Like i said I've always used Amsoil 20W-50 in all three, engine, transmission and primary. The owners manual only says Formula Plus in the primary. I did call two local dealers, both said Amsoil 20W-50 is fine for the primary.
At this point, I think I'll just use Formula Plus and switch to Amsoil 20W-50 later.

i've always ran mobil v-twin in the engine and primary with redline in trans. no problems yet. on this new 15 trike i used formula + in the primary for the first change just because i had a quart and a half sitting on the bench that someone else gave me, so i used it. next change i'm putting the mobil in.

According to "Bob the Oil Guy" forum, Formula Plus is just 50 weight oil:
Formula+ is nothing but a 50 weight oil. Nothing special about it.
Harley-Davidson Formula + ( Virgin oil analysis* Blackstone Labs)
Petroleum based. (Made by Citgo)
Ca 169
P 230
B 210
Zn - none
No other elemental additives.
Viscosity - within SAE 50 range.
Listed as a GL-1, does test out as a GL-3.
I'm going to use the Amsoil 20W-50, I'm quite sure it's better than Formula Plus.

2-12 of the service manual states you can use Syn-3 in all 3 chambers. However do not mix lubs

That is the way I go. With the only exception, I use plus in the primary. They have been using this stuff forever, I have never had any problems. And I still just pour in a quart and call it good.

Is that the 2017 service manual? I haven't ordered mine as of yet, I need to get on it!
