Didnt realize the sound coming out of the primary with worn fluid….. much quieter operation now

I’ve used this a few times and it seems like it works well. Fairly confusing figuring out if this is any better than the 20W-50 V-Twin oil for my HD. I think I’m going to try that in all 3 holes.

Quieter primary after changing over to Amsoil

Shifting is so smooth and easy

Good product

lots of people recommended this product so far is doing it's purpose

After seeing how the oil and trans made such a difference I know this can only be beneficial now that Iam running it also.

Been using this in my closed primary HDs for years and it’s great. You can feel the bike running smoother when you change the fluids. Some of the older models say you can use the same fluid in all 3 holes, but why do that when THIS exists??

Good oil

Disappointed. I love Amzoil and most of their products, but this one just hasn't seemed to keep up with current practices. Even Harley has come out with a new updated Heave Duty Primary Fluid, and the 80w-140 range. But Amzoil has not. They don't even list the viscosity on this old oil. Time to get a new Heavy Duty Primary Oil out there, Amzoil. A lot of us v-twin customers are waiting for you to update and come out with something better than Harley.

I have a '24 Softail Heritage 114. I changed the motor, trans and primary at the initial 1,000 miles. I noticed smoother engagement and smooth shifts.

Awesome fluid and great value

Spring time change

#1

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
