Label says Metric 10W-30 motorcycle oil but works even if there are Standard Bolts

Whether riding aggressively or non aggressively, cruising or in stop-and-go traffic, AMSOIL Synthetic Metric Motorcycle Oil delivers the benefits most important to riders, including premium wear protection; smooth, confident shifts and cool, clean performance. With AMSOIL Synthetic 10W-30 Motorcycle Oil, riders enjoy the confidence and security that comes with providing their bikes maximum protection and performance. It is Warranty Secure™ and will not void your motorcycle’s warranty.

AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL The First in Synthetics® to do the best job protecting your engine.

Reduces Motorcycle Engine Heat, Friction and Wear

In high heat conditions, the Amsoil 10W-30 Motorcycle Oil exceeds the standard for high-temperature film strength to deliver excellent wear protection. It keeps engines running cool by effectively reducing friction and heat, and it contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions. AMSOIL Synthetic Metric Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation-inhibitor additives. It is extremely resistant to volatility and is engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.

No Clutch Slippage – Smooth, Confident Shifts

AMSOIL Metric 10W-30 Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. It is engineered to control heat and prevent slippage and glazing, promoting longer clutch life.

Controls Foam – Bad stuff!! 

High-rpm operation causes some motor oils to foam. When foam bubbles travel between gear teeth or engine components, they collapse, allowing metal surfaces to contact, causing wear. AMSOIL MCT 10W-30 motorcycle oil contains advanced anti-foam additives that help prevent foam, allowing riders to confidently push their bikes to the limit. Also note: This is why we stress NOT to put these aftermarket oil additives in your oil. They often cause good oils to start foaming. Your bike isn’t a lab experement!

  • Smooth, confident shifts
  • Cool, clean performance


An AMSOIL Bonus – Delivers Superior Rust and Corrosion protection

Rust protection to this degree is an AMSOIL exclusive! Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage, such as uncontrolled wear, compression loss and blow-by. Good rust protection, however, comes by design and is not natural to motor oils. In fact some say it’s impossible to achieve due to balances needed in the formulation. Unlike many motorcycle oils, this here AMSOIL  10W-30 Motorcycle Oil contains special anti-rust agents that deliver superior rust protection. With its high 11.1 total base number (TBN), AMSOIL Synthetic Metric Motorcycle Oil provides greater protection from acid corrosion and helps maintain internal engine cleanliness.


AMSOIL 10W-30 Synthetic Metric Motorcycle Oil is engineered for motorcycles that require 10W-30 motorcycle oil, including those made by Honda, Yamaha, Kawasaki and Suzuki.* Recommended for transmissions requiring an API GL-1 fluid. Not recommended where an API GL-4 or GL-5 gear oil is required.

Side note: – If you ever see the choice of 10W-40 and 10W-30 both suggested – choose the 10W-30 first. Go with the lowest viscosity you can get away with until you see oil consumption. When it comes to motorcycles the difference betwixt a 30 and 40 weight is noticeable horsepower to the wheels.  This suggestion is for those who see both weights mentioned though. Newer bikes are all going to lighter weights.


Recommended for use up to twice the motorcycle manufacturer-recommended change interval (miles/hours) or one year, whichever comes first, in engines and transmissions. When using an oil filter other than AMSOIL Ea® Motorcycle Oil Filter, change the filter at standard intervals. Racing or modified engines are excluded from extended drain interval recommendations; oil changes are at the owner’s discretion.

First time Ever Used

By  FRANK,  a  Verified Buyer  from  NJ  on  January 01, 2022

I just picked this bike up a Kawasaki concourse 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.
Difficult to find on the road like all motorcycle specific

By  CHUCK,  a  Verified Buyer  from  Daytona Fl.  on  December 27, 2021

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.
Hint: Motorcycle shops – if you stocked AMSOIL you could drop all the others as there would be no reason for them!
I’m just glad I could afford it.

By  WILLIAM,  a  Verified Buyer  from  Arizona  on  November 29, 2021

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.
The only one

By  DOUG,  a  Verified Buyer  from  Pismo Beach CA  on  October 19, 2021

Over 100K on the 2007 1250 Bandit, I believe from the use of Metric 10W-40. I’ve used all the available synthetics for motorcycles on the Bandit but the only oil that’ll let me go as long as I want to between oil changes is this oil. Every other oil that included all the lauded brands had to be changed between 1500 to 2000 miles because of the Bandits shifting becoming “clunky”. The very first change into the Metric made a believer out of me by the obvious fact my shifting never gets hard with this product. I change my oil now at 4000 miles “just because” with nothing telling me to, like a “clunky” shift.
