      Oil for My Indian Chieftain
      By  DDR,  a  Verified Buyer  from  San Ramon, CA  on  August 13, 2026
      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.

I will never go back to syn3 I will have to see how it does when the weather gets colder on these chilly mountain morning but for now I am loving it.
