Customer Ratings & Reviews

Have been using AMSOIL in my 2006 HD Fatboy since I purchased it in 2009. I also use AMSOIL in my 2007 Tundra. Oil in HD gets changed every 5 to 6 thousand but has gone longer but with AMSOIL I don't worry. I order my V TWIN oil change kit every winter so when spring riding weather hits I can have a fresh oil change ready to go.

Great product

My Harley does not overheat and I do not hear any funny noises since using this product. It seems to be doing its job.

Been running this along with trans fluid and 20/50 oil in my 21 year old Harley with 98,000 + miles. Change every six to eight thousand miles. She’s running like a champ - No leaks and no major repairs, can’t ask for more.

I use Amsoil in everything else !!

clutch and gears work better.great product for harleys.

As it states on the bottle, its primary oil. Does its job and does it well. Run it in my buell and harley now.

Been using all types of oils for decades. Amsoil always performs the best.

Amsoil is the only oil that I use in my Harley Davidson

Have been using this in my Harley Davidson. Switched to it due to riding my bike on long distance rides (1000 plus mile days). Really love the way this stuff has worked so far.

Solid product have used for many years

I use nothing but AMSOIL in all my vehicle's to include primary fluid for my Harley's and Chopper's. Before AMSOIL came out with Synthetic V-Twin Primary Fluid I used AMSOIL Synthetic 20W50 oil which is the same as I used in the motor which performed great but now I used Synthetic V-Twin Primary Fluid. It gives me the same confidence as the AMSOIL oil I use. Great products as always.

I do all my own oil change services on my Harley’s and this is what I have been using since my first service on my 2018 and 2020 Road Glide. I have no problems with finding neutral, and have used it 10k on the 18, and 10k on the 20 so far. It’s very quiet with no trans noise and that’s in Daytona bike week heat traffic. Just like the V twin trans fluid, great.

Primary clatter is quieter.

I've done my research and noticed the results , I only use amsoil products in my vehicles

Outstanding product, have been using Amsoil for years in my Harley Davidsons without any oil related issues.
