I've used this in my Yamaha since new. 109,000 miles later it's still running strong. After cheking the valve clearences recently everything still looks pristine!

I've been using Amsoil synthetic metric motorcycle oil for years in all my bikes, from a 2003 Yamaha FZ1 to a 1966 Norton Atlas.

I bought my bike used with 38k. Now 124k and it just runs awesome.

I recently did the valve maintenance on my son’s Kawasaki 1400, which he has been using Amsoil in with a K&N filter. I have been working on engines of all sizes and fuels for over 40 years. The engine on the Kawasaki was super clean and had no wear issues on the cam journals. The internal engine parts were clean and slick but not oily. I definitely contribute the condition of the engine to Amsoil full synthetic. Now I am going to change my V-twin Harley’s to Amsoil V-twin synthetic.

Works great and the oil is holding up great

I have been using this oil for 30 years in all my motorcycles. It works great and I have never had an engine problem during that time. Definitely worth the money

I use amsoil in my 75hp carburetated out board. I firmly believe it keeps my engine clean and smooth running. I troll a lot with this engine (4-6) hours per outing. I check my spark plugs regularly and the results is they are clean and burning properly

I use Amsoil Full Synthetic and a bottle of Lucas oil additive on my 2019 M109-R and the engine/gears shifts so much smoother. I added Lucas after a lot of research and from what I've read and seen and it sticks to the metal giving it protection during start up, plus, my bike burns oil if I don't use Lucas.

Down side is change Interval is the same.

Excellent clutch feel and response. The hair bit more aggressive than your MA1. The main thing I feel is a quicker response than the MA1. I use this in all my wet clutch machines

i have used Amsoil since 2003 in my Yamaha Royal Star Venture 1300 cc i put 137000 miles on it never had to adjust valves never had any engine problems . now i have a 2018 BMW k1600 and using it again . love it

Received this order fast😎

I operate a Honda Goldwing only shop, I have used your product for many years, never had a single oil related issue with all the bike serviced here.

Good fast service. Works well for me.

Very quick delivery during the holidays

Good oil. I wish that you sold oil filters also. I've had to source Royal Purple oil filters since you don't stock oil filters.

I just picked this bike up a Kawasaki concours 2016. This is my first oil change with amsoil and already I hear the motor running quieter! To me. That's win-win. Win-win! I will definitely keep using this. I use it in my side-by-side and my Harley. I will be using this in my cars also. I am a preferred customer and enjoy the savings.

Gave it four stars only because of its availability on the road . And would not know about engine wear with out tearing down the motor . haven't had to do that on any of the motorcycles I have owned . I did have main bearing failure on a 4.3 GMC Safari van that I owned from new at 98,700 mi. I did all the oil changes using NAPA WIX filters my self around the 5,000 mile mark using Amsoil . That is the only engine failure I have had in my life of 64 years of vehicle ownership. Now I only use Amsoil in my chain saws and motorcycle. I consider them being more extreme use and worth the added cost.

Great product and price, fast delivery, easy online order, direct from Amsoil.

I didn't ever think I'd be able to afford Amsoil, however, with the price of oil going up all over the place, is not that much different. So now I can finally afford Amsoil, yeah me.
