Briggs and Stratton 6-Pack 100074 Quart 5W-30 Synthetic Oil

What It Is

This is a 6-pack of Briggs & Stratton 100074 5W-30 synthetic oil, each quart bottle designed specifically for small engines in lawn mowers, tractors, zero-turn mowers, and other outdoor power equipment. It’s formulated for 4-cycle engines that require 5W-30 viscosity, including many Briggs & Stratton, Kohler, Kawasaki, and Honda engines.

Fitment & Compatibility

Before buying, check your engine’s oil viscosity requirement (look for 5W-30 in your owner’s manual or on the oil fill cap). This oil is OEM spec for Briggs & Stratton engines but also works with most other brands that call for 5W-30 synthetic. It is not for 2-cycle engines or engines requiring SAE 30 or 10W-30. Measure your engine’s oil capacity—each quart is 32 oz., so a 6-pack covers engines needing 1–6 quarts (common mower engines take 15–20 oz., so a single quart often does two oil changes). No deck size or model-specific fitment issues; compatibility is purely based on viscosity and engine type.

Key Things to Know

• Quality: Full synthetic, high-temperature stability, and detergent additives reduce sludge and wear. Meets API SM/SL and JASO MA/MA2 standards.
• Installation: Easy DIY—just drain old oil, replace filter (if equipped), and pour. No special tools. One quart is typically enough for most mowers; check your engine’s capacity.
• Common gotcha: This is 5W-30, not SAE 30—using it in an engine that requires straight 30-weight can cause leaks or poor lubrication in high heat. Also, the 6-pack is bulk—if you only need one quart, buy a single bottle instead.
• Storage: Sealed bottles have a long shelf life (5+ years) if kept in a cool, dry place.

Should You Buy It

This is a solid buy if you own multiple small engines (mower, generator, pressure washer) that all take 5W-30 synthetic, or you want to stock up for several oil changes. It’s right for DIYers who value engine protection and convenience, but skip it if you only need a single quart or your engine requires a different viscosity.
