Use this in my both my 93 and 01 Harleys... air cooled but bikes run a lot smoother and shift fantastic!! Great product!!!

I use this in all my Harley m8 oil changes. I have noticed a slight temperature drop in my oil heat. For now this is all I want in my scoot. Worth every penny in my book

Extremely great oil v-twin rides a lot cooler than previously used Mobil 1 Actually just purchased Amsoil transmission oil for my Harley which I will review at a later date

Great quality oil, the extended range also saves on oil changes

I am completely sold on this product. My bike runs excellent and no evidence of wear

Made engine quieter.

I use it in my Harley Davidson 110 CVO Twin cam, and in my 117 CVO Milwaukee 8. I have been running Amsoil for years and have never had any internal oil related issues. West coast summers get really hot out here where we are, and SoCal traffic is the worst, but with Amsoil in the oil tank you don't have to worry about what is going on inside your ride.

Engine runs quieter

I’ve been using Amsoil in all my Harley’s since 2004. I believe this is the best oil you can buy.

Use Amsoil in both my Harley Road King Classic and my Daughters Sportster, wouldn't use anything else. Had trouble using Harley Davidson Synthetic, seemed to burn about 1+ quarts between changes. Not any more with Amsoil..

No muss, no fuss, great performance and peace of mind. Changed my oil every spring, ride all spring, summer and fall on the twin cam and Evo, no oil related failures. (Even the cam chain tensioner didn't look all that bad on the twin cam, replaced it though at 30k miles because I was in there making sure everything was on the up and up)

good stuff as always. wont put anything else in my 2014 ultra classic

I have always used this oil in my Road King custom and wouldn’t use anything else. As my bike is air cooled I like the idea of a synthetic oil versus a standard mineral oil. I feel it performs better especially in hot weather or when pulling my tent trailer.

I have always used AMSOIL SAE 20W50 in all applications of my Harley to include the transmission. I never had an issue with the SAE 20W50 but since AMSOIL came out with the specific transmission fluid I have been using it and I have even more confidence in the performance. I will use nothing but AMSOIL in all my vehicle applications. I have 4 Harley, 2 Big Dogs, 2 Trucks and 1 Car and they all use AMSOIL which is long lasting and the confidence in protections no other oil can give.

Great product I will use it again.

Works great, I run my bike hard for long periods of time between oil changes AMSOIL keeps my 2016 Harley Roadking preforming cool and efficient with improved gas mileage. Highly recommended this product. They also have outstanding shipping services orders arrive in most cases in 3 days. 😁

Although not recommended by any oil manufacturers in mixing weight in the engine oil, I am running half SAE60 in routine oil change. HD air-cool engines have larger tolerances in the internal working mechanism, this thicker oil works well for me.

Wouldn’t use any other product. Keeps engine running cooler.
