HONDA MOTOR OIL 10W30 QT (PACK OF 2)
Honda's own 10W-30 motor oil is a straightforward match for the Supra X 125, which calls for exactly that viscosity grade in its owner's manual. Using the manufacturer's branded oil removes any guesswork about additive compatibility with the wet clutch system these small Honda engines rely on. The two-quart pack covers roughly two oil changes, keeping a spare on hand. Caveat: verify your local Supra X 125 variant's exact capacity, as some regional builds specify slightly different intervals.
