Suzuki ECSTAR V7000 10W-40 Marine 4-Stroke Engine Oil, 2 Gal (990C0-01E30-GLNx2
The Suzuki ECSTAR V7000 10W-40 is factory-branded oil, meaning it's formulated to Suzuki's own specifications — a straightforward match for the Raider R150's air-cooled 150cc engine, which runs well on 10W-40 viscosity across typical riding temperatures. The 2-gallon jug gives you multiple oil changes from one purchase, reducing per-change cost. Honest caveat: this is marketed as marine oil, so confirm it carries JASO MA2 certification before using it in a wet-clutch engine.
