RE:AMSOIL
I just bought a 2022 Street Bob with the 114 engine. The dealer did the 3 hole oil change and said they only use 80W140 oil in the Primary now. They said Harley stipulates all newer Harleys use only the gear oil in primary.
I looked at the bottle and it is not even a full synthetic, it is a synthetic-blend. I am coming from a 2012 Fat Boy and a 2011 Heritage Classic, where I only used Amsoil Primary oil in the primary.
Anyone know why Harley made the change?

The 80W145 is a good move for the primary. HD made a wide choice when they moved to it. If you read up on why HD did it will ease your concerns.
Why is simple better lube for the Job. F+ was ok is is a 50w. 80W145 is more along the line of a 20/50 engine oil. It protects better at both cold and extreme temperatures. Keep in mind Engine oil and Lubes like 80W145 are measured in different ways. When same method is used the 80W145 and 20/50 come out pretty much the same.

Where can I find that information?
I have been using 80W/140 for several years. I think it workds great. A old timer , both age and years of riding still says the 20w/50 for all 3 holes.
I'd like some facts?
