Valvoline 4-Stroke Motorcycle Full Synthetic 10W-40 Motor Oil 1 Quart
Valvoline's full synthetic 10W-40 matches the viscosity Triumph specifies for the Tiger 900's inline triple, making it a straightforward, compatible choice for routine oil changes. The fully synthetic formula handles the engine's relatively high operating temperatures well, and the 1-quart size is useful for top-ups between changes. Caveat: you'll need three to four quarts for a full drain-and-fill, so budget accordingly before ordering.
