Pack of 5 Kawasaki 99969-6296 Genuine OEM K-Tech SAE 10W-40 4-Cycle Engine Oil
Kawasaki's own K-Tech 10W-40 is a straightforward match for the Z300 because it meets the viscosity spec Kawasaki specifies for that parallel-twin engine across typical riding temperatures. Buying it in a five-pack keeps oil changes covered for a couple of years without hunting for compatible alternatives. It's genuinely OEM-grade, so there's no guesswork about compatibility. The honest caveat: you're paying a premium over comparable third-party 10W-40 motorcycle oils that would perform equally well.
