Seachoice 2-Cycle Engine, Oil to Gas Measuring Container, 32 Oz., Wide Mouth Bottle

What It Is

This is a 32-ounce wide-mouth plastic container with dual graduated scales for mixing 2-cycle engine oil with gasoline. It’s designed for any small engine that requires a pre-mixed fuel-oil ratio, such as handheld trimmers, chainsaws, leaf blowers, and some older 2-cycle lawn mowers.

Fitment & Compatibility

• Not for 4-cycle engines – Only use with 2-cycle (2-stroke) engines that require oil mixed directly into the gas tank.
• Check your engine’s oil-to-gas ratio – The container has markings for 16:1, 24:1, 32:1, 40:1, and 50:1 mixes. Verify your engine’s requirement in the owner’s manual (common ratios: 40:1 for most modern trimmers, 50:1 for newer Stihl/Echo models, 32:1 for older mowers).
• No brand or model restrictions – Works with any gasoline-powered 2-cycle engine. No deck size or OEM compatibility concerns.
• Measurements – 32 oz (0.95 L) total capacity. The wide mouth (about 2.5” diameter) fits most gas can spouts and funnels.

Key Things to Know

• Accuracy – Graduations are printed, not embossed, so they may wear off over time. Use a permanent marker to re-mark your common ratio if needed.
• No installation required – Just fill with gas, add oil to the correct line, shake, and pour. No tools or mechanical skill needed.
• Common gotcha – Do not use this container for long-term storage of mixed fuel. The plastic is not fuel-proof for extended periods; use a dedicated fuel can instead.
• Wide mouth helps – Easier to pour oil without spills compared to narrow-neck bottles, but still take care when adding oil—it’s easy to overfill.

Should You Buy It

If you own any 2-cycle engine equipment and want a simple, low-cost way to mix fuel accurately without guesswork, this is a solid buy. It’s not a precision lab tool, but for the price and 4.7-star rating from over 2,300 users, it reliably gets the job done for homeowners and weekend users. Skip it if you need a long-term storage container or a more durable embossed scale.
