A 32 oz. clear plastic measuring bottle purpose-built for mixing 2-stroke (2-cycle) engine oil with gasoline at the correct ratio. Graduated markings on the bottle correspond directly to the volume of gas in your fuel can, so you simply read the gas volume, fill the bottle to the matching mark, and pour — no math, no guesswork, no risk of a too-lean or too-rich mix.
Key Features
- Pre-calculated ratio markings for 100:1, 50:1, 40:1, and 24:1 oil-to-gas mixtures
- Dual-scale graduations in gallons and litres for compatibility with any fuel can
- 32 oz. (quart) capacity wide-mouth bottle for easy filling and pouring
- Clear plastic construction for accurate reading of oil level
- Helps prevent fouled spark plugs and engine seizure caused by incorrect oil ratios
Parts Desk Insights
Best use case: An essential tool for anyone running a 2-stroke outboard, personal watercraft, or small engine that requires pre-mixed fuel.

Pair with a compatible 2-stroke oil:
