I've been using using the 10W-40 Metric product in a CBR1000RR for most of a race season now with filter changes and a top up between weekends. Where most folks will change after every race weekend, I only had to do a full change after three, and I probably could have gone longer. My engine runs cooler and shifts smoother with this too. Can't recommend it highly enough.

I started using it in my yfz450r after conventional oil was not holding its viscosity after 5 hrs - the Amsoil still looks new after 5 hrs! I use it in my sons xr- 80 and my youngest sons xr50 - it honestly brought the tired little 50 back to life - easier starts- smoother shifts (almost seemless) and the engine is much quieter -after that i swear by Amsoil and will use nothing else in my machines!

I've used amsoil for as long as I can remember, once you use it for the first time, you just can't stop using it. It's that simple.

I’ve been using Amsoil in every vehicle I own, including my Harley and Triumph motorcycles. Even all my 4 cycle power equipment! I’ve never had any issues with any engine. My Diesel powered truck has over 300k miles and still runs like new! Knowing I have a high quality oil in my vehicles and power equipment gives me peace of mind!

Great product.

I have used Amsoil in the last three motorcycles that I owned including the one I now have. I've always been very happy with the quality and service I get from your product. Ordering online has made it even better for me now because I'm not looking for local suppliers. keep up the good work.

It's the best oil

Been using Amsoil Vtwin oil for years in my Victory XC tour, loved it! Now I have a goldwing I am using this oil, I am sure it will be just as good. Just put it in my last oil change.

I have been using Amsoil for quite some time and I love the oil it works great keeps your engine cooler and does what I need to do.

I've used the metric 10w- 40 on both of my GS's my 2018 Rallye has 42000 miles on it long days 500 plus miles never worried about the engine. Now in 2022 after the break in on my 2022 GS 40 year Amsoil went in and will take care of my new bike for another 40K plus. It's just good stuff..

moteur plus doux , moin bruillant

I use this oil in both my motorcycle and my wife's motorcycle. I've done 30k miles on my bike over the three years here, and I've never had a problem with my oil. When you're on two wheels, why risk using junk oil that will leave you stranded somewhere?

Run a Goldwing service and maintenance shop, Have used 10w40 synthetic motorcycle oil for 20 years , many bike upwards of 300 K on them, no oil related failures at all, great wet clutch life also with at at least 100 wing s ,,,, 75- 2015.

This oil is great, I am running it in my Yamaha CP2 engine. It shifts crisp with no clutch slippage and runs cooler than with the Yamalube Oil.

Just the best oil. Period. I try to use in all my vehicles. Worth the price.

I took a solo trip from MD to Alaska and back and needed fresh oil for my return home. Amsoil had oil for sale at a reasonable price. Although I have not used Amsoil, I have friends that use it and highly recommend using this oil.

I have a 2006 Honda goldwing and I wouldn't use anything else.

Been running Amsoil in pretty much everything since I first became a dealer in 1975 or 1976... 10W-40 Synthetic Metric Motorcycle Oil in both my 2003 Honda CB600 (now gone) and my current Honda VFR800 Interceptor. Great feeling to know you are safe even if you don't get to your oil change when it is due. Never had a problem. Highly recommended!

Run it in my Can-Am Spyders for 10 never a problem great oil

I run this metric motorcycle oil in my 2006 Yamaha Warrior. The engine is a 1700 and it puts off a lot of heat. I’ve noticed a difference of less heat on hot days. The engine sounds quieter and is really smooth. I will be using this oil each season in this bike.
