I have been using Amsoil in my Harleys since 2004, running in cold and extreme heat. Bottom line I trust it can’t ask for more than that.
Bottom Line
Yes, I would recommend this to a friend.

I’ve been a Harley mechanic for over 40 years and used all of the top name brand oils out there.
Besides using Harley’s conventional 20/50 oil for new motor break ins, I haven’t found a better oil than AMSOIL Synthetic 20/50 for “after break in” use.
I’ve pulled down motors ran on AMSOIL and the parts after thousands of miles show very little wear.
I’m such a fan that I switched my diesel, my Porsche and my wife’s Grand Cherokee over to AMSOIL.
Bottom Line
Yes, I would recommend this to a friend.

After daunting research about oil, decided to go with Amsoil. Glad I did, could tell an immediate difference. Not going back to the “old stuff!”
I have been using Amsoil products for a few years and all of my clients truly live it. They often comment on how better their Harley run since the switch to Amsoil!
I’ve been using these kits for my bikes for years and you can’t beat the price compared with buying individual quarts and plus you get the correct oil filter and the replacement O rings needed for the change.
Bottom Line
Yes, I would recommend this to a friend.

Found it was a noticeable upgrade from the previous fluid. That being said the previous fluid was what was in it when I got the bike and was due for a change. Shifts slight but noticeable improvement in feel and sound.

Best oil I have used in my Harley

My bike runs great with AMSOIL. Seems to run smoother than before the oil change. Very happy with all the AMSOIL products
Great kit for your oil change needs. Comes with 4 quarts of oil, a oil filter and an o ring. This is the only oil I will use on my Harley Davidson motorcycles. Priced right, its a huge savings changing your own motor oil. Very highly recommended.
Bottom Line
Yes, I would recommend this to a friend.

Always wanted to try this on my bike, I had just done a three hole oil change from Motul in the beginning of the summer but i wear willing to change it again just because of my curiosity and i couldn’t be happier, I had redo all three hole with Amsoil and the first thing I noticed was my bike run cooler so less heat between my legs that was amazing!! It’s Amsiol for me from now on.
