Stens Shield 2-Pack 770-130 SAE 10W-30 4-Cycle Engine Oil 18oz Bottles

What It Is

This is a 2-pack of Stens 770-130 SAE 10W-30 4-cycle engine oil, sold in 18 oz bottles. It’s formulated for small engines found in walk-behind mowers, riding mowers, tractors, and other outdoor power equipment that use a separate oil sump (not mixed with fuel).

Fitment & Compatibility

Before buying, confirm your engine requires SAE 10W-30 viscosity—check your owner’s manual or oil fill cap. This oil is suitable for most Briggs & Stratton, Honda, Kawasaki, Kohler, and Tecumseh 4-cycle engines. It replaces OEM oils like Briggs & Stratton 10W-30, Honda 10W-30, or Kawasaki 10W-30. The 18 oz bottle size fits typical mower capacities (15-20 oz), so one bottle often fills a small walk-behind; two bottles cover a larger riding mower (36-48 oz). No special adapters needed—just pour into the oil fill tube.

Key Things to Know

• Quality assurance: Stens is a reputable aftermarket brand; this oil meets or exceeds API service class SJ or higher for small engines.
• Installation difficulty: Trivial—pull dipstick, pour, check level. No tools required.
• Common gotcha: Do not use in 2-cycle engines (requires oil-fuel mix) or in engines that specify a different viscosity (e.g., SAE 30 for hot climates).
• Storage: Bottles are not resealable once opened—use within a season; leftover oil can be stored in a sealed container away from moisture.

Should You Buy It

Buy this if you own one or more 4-cycle mowers or small engines and want a convenient, affordable 2-pack that matches common oil change needs. It’s a solid value for routine maintenance, especially if you have a riding mower that takes more than a single 18 oz bottle. Skip it if your engine requires a different viscosity (like SAE 30) or if you prefer synthetic blends.
