The special Primary fluid is worth the extra couple of dollars. Bikers to shift more smoothly and quieter. I will not go back to the same oil in all three holes.
Been using this oil for years on my bikes and friends of mine with never any problems will continue to use this oil also use amsoil in both my trucks thanks for a great oil
Bottom Line
Yes, I would recommend this to a friend.

I have been using Amsoil for 25+ years in my motorcycles and it is simply the best oil out there. I have left comments on nearly every oil produced for bikes. I bought in 2022 an Indian Super Chief and it requires 60 weight, and this is the perfect solution. I have never had any engine failures in all the years I have been using Amsoil.
Great product. Have been using in my bikes for years. I always tell the story that my shifting issues (finding neutral) went away on my 1995 Heritage Softail when I put Amsoil in the primary!
I switched to V-Twin 100% Synthetic when I found out HD Syn3 was a blend, I was told from friends that Amsoil would make my engine sound a little rattlie but I didn't notice a difference, I did notice that my shifts were smoother and super quiet. I use it in my primary and trans too. I'm planning on switching over to Amsoil on my other Harley, 2008 RK CC Twin Cam next. FYI- I usually buy 4 gallons at a time and they fit perfect in the supplied box.

Excellent product with a great value. Shipment was fast and convenient working through the website. I would recommend and have a recommended to my friends.
Amsoil has proven the best under high temps Harley air cooled engines run at without breaking down. I sample my oil and always find it free and clear of contaminants. Excellent product and worth the price. Best preventative maintenance you can do change frequently.
This oil is solely to be used in the Indian thunder stroke motors, reasoning is their's a additives for the clutch that makes a noticeable difference.
Bottom Line
Yes, I would recommend this to a friend.

Best decision ever

I wanted something new for my 24 street glide and this oil change was spot on. My oil pressure is perfect and everything was spot on. I’ll be a permanent subscriber to amsoil
I have relied on Amzoil for my motorcycles and cars for years, so I knew it was good stuff. I recently bought a 2018 Harley Heritage Classic and it needed a 3 hole oil change badly. Having never owned a Harley I did some research on different oils and what people use for the different locations (primary, gear box, engine) and after doing this, I decided to go with Amsoil V-Twin for all three applications. I can tell you the bike loves this stuff. The primary and gear box are shifting much smother after the oil change. So I will stick with this until I sell my bike.
