Lucas Oil 10474 SAE 5W-30 Motor Oil - 1 Quart

What It Is

Lucas Oil 10474 is a 1-quart bottle of SAE 5W-30 synthetic-blend motor oil designed for small engines in lawn mowers, tractors, zero-turn mowers, and other outdoor power equipment that require a low-viscosity, all-season lubricant.

Fitment & Compatibility

• Engine type: Works in 4-cycle (four-stroke) engines only. Not for 2-cycle or mixed-fuel engines.
• Viscosity requirement: Confirm your engine calls for SAE 5W-30 (common in newer Briggs & Stratton, Kohler, Kawasaki, and Honda engines). Check your owner’s manual or oil fill cap for the recommended weight.
• Capacity: 1 quart (32 oz) is enough for most push mowers (typically 15–20 oz) or small tractors (up to 48 oz). For larger engines, you may need multiple bottles.
• API service classification: Meets or exceeds SJ through SN service categories. If your engine requires a specific certification (e.g., Briggs & Stratton 10W-30), double-check compatibility—this oil is not a direct replacement for all OEM-specified viscosities.

Key Things to Know

• Synthetic blend: Provides better cold-start protection and high-temperature stability than conventional oil, but costs more per quart.
• Installation difficulty: Easy—just drain old oil (warm engine), replace drain plug, and refill to the correct level. No special tools needed.
• Gotcha – Overfilling: Adding the full quart to a small engine that holds 18 oz will cause foaming, leaks, or engine damage. Always measure and check dipstick.
• Storage: Unused oil has a long shelf life if sealed; store in a cool, dry place away from direct sunlight.

Should You Buy It

Buy this if your small engine specifies 5W-30 and you want a reliable synthetic-blend oil from a trusted brand for year-round use. It’s a solid choice for most modern push mowers and tractors, but skip it if your engine requires a different viscosity (e.g., 10W-30 or SAE 30) or if you’re on a tight budget—conventional oil works fine for seasonal use.
