Customer Ratings & Reviews

Bought the bulk containers to see how alternative container works. It is better for storage but adds a second step when changing oil. Funnel into engine needs a slower steady rate to prevent overflow. Easier to pour into measuring cup and adding oil. Will probably go back to quart containers.

Very good Oil would would definitely recommend it

My 103 loves this stuff. I will purchase again.

Great oil with top-quality performance. My bike runs smoother with this oil than with any other brand I’ve used. Even after long rides on hot days, the engine stays quiet and I don’t get the ticking noise from heat that I experienced with other oils. I’ll continue using this oil for the life of this bike and any future bikes I own.

Kit comes as a full package, including gloves and funnel. Did not get the free tire pressure guage that was promised.

I use this for my 23 Indian springfield dark horse. It works great. Shipping is fast and accurate

Swapped to AMSOIL from factory oil. Seems like a good choice so far.

Actually better than Sliced Bread.

Again have used the Harley SYN oil in for years.. I have a 2012 Road Glide and made the change.. Engine quieter.. more oil pressure and runs great.. And a better price as we’ll.. A NO brainer ….

I got this for my recently purchased 2012 HD VROD. I've heard good things about this oil for V-Twins, so I'm looking forward to trying it out. The service was great as well - everything was well packed and arrived quickly.

love the products been running them for years 94,000 miles on my 15 Harley FLHTK no problems wish you had the filters in stock

Parfait pour mon Harley

Excellent oil and I use it in my 08 Road King. It gives me a peace of mind knowing that the oil can withstand the heat the engine generates.

Great product. Will purchase this and other AMSOIL products again soon.

Best car soap I've ever used and I've used alot.

Best oils I’ve used in my 04 fatboy. I’ve used it exclusively in this bike since I got it. Every oil change. Okay, so I got this bike for my birthday 11 months ago from my daughter and this is only the second oil change, but still.

Smooth oil that keeps my Indian running cool

Been using Amsoil for over twenty five years. Insides of the motors looks new.

I run this on my 16 Fatboy lo s with a 110 screaming eagle and I really love it

I have the Figurati Designs magnetic dipsticks on my 2022 road king special. Im at my 2nd fluid change with Amspil, away from Syn3, there is noticeably less debris on my dipstick magnet this 2nd time around. Perhaps its because the engine runs alittle cooler (FP4 gauges on my phone mounted on the handlbars) or the sheer strength is much better, I don't know but its damn near clean after 1000 miles. On my first ride, after switching over the first thing I noticed was I couldn't hear the metal ticking noises at a red light anymore. So that's interesting. Im assuming theres better metal adhesion.
