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.

This oil is a replacement for the Mobil1 10W40 mc oil - this is only anecdotal but there is a lower sounding engine noticed right from the initial start with the Amsoil - just goes to show the advantage of a 100% oil over a fully synthetic oil - specs always beat advertising gimmicks. Go Amsoil

I use Amsoil in my 2012 Honda Goldwing. Never smells burnt when I change it out, goldwings have the wet clutch, tranny and the engine all running from the same oil sump. No issues with clutch or shifting, engine always runs cool.

Been using the Metric oil for both my 1200 GS and my 1250. Great stuff will never use anything else! Expensive bikes use expensive oil but you get what pay for. I trust Amsoil to keep my engine running smooth.

Works great stays clean longer transmission is quiet.

used for maintaining a friends bike

Was exactly what i needed, quick shipping and even got a sticker. Tysm

Awesome product for the bike

I've used this for years, decades in my bikes. I've never had an issue. I will continue with it.

My dealing with AMSOIL has been GREATE. The product has always been delivered in a timely manner. The product is of the highest quality. Thanks AMSOIL Alan

Do not be a fool! You can try them all , but once you try this one you will never buy another brand other than Amsoil.

I have been using this in all the motorcycles I have owned and have never been disappointed. Great product.
