I use this oil in my 06 Yamaha Warrior 1700. The heat the engine puts off is intense on hot days. Since using this oil there is a noticeable difference in the heat the engine puts off. I had an issue with Yamalube Gold foaming. The Amsoil Metric 10W40 does not foam in my bike. Excellent oil.

I am satisfied with the products you sell and the discount for being a member is a plus but I don't seem to get the extra goodies to do with the promo code . One time it was shop rags and the last time it was the magnetic ash tray looking bolt tray . It's not a big deal but don't promise me these trinkets if you don't send them. Just so the oils remain as great as they are . Thanks Terry

Only reliable 10w 30 moto oil I could find and it shipped pretty fast

First time trying amesoil, loved it this product did all it claims unlike the others. 10 30 metric motorcycle full synthetic calmed the slight valve noise and stopped the clutch vibration I was getting from inferior oils. Will always use amesoil in my bikes from now on

I want the best oil for my Kawasaki zrx 1200R

This stuff is the real deal I use it in my Suv and Spyder

Other than oil consumption, in a motorcycle, for me, the next milestone is how smoothly the transmission shifts. I just changed the oil. I rode for a period of 2 hours after the oil change. The transmission shifts very smoothly for which I am very pleased.

My kawasaki ninja 1000abs loves this oil. Only the best out there now. Others will say they are, but we all know Amsoil track records speak for themselves

The order arrived before I expected, the Amsoil website recommended 4 quarts for the job, but I needed 5.5 quarts. Make sure you know your vehicles capacity before ordering. I have been using Amsoil on and off since the mid 1990s and have had great success both in engines and transmissions. A great engine life extending product.

Have used this in both my GS1200R and 1250 works great it could tell the difference in the shifting. Have 42000 miles on my 1200 this is the only oil I use.

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.
