Everything you’d expect. Only thing I’d change is the amount per bottle seems like a lot of bike primary takes quarter or so of a quart so kinda annoying having to buy 2 or underfill….

Best in the business. Doesn't break down in extreme heat

Great product

Very little metal shavings on magnetic drain plug after 3000 miles so it's doing what it's supposed to do. Auto adjuster shows very little wear after 30 thousand miles

I use Amsoil on my 2017 Road King every 3,000 miles. Full Synthetic 20/50 engine oil, transmission and primary. Bike is friggin bulletproof. Thanks Amsoil!

Bike running like new

Amsoil in all 3 holes every time on the M8

Always what I order always on time

Shifts a lot easier and finding neutral is no problem

Good product, well packaged, very fast delivery

Change my primary fluid every 3000 miles with excellent results using amsoil product..! Thank you..

The best oil for a Harley V twin in my opinion.

This review reflects usage on a 2023 Harley Davidson Street Glide. From the time it was new, the clutch engagement was extremely erratic, causing the bike to lurch when starting out. It was very unnerving. In forty-plus years, I had never experienced such a thing on any other brand of bike. I was told that once the 1,000 mile service was done, it would be fine. Since I had a few warranty items to address, I had the dealer do the 1K service as well. Well, the clutch was no better. Finally after another 600 or so miles, I was fed up and decided to “re-change” the primary fluid and replace the brand new Harley fluid with Amsoil Synthetic V-Twin Primary Fluid. I noticed an immediate change in the way the clutch performs! The clutch engagement is much smoother and it is a breeze to find neutral. I highly recommend this oil over the OEM oil. I run Amsoil products in everything I own, from vehicles to lawn and farm equipment. This bike will only see Amsoil products from this day forward. P.S.- One tip – the manual states that the bike should only take 28 oz. on a drain-and-fill so one would think that a single quart would be enough. I needed a little extra to get to the full line. My advice is to buy two quarts. If you get away with one quart, great. But if not, you won’t be stuck waiting to get more.

Saves wear and tear on your clutch 100%!!!

I made the switch to AMSOIL full synthetic in all 3 holes and I’m hooked. I don’t see myself ever switching back to anything else.

Since using the V Twin Primary Fluid. My bike feels smooth and silky. It handles a lot better. First time using this product. I will continue to use only AMSOIL!!

take it right in and forget about it

This helps bike run cooler

Better than manufacture standards

It's synthetic primary fluid. It smells like chemicals, slipperier than ice on Interstate I-10 West.
