Kurtatron, Use the Amsoil if you have it already. Its good stuff, good reputation. It's CG-4 is too old for your 2017 **technically** which probably doesn't matter to us, and I hope Harley would see it that way. ...
If you really want to preserve your warranty, use the "other" Amsoil 20w50 that rubberchicken above mistakenly thought you have. (You have the V-twin 20w50.) Maybe you can exchange your V-twin version for the correct Amsoil 20w50 that has the right certifications? If its easy to do.
In the future, after the Amsoil, Rotella T6 15w-40 meets your Owner's Manual requirements, and is a great oil too.
Walmart has it I think. Should be reasonably priced and well engineered, full synthetic, checks all the right boxes, good company Shell is.

I got it right, see above. CG-4 is too old a spec for a 2017, formally speaking. ....

Thats the most popular stuff to use, possibly.
Amsoil 20w50 has a similar old-spec problem too.
As long as the oil has
CH-4, CI-4, CJ-4, or CK-4, any one of those, printed on it, then its OK with Harley, and thats a bunch of diesel oils at walmart.
This is the Amsoil ratings, so it meets the requirements.
API SL, SJ, SH, SG, API CI-4+, CI-4, CH-4, CF, CF-2

You are looking at the wrong oil for this thread. The Harley V-Twin variety is

Neither of those oils qualify for what Harley asks for. Like you, I think they're great. Harley doesn't agree with us.
