runs just fine.

My personal bikes run Mobile 1 v-twin 20-50 in the engine, redline in the transmission and HD in the primary (I have to shop at the HD sometimes due to these gift cards).
 This combo works for me and the engine parts shows minimal wear after many miles.

Of course mix brands if you can't get all the same. Mobile 1 is also very good oil. Lots of room at the top for good oils. Engine oil I prefer a full synthetic.
