Briggs and Stratton 2 Pack of Genuine OEM Replacement 2 Cycle Oil - 100107-2PK

What It Is

This is a 2-pack of genuine Briggs & Stratton 2-cycle oil (part 100107-2PK), pre-mixed for use in small engines that require a 50:1 fuel-to-oil ratio. It’s designed for handheld outdoor power equipment like string trimmers, leaf blowers, hedge trimmers, and small chainsaws.

Fitment & Compatibility

Before buying, confirm your engine is a 2-cycle (not 4-cycle) model. This oil is for engines requiring a 50:1 mix—do not use in engines calling for 40:1 or 32:1 ratios unless you adjust the mix. Works with most Briggs & Stratton handheld equipment, but also fits many other brands (e.g., Troy-Bilt, Murray, Snapper) that use a 50:1 spec. Check your owner’s manual or look for “50:1” on the fuel cap or engine label. Each bottle is 2.6 oz, designed to mix with 1 gallon of unleaded gasoline.

Key Things to Know

• Genuine OEM: This is original Briggs & Stratton oil, not an aftermarket substitute—ensures proper lubrication and protects warranty on Briggs engines.
• No mixing required: Pre-measured bottles simplify the process—just pour one bottle into 1 gallon of gas and shake.
• Storage tip: Once mixed, use within 30 days to maintain fuel stability; add fuel stabilizer if storing longer.
• Common gotcha: Do not use in 4-cycle engines (like lawn mowers) or in 2-cycle engines requiring a different ratio—mixing wrong can cause engine damage.

Should You Buy It

Buy this if you own a 2-cycle handheld tool that needs a 50:1 mix and want a hassle-free, OEM-recommended oil that protects your engine and simplifies fueling. It’s a solid value for the price and a safe choice for most home-use small equipment.
