Briggs & Stratton 2-Cycle Oil - 8 Oz. 272075

What It Is

This is Briggs & Stratton’s OEM 2-cycle oil (8 oz., part #272075) formulated for air-cooled, 2-cycle engines used in handheld lawn equipment like trimmers, blowers, chainsaws, and edgers. It’s a pre-measured bottle designed for a single fuel mix.

Fitment & Compatibility

• Engine types: Only for Briggs & Stratton 2-cycle engines (e.g., Quantum, Quattro, Intek, and older models). Does not fit 4-cycle engines.
• Mixing ratio: 50:1 (2.6 oz. per gallon of gasoline) – the 8 oz. bottle treats 3 gallons of fuel. Use regular unleaded gas (87 octane, max 10% ethanol).
• Check your manual: Confirm your specific engine model (stamped on the engine shroud or muffler) requires 2-cycle oil. Some older B&S 2-cycle engines use a 40:1 ratio; this oil works for both, but verify.
• OEM vs. aftermarket: This is OEM B&S oil. Aftermarket options (e.g., Stihl, Echo) are compatible if they meet B&S specification, but this ensures warranty compliance for B&S engines.
• Measurement: Bottle is 8 oz. – no measuring cup needed; pour entire bottle into 3 gallons of gas.

Key Things to Know

• Pre-mix only: Never pour directly into the engine oil tank. Mix with gasoline in a separate container before filling the fuel tank.
• Storage: Unused mixed fuel degrades in 30 days. Use fuel stabilizer if storing longer.
• Installation difficulty: Trivial – just mix and pour. No tools required.
• Common gotcha: Do not use in 4-cycle engines (e.g., push mowers, tractors). It will cause smoke and engine damage.

Should You Buy It

Buy this if you own a B&S 2-cycle handheld tool and want a no-brainer, pre-measured mix that protects your engine and keeps the warranty valid. It’s ideal for occasional users who don’t want to measure oil or risk using the wrong ratio. Skip it if you have a 4-cycle engine or prefer a different brand’s oil (e.g., for non-B&S equipment).
