MAG 1 61652 SAE 5W-30 Synthetic Blend Motor Oil - 1 Quart

What It Is

MAG 1 61652 is a 1-quart bottle of SAE 5W-30 synthetic blend motor oil designed for 4-cycle lawn mower engines, including walk-behind mowers, riding mowers, zero-turn mowers, and small utility tractors. It provides year-round lubrication in moderate to cold temperatures.

Fitment & Compatibility

• Oil type: 4-cycle engines only. Do not use in 2-cycle engines or mix with gas.
• Viscosity: SAE 5W-30 – ideal for engines operating in temperatures from -20°F to 100°F. Check your mower’s manual for recommended viscosity.
• Capacity: 1 quart (32 oz). Most push mowers take 18–20 oz; riding mowers typically need 1.5–2 quarts. Confirm your engine’s oil capacity before buying.
• Brand/model fit: Compatible with most Briggs & Stratton, Kohler, Kawasaki, Honda, and Tecumseh 4-cycle engines. No OEM-specific requirements.
• Measurements: Standard quart bottle with a long spout for easy pouring into small fill tubes.

Key Things to Know

• Synthetic blend vs. full synthetic: MAG 1 is a blend, offering better cold-start protection and longer life than conventional oil, but less extreme-temperature performance than full synthetic. Fine for most residential mowers.
• No API rating listed on bottle – but it meets industry standards for small engines. For high-hour commercial use, consider a full synthetic with API SN or higher.
• Installation difficulty: Easy – just drain old oil (warm engine), replace the fill cap, and pour. No special tools needed.
• Common gotcha: Overfilling can cause engine damage. Always check the dipstick after adding, and never exceed the “full” mark.

Should You Buy It

If you have a standard residential 4-cycle mower and want affordable, reliable oil for seasonal use in moderate climates, the MAG 1 5W-30 synthetic blend is a solid choice. It’s not the best for extreme heat or heavy commercial duty, but for most homeowners it offers good value and easy availability.
