Briggs & Stratton 100107 2-Cycle Low Smoke Engine Oil, 50:1 mix, 3.2 oz Bottle

What It Is

This is a pre-measured 3.2 oz bottle of Briggs & Stratton 2-cycle low-smoke engine oil, designed for 50:1 fuel mix. It’s intended for small air-cooled two-stroke engines in handheld lawn equipment like trimmers, blowers, chainsaws, and edgers.

Fitment & Compatibility

Before buying, confirm your engine requires a 50:1 fuel-to-oil ratio (not 40:1 or 32:1). This oil is for Briggs & Stratton 2-cycle engines only—do not use in 4-cycle mowers or any engine labeled “4-cycle.” Check your equipment’s owner manual or the engine label for the exact mix ratio. This bottle treats 1 gallon of gasoline (128 oz ÷ 3.2 oz = 40:1? No—50:1 means 2.6 oz per gallon, so this 3.2 oz bottle treats slightly more than 1 gallon; use the whole bottle for 1.25 gallons). It’s OEM-specified, not a universal aftermarket oil, so it’s safe for all B&S 2-cycle handheld tools.

Key Things to Know

• Low smoke formula – Reduces visible exhaust and smoke compared to standard 2-cycle oils; helps with cleaner operation and less mess.
• Pre-measured bottle – No measuring needed; just pour the entire bottle into 1.25 gallons of unleaded gasoline and shake. Do not mix with less than 1 gallon—ratio will be off.
• Easy installation – No tools required. Simply add to gas can before filling with fuel. Avoid mixing directly in the equipment tank.
• Common gotcha – Using this in a 4-cycle engine (like a push mower) will cause severe damage. Always double-check your engine type.

Should You Buy It

Buy this if you own a Briggs & Stratton 2-cycle handheld tool (trimmer, blower, chainsaw) and want a hassle-free, pre-measured low-smoke oil that meets OEM specs. It’s ideal for occasional users who don’t want to measure or risk mix errors. Skip it if you need a different ratio (e.g., 40:1) or have a 4-cycle engine.
