Used this in two of my harleys Great product

Harley runs about 15-17 degrees cooler than other outrageously priced oils that say they are the “best”.

My Harley has used Amsoil since new at 90 thousand KM the compression is as close to what it was new ,transmission gears and chain show no wear at all mileage dictates it should need rebuilding but not even close Amsoil in motor, transmission-and primary have payed off big time I won’t use any other type of oil !!!

Performs as advertised. Ride 1600 miles in 7 days on Harley. Ran flawlessly

What can I say...this is such amazing, good oil better than any other ordinary conventional oil out there like SYN 3. Don’t take my word for it. Try it and use. You’ll feel the difference. Thumbs up!!!

I’ve used this oil in my Harleys for years and the thermal breakdown data speaks for itself.

This is an awesome product! I have been using Ams oil in my last three Harley Touring bikes. Bikes run cooler and quieter! I would not use anything else!!!

I have used this product since 2008 when I purchased my 2nd Harley it had 1500 miles on it. I put 97,000 miles on the motor. I bored the bike to 95 cubic inch. The bike still ran great just needed more power. Did not burn oil at all. Once apart Ring’s were a little sharp but not bad for that many miles. I swear by this product. Thanks Amsoil from loyal customer...

Amazing product we use it in everything we do just upgraded a 2018 107 road glide for cam and oil pump and the parts that we took out were flawless good oil works thanks Amsoil

I have been using Amsoil in my Harley’s since 2012. It is the best oil for my 2020 Harley CVO Limited!

Since I started using Amsoil I haven’t had to add any oil between changes. I was using about 1/2 Qt every 5K. Also, shifting into 1st gear at the beginning of a ride is much quieter now.

The absolute best oil for Victory. Keeps the engine Temps much lower when sitting in traffic and doesn't affect the clutch grip on the friction plays like most synthetic oils do.

This works good in my Harley and alot more cost effective than buying HD oil!

Use the best, rise hard

Only oil I use in my '13 Heritage Softail.

Only oil I run in my bikes. Runs cooler in the Texas heat.

So far so good. My Indian Roadmaster Elite seems to run and shift a bit smoother. I have not seen an increase in fuel mileage but I’ve only rode a few times.

I put over 20,000 a year on my bikes and have used Amsoil in all of them sense new . Never had a problem with the engine . transmission or the primary .

I have used this oil in my 2014 Indian Chieftain since I bought it. My motor runs about 10 to 15 degrees cooler. And it runs smoother
