I'm running Mobil V Twin in the engine and Redline Shockproof in the primary and tranny.
Amsoil breaks down too fast in the heat. There were many stories on here last summer of people having problems and alot of noise with Amsoil.

You're new here, aren't you?
As said above, this is the most beat-to-death topic on this forum. Do a search, perhaps in the oil specific forum, and you'll get more information than you ever care to know on this. More conflicting opinions and misinformation also.

There is no right or wrong answer to the original question - only opinions.
That said, I run Mobil 1 V-twin 20W-50 in the engine and primary, and Mobil 1 75W-90 or 75W-140 Gear Lube in the trans on my new Limited.
My Duece has always had conventional HD 20W-50 in the engine and Formula+ in the primary and trans since it was introduced. Prior to the introduction of Formula+ I used HD's primary and trans specific lubes.

Like he said above you won't go wrong. I personally have used Amsoil for the last 12 years. 20W50 in the Primary & engine and 75W90 in the tranny.

I've tried the HD Syn 3, Mobil 1, Mobil 1 V-twin, Amsoil, and a
couple other synthetics that I forget their names.......
I'll change oil and filter at 5k ..... about the only difference in the oils
is cost, and availability to buy a qt if you need it while out on the road.

+ 1 Redline
available here in the USA - too much stuff in it the EPA doesn't like. That said,
they all recommend Redline - so that's what's in mine everywhere - their primary
oil too.
