Customer Ratings & Reviews

Great product! Been using it for years

Helps improve shifting noticable .

I was originally using the severe duty 75-140 transmission lube. After switching to the synthetic V-twin , I have harsher shifts and a harder time finding neutral.

best oil i have ever used, i use it in about 30 motorcycles that i service in my town,

Use it in my 2019 CVO Limited. Shifts smooth and also quiet, no loud clunck. Easy to find neutral.

I have a 2015 Street Glide and it shifts better and seems to be quieter . Great product.

smooth and more silence shift

Better then OEM

Used in my 2003 Night Train, great oil!

NOthing goes in my Harley but Amsoil!

Only oil i use in my bikes

You can hear the difference when shifting!!

Definitely mad3 shifting quieter...

I chose to use the transmission fluid even though I could use the 20w50. Very little vibration with smooth sifting.

Seemed awesome

Swapped recently acquired HD Tri glide to Amsoil, used to have to shut it down to get in neutral, now drops right in. Great product.

First time I purchased,worked very well just like Amsoil always does

This is the first time I've used anything other than Amzoil 20/50 motorcycle engine oil in the transmission of my 2013 Harley Davidson Streetglide. I noticed right away that it shifts smoother. Especially after the engine and transmission are running at their full operating temperature. When I'm at a stop light and idling in neutral, If I pull in the the clutch and if I hold it for a couple seconds before shifting into first gear and it just slides right in as smooth as ever and doesn't even make a noise. Overall it just shifts smoother, I'm glad I took a chance and switched to this.

I have been using Amsoil for a long time on many different motorcycles. Amsoil has a keep it simple process, if you need oil for engine, transmission or primary just order for that specific place. Always the same quality performance oils and I've never had a problem. Thanks much!

Only the best!
