Was time for an oil change, and have been using AmsOil products in my truck since 2016. I've tried other oil products in my truck and have not liked the results. Harley-Davidson does make a good product for their bikes, AmsOil just does a better job especially during warmer climates or heavy traffic when oil breaks down faster. I recommend trying it for a couple of oil changes then returning to what you used to use. If you can hear a difference then you know you made a good decision with AmsOil.

The Best

I only run Amsoil in my Harleys. All models, all years. I trust Amsoil above all others.
I’m here to say that after years of waiting, I’m finally able to get all my fluids from one place and the quality is top notch.
After making my first purchase for two motorcycles and one car I will definitely be making my purchase for my remaining vehicles and my tractor. It’s a one stop shop and it’s delivered to the property. My only complaint and it’s not a deal breaker is that I put a code in for free shop rags that were not sent. Maybe I messed up since I’m not tech savvy.
Also, if you spend $500 in a year, which's not hard.. you don’t pay a membership fee. Switch to Amsoil.. Today.
This oil from AMSoil is the best lubrication for Harley big twins in my experience. Over 50 years of riding Harleys, and these products are the best I have found, and I have tried several synthetics. None has performed as well as AMSoil fluids do. The engine noise is noticeably reduced and the it runs a little cooler, as compared to HD brand synthetic oil. The noise reduction impressed me, didn't expect that at all on my low milage twincam. (Valve train noise mainly.) I highly recommend AMSoil fluids for your Harley. I also use the Primary and Transmission fluids formulated for each component. Absolutely top notch performance and protection, none bettr!
Bottom Line
Yes, I would recommend this to a friend.

After I put Amsoil in my motorcycle, it runs so smooth with shifting. I am now 100 percent Amsoil, and when my truck needs oil change I will put Amsoil in it as well.
Bottom Line
Yes, I would recommend this to a friend.

Smoothing Out My Thunderstroke Engine

I was curious what switching from Indians 20w-40 semi-syn oil to Amsoil 20w-40 full syn might do to the operation of my Indian Chieftain 116 Thunderstrike engine. From the first ride, I was surprised that the engine ran with less vibration than before. It was also about 50% easier to find neutral (the worst of any bike I have ever owned in 50 years of riding) than it used to be.
Cheaper than Indian's oil too. Try it. You will not regret it.
