Spectro Golden Motor Guard Semi Synthetic 10W40
This one’s for the riders who redline on Sunday and commute on Monday. Spectro Golden Motor Guard 10W-40 is your engine’s semi-synthetic shield—tough enough for high-heat hooliganism, smooth enough for stop-and-go reality.
Perfect for V-twins, street machines, and powersport beasts that like a little more cushion in their oil game. High shear stability, strong detergent action, and a golden glow that says, “Yeah, I care about my engine.”
One quart of do-it-all durability.
From gridlock to green flag—this oil shows up.
