Best Engine Oil for Triumph Trident 660

#1

Liqui Moly 4T 10w40 Basic Street 4-Liter

Liqui Moly's 4T 10W-40 is a solid match for the Triumph Trident 660 because its viscosity sits squarely within Triumph's recommended 10W-40 range for the parallel-triple engine, keeping oil pressure stable across both cold starts and highway cruising. The 4-liter jug covers an oil change with a little left over, which is practical. Liqui Moly's reputation for wet-clutch compatibility is well-earned here. Caveat: this is a mineral-based oil, so riders doing hard track days or riding in extreme heat may want a full-synthetic instead.
