Customer Ratings & Reviews

First started using Amsoil in my ‘01 Dyna and since 2015 on my Ultra Limited. Change my oil every 5k and haven’t had no engine problems at all. Runs Great!

Highly recommend

Best Synthetic V-Twin oil for your Harley, great Amsoil price.

Really like this oil. A bit high in $.

I prefer to use dedicated oils for each part of my bike. It’s nice to have one convenient location to order with fast shipping.

For me it’s hard to tell one primary fluid from another but with this stuff it seems to be easier to find neutral and I don’t get as much primary noise.

great product

Always protecting clutch and internal parts for smooth shifting

Change it every other oil change versus every time with oil in primary. Better protection and performance and saves money due to fewer changes. I have nearly 70K on a Harley and she don't smoke, clutch work great, and the tranny is solid, I use Amsoil for all three Engine, Primary and Tranny and I use Amsoil filter too.

This primary fluid is soooo much better then the Harley brand. I will never use anything but this in the future!

Always use Amsoil Tran product. Excellent!

I like how Amsoil offers an oil for each hole in my Harley. And their online selection tool makes it so easy to get the right product.

I use this in the primary on my Harley. I definitely push it hard and the clutch is still good

This product does what it says smooth quiet operation makes it easier to find neutral great product
