This is the only oil I will use in my 06 Street Glide. I have over 70k miles and running smooth. You can even use it in all 3 holes on your bike. I’ve done this and have lower operating temps.

I was using redline oil and I did some motor work and the AMSoil makes it run cooler

I'm very happy with this oil. I have a 110 with 65,000 miles and it runs cooler and quieter

Awesome oil!!!! All three of my Harley's love it.

I have used this oil in 2 Harleys. Never had any issues. Just can't see using the same harley oil in all 3 holes it just doesn't make sense to me

Harley Davidson maintenance , using for 160,000 + miles, bikes running great

Great oil great customer service. Awful courier service used please never use Loomis express to ship your product showed up weeks late

After trying all the other oils amsoil did the best job for my purpose I use it in all 3 holes of my Harley

Once I made.the switch a year ago, never use anything else! My 2016 street glide cvo runs smoother and cooler. I will always use this oil and switching my cages to amsoil now.

Used this oil for 50,000 miles. Eng run cool and uses 0 oil. I would recommend for any motorcycle

Oil works great. And I like I can order it is at my front door in a couple days .

I started using Amsoil V-Twin oil last year based upon the recommendation of my engine builder. I am using it in both my HD Ultra Limited and HD Road King. No issues, bikes run clean. Delivery of my orders is fast and flawless!

I used the Amsol’s 20w-40 oil in a customer’s Victory Hammer S with a 116 big bore kit. The bike ran significantly smoother after changing the oil to Amsoil. I use Amsoil in my personal dirt bikes but normally use manufacture’s oil on my personal Harley V-twins motorcycles. I’ve been a fan of Amsoil for awhile and use it on customer bikes when requested but normally stick to Harley brand oil out of convenience. Next oil change on one of my own v-twin is going to be Amsoil!

Great oil period.

Only Amsoil full synthetic for my 2021 Milwaukee 8. It keeps the engine quieter, runs smoother, and keeps the engine cooler.

Always used Amsoil in my Harley. IT doesn't break down from the heat generated in NY traffic. Also it provides maximum protection at high speeds.

I have a 2013 Victory Vision. After using this oil I found shifting smother. Also after 10,000 km (6,000 m) the oil still looks and feel good. Yes I am hooked!!!

Great oil

Great product. Fast delivery. Good price. Will order again & again. I run 10000 miles before I change oil on my 2001 HD Electraglide Classic. I use it in the primary and transmission also. Love it.

Been using Amsoil since 2009. 110,000 miles later, still using Amsoil and my engine still runs like new. Thanks Amsoil!!!
