Customer Ratings & Reviews

This trans fluid is amazing within a short distance I could feel the deference in the way it shifted and finding neutral was much easier and just got better with time.

Its the 3rd case ive bought and am happy with its results .

I purchased my first Harley in 2008 and have used nothing but V-Twin since and Ea filters since. My bikes have never engine transmission problems or run too hot.

Switched from Victory (Polaris) branded oil to this Amsoil product 3 years ago. The bike runs a little cooler and oil seems fine throughout riding season. Haven't had any issues with shifting either as the gear box on these bike share crankcase oil.

Great oil! Great company! Oil I can trust!

Great trans fluid. I wish it had some color to it because it stays so clear it's hard to read on the dipstick

This oil is amazing, I bought a 2016 street glide, the thing had regular Harley oil in it when I bought it, changed out everything, the engine, the transmission, and the primary, it starts up easier, I can get it into neutral a lot easier, it’s a different bike all together now, guys try this oil in your bike, you won’t be disappointed

This is the first time I’ve used Amsoil. This has been a low mileage season but so far my ‘02 110 stroker motor is running about 30 degrees cooler and the valve train is noticeably quieter!!

Awesome product so far! Quieter tappets in my Sportster for sure!!

Switched to absolutely versus Indian oil . Definitely made a difference. Not as much chinging in the motor .

I’ve been an Amsoil customer for quite a few years now simply because they make a superior product. With the independent testing and the extended oil change intervals, it’s a win win.

Engine runs cooler and quieter

I got this oil to use in the summer months. From June to September in South Carolina the ambient air temp. can be 85 to 100 degrees. HD says to run straight 60 for ambient temps. over 80 degree. I believe this will help the oil temp. stay around 230 degrees thusly making a happier M8!

Was getting ready to do a top-end on my 65 Pan, wrenches in hand, when I checked the Net to see if anyone had come up with 60W synthetic. The Pan smoked a bit and ran poorly when hot. I ordered some AMSOIL 60W and received it in one day. Emptied and flushed the oil system with about a quart, then filled it with the usual 4 quarts. Now I still need to do a top-end someday, but for now, the Pan is running superb. No smoking, higher oil pressure, running cooler and smoother and easy starting. I didn't expect this much improvement.

Put this in my Harley for the first time and notice a difference right away. Trans shifts much easy`er and primary not as noisy either. everything is running smother when ya come right down to it. Like it so far, will use it from now on in all 3 holes. Thanks
