Briggs & Stratton 2-Cycle Easy Mix Motor Oil - 16 Oz. 100036 (Pack of 2)

What It Is

This is a pre-mixed 2-cycle engine oil designed for Briggs & Stratton handheld outdoor power equipment. It eliminates the need to mix gasoline and oil separately, ensuring the correct 50:1 fuel-to-oil ratio for engines like those in trimmers, blowers, and chainsaws.

Fitment & Compatibility

• Engine types: Only for 2-cycle (2-stroke) air-cooled engines. Not for 4-cycle mowers or any engine requiring separate oil fill.
• OEM vs aftermarket: This is genuine Briggs & Stratton oil (part 100036), fully compatible with their 2-cycle engines. Works in most major brands using 50:1 mix (e.g., Echo, Husqvarna, Ryobi, Stihl) but check your manual for exact ratio.
• What to verify: Confirm your equipment requires a 50:1 ratio—some older models need 32:1 or 40:1. Also check that the fuel tank is clean and compatible with pre-mix (no ethanol issues).
• Measurement: Each 16 oz bottle treats 1 gallon of gasoline when using the full bottle. Pack of 2 treats 2 gallons total. No measuring needed.

Key Things to Know

• Installation difficulty: Trivial—just pour the entire bottle into a gallon of fresh gasoline, shake, and fill the tank. No mixing tool required.
• Quality: Formulated for reduced smoke and deposits, and it meets JASO FD and ISO-L-EGD standards for high-performance 2-cycle engines.
• Common gotcha: Do not use in 4-cycle engines or any equipment requiring separate oil. Also, don’t mix with other oils or ratios—stick to 50:1 only.
• Shelf life: Pre-mixed fuel should be used within 30 days; store unopened oil in a cool, dry place for up to 3 years.

Should You Buy It

Buy this if you own a 2-cycle trimmer, blower, or chainsaw and want a no-mess, no-measure solution that guarantees the correct ratio and protects your engine. It’s ideal for occasional users who don’t want to deal with separate mixing bottles or worry about mistakes. If you have a 4-cycle mower or need a different ratio (e.g., 32:1), skip this.
