Chevron Supreme SAE 5W-30 Supreme Motor Oil - 1 Quart Bottle (83723)

What It Is

Chevron Supreme SAE 5W-30 is a conventional motor oil designed for small engines in lawn mowers, tractors, and other power equipment. It provides reliable lubrication and protection for 4-stroke engines operating in moderate to warm climates.

Fitment & Compatibility

• Engine type: For 4-stroke (4-cycle) engines only—not for 2-stroke or mixed-fuel engines.
• Viscosity: SAE 5W-30 is best for air-cooled engines in temperatures above 0°F (-18°C). Check your owner’s manual for the recommended oil weight (many small engines specify SAE 30 or 10W-30; 5W-30 is a common alternative for easier cold starts).
• Capacity: One quart (32 oz) is typically enough for most walk-behind mowers (18–20 oz fill) or a partial fill for larger tractors (check your dipstick or manual for exact capacity).
• Brand/OEM: Not OEM-specific; works with any brand (Honda, Briggs & Stratton, Kohler, Kawasaki, etc.) that accepts 5W-30 or 10W-30. Avoid if your engine requires synthetic-only oil (e.g., some high-performance zero-turn models).
• Measurements: No special measurements needed—just verify oil type and capacity.

Key Things to Know

• Quality: Conventional oil, not synthetic. Good for routine changes but not for extreme temperatures or heavy-duty use. Meets API SN/ILSAC GF-5 standards.
• Installation: Easy—drain old oil, replace filter (if equipped), and fill to dipstick mark. No special tools required.
• Common gotchas: Don’t overfill—use the dipstick, not the entire quart if your engine takes less. Avoid mixing with synthetic oils unless your manual allows it. This oil is not for snow blowers or equipment stored below 0°F (use synthetic 5W-30 or 0W-30 for extreme cold).
• Shelf life: Unopened, lasts 3–5 years. Once opened, use within 1 year and seal tightly to prevent moisture.

Should You Buy It

Buy this if you need a budget-friendly conventional 5W-30 for routine oil changes in a walk-behind mower or small tractor used in moderate climates. Skip it if your engine requires synthetic oil, if you operate in extreme cold, or if you prefer a multi-grade like 10W-30 for higher heat tolerance. For the price, it’s a solid choice for basic maintenance.
