Been using Amsoil in my bikes for years. Never had an issue. I only wish Amsoil would sell crush washers too. That would save me the trouble of having to order those from somewhere else.
Bottom Line
Yes, I would recommend this to a friend.

Changed oil and filter when it was scalding hot. This was my 500 mile break-in maintenance and am confident as many little metal shradswere flushed out. The smoothness in shifts and the tightness in revs sounded better. This oil is superior. Glad AMSOIL exists. Will only use these products from now on!
Bottom Line
Yes, I would recommend this to a friend.

Oil for My Indian Chieftain
By

Purchased a used Indian Chieftain with 6K miles. Been using synthetic oil in my cars for decades. Decided to go with Amsoil due to all the great reviews on the Indian forum and good wear analysis reports it gets. Dropped the oil at 7,500 and replaced it with 20W-40. I noticed that the shifting seemed smoother and the heat from the rear cylinder was less. I don't have any measurements other than the seat of my pants. I just passed 11K and changed the oil again. The old oil looked fairly clean, and 5+ quarts came out. My next change will be at 15K, and plan to send off an oil analysis to see how the engine wear is doing. So far I am very pleased with the oil and how the bike runs.
Bottom Line
Yes, I would recommend this to a friend.
