Briggs & Stratton 6-Pack 2-Cycle Oil - 3.2 Oz. 100107

What It Is

This is a 6-pack of pre-measured 3.2 oz bottles of Briggs & Stratton 2-cycle oil (part #100107), designed for mixing with gasoline in small engines that require a 50:1 fuel-to-oil ratio—typically handheld lawn equipment like trimmers, blowers, edgers, and chainsaws.

Fitment & Compatibility

Before buying, confirm your engine requires a 50:1 mix (not 40:1 or 32:1). This oil is for Briggs & Stratton 2-cycle engines only; it will not work in 4-cycle engines. Check your equipment’s manual or the fuel cap for the correct ratio. This is an OEM product, so it’s a direct fit for any B&S 2-cycle engine. For non-Briggs brands (e.g., Echo, Husqvarna, Stihl), verify they accept 50:1 mix—some require their own branded oil for warranty compliance. Measure your fuel tank size: each 3.2 oz bottle treats 1 gallon of gas, so a 6-pack covers 6 gallons.

Key Things to Know

• Quality: Meets Briggs & Stratton’s TC-W3 and JASO FD standards, providing good protection against wear and carbon buildup. Not synthetic, but fine for most homeowner use.
• Installation: No tools needed—just pour one bottle into 1 gallon of unleaded gas (87 octane or higher) and shake. Easy, but don’t mix more than you’ll use within 30 days to avoid fuel degradation.
• Common gotcha: Do not use in 4-cycle engines (like walk-behind mowers)—it will cause smoke and damage. Also, avoid ethanol-blended gas above E10; ethanol can attract moisture and harm the oil mix.
• Cost: At ~$3.15 per bottle, it’s slightly pricier than generic 50:1 oils, but convenient and backed by OEM specs.

Should You Buy It

Buy this if you own Briggs & Stratton 2-cycle handheld equipment and want a hassle-free, pre-measured oil that’s guaranteed to meet warranty requirements. It’s a solid choice for homeowners who mix small batches and prefer OEM quality over generic alternatives. Skip it if you have non-Briggs engines needing a different ratio or if you’re mixing large volumes (buy a quart bottle instead).
