Kirkland Signature Full Synthetic SAE 5W-20 Motor Oil comes in a convenient 6-pack of 1-quart bottles, offering a total of 6 quarts of premium engine protection. Manufactured in the United States, this full synthetic formula is designed specifically for gasoline engines and provides superior lubrication across a broad range of operating temperatures.

The 5W-20 viscosity grade ensures excellent cold-start protection while maintaining optimal oil film thickness at high operating temperatures. Full synthetic formulation delivers advanced wear protection to extend engine life, controls thermal breakdown caused by excessive heat, and helps keep engines cleaner by resisting sludge and deposit buildup. Kirkland Signature motor oils are produced by Warren Distribution, the same manufacturer behind other leading synthetic oil brands, and are formulated to meet or exceed API SP and ILSAC GF-6A standards, making them suitable for modern gasoline engines including direct-injection and turbocharged applications.

Each bottle is a 1-quart (32 fl oz) container, and the 6-pack format offers excellent value for routine oil changes or keeping a supply on hand. Compatible with a wide range of domestic and import vehicles that specify 5W-20 motor oil.
