Valvoline Motor Oil, 10W-40, 1 QT Pack of 2 | Full Synthetic | 4-Stroke Motorcycle

Seems to be a good quality oil, I used it in my 2003 yz125 and 2005 yz85. The clutch seemed to act normal and it shifted good.

Used for a z125, good quality synthetic oil at a much better price than parts store. Good compatibility with motors.

Great oil got my bike shifting super smooth.

Works great in 2022 XR650L. Shifts smoother and better clutch feel than Honda GN4 oil. Used honda oil for break in but I'll be using this valvoline from here on out.

Works great at a good price. What can I say, it’s Valvoline

Tried different oils over the years, this one makes my Vulcan's engine sound tight as Brand New 0 miles, so smooth.... Highly recommended. I wish valvoline had a motorcycle version of the "restore and protect" oil.

Performance: Provides excellent thermal stability and engine cleanliness under high-heat conditions. Perfect for keeping small engines and wet-clutch systems running smoothly. ​Pros: Smooth shifting, reliable formulation, resists breakdown under heavy load. ​Cons: Can be a bit pricier than conventional oils, but worth it for the long-term protection.

This is the only brand of oil I will use in my motorcycles. I have never had a motor issue, and this is a good value.
