Kirkland Signature Full Synthetic 0W-20 Motor Oil is a premium 100% synthetic engine oil designed for gasoline engines requiring SAE 0W-20 viscosity grade. This 2-pack includes two 5-quart (4.73L) bottles providing 10 quarts total capacity. The advanced synthetic formulation provides superior wear protection for extended engine life and maximizes fuel economy compared to conventional oils.

This oil meets or exceeds API Service SP, SN PLUS, SN, and SL specifications, as well as ILSAC GF-6A, GF-5, and GF-4 standards. It is approved for use in all GM gasoline engines requiring dexos1 Gen 3 0W-20 specification. The formulation helps prevent Low-Speed Pre-Ignition (LSPI) commonly seen in modern turbocharged direct-injection gasoline engines. Each container features a clear viewing strip to monitor remaining oil level.

Suitable for gasoline, E85 flex-fuel, and gasoline-electric hybrid vehicles requiring 0W-20 motor oil. The synthetic base provides excellent cold weather starting protection and maintains optimal viscosity across a wide temperature range. Third-party oil analysis testing has shown wear metal levels below universal averages and high Total Base Number (TBN) retention after extended drain intervals, confirming exceptional lubrication performance comparable to premium synthetic brands.
