Greyhound 15W-40 CK-4 Engine Oil 5L
Greyhound G-Premium 15W-40 CK-4 is a premium heavy-duty diesel engine oil engineered for high performance under severe operating conditions. Specifically, this 5L grade meets the requirements of modern low-emission engines while remaining fully backward-compatible with older diesel technologies.
Because it provides stable viscosity and strong thermal resistance, this oil delivers long-drain performance for fleets operating under high temperature, heavy load, stop-start cycles or extended idling. Moreover, it suits EGR, SCR and DPF-equipped engines where CK-4 is recommended.
