Mag 1 60138 Universal 2-Cycle Oil - 8 Ounce

What It Is

Mag 1 60138 is an 8-ounce bottle of pre-mixed 2-cycle oil designed for small engines that require a 50:1 fuel-to-oil ratio. It’s intended for use in handheld lawn equipment like string trimmers, leaf blowers, hedge trimmers, and chainsaws, not for lawn mowers with 4-cycle engines or separate oil reservoirs.

Fitment & Compatibility

Before buying, verify two things:

1. Engine type: This oil is strictly for 2-cycle (2-stroke) engines. Do not use in any 4-cycle mower, tractor, or zero-turn—those require separate engine oil (e.g., SAE 30, 10W-30).

2. Fuel ratio: The bottle is pre-mixed at 50:1. Check your equipment’s manual. If it requires 40:1 or 32:1, this oil will be too thin and could cause engine damage.

Brand/model fit: Universal for any 2-cycle small engine brand (Husqvarna, Echo, Stihl, Ryobi, etc.) that uses 50:1 mix. No specific deck size or OEM part number needed.

Measurements: 8 ounces treats 1 gallon of gasoline at 50:1. If you need more or less, adjust accordingly.

Key Things to Know

• Low rating (2.9/5) is a red flag. Most complaints cite poor lubrication, excessive smoke, or carbon buildup. Compare to TC-W3 or JASO FD-rated oils from established brands (e.g., Stihl, Echo, Husqvarna).

• Installation is trivial: Pour entire 8 oz bottle into 1 gallon of fresh, unleaded gas. Shake well. No tools required.

• Common gotcha: Using old or ethanol-blended gas with this oil can cause separation or varnish. Always use fresh fuel and mix within 30 days.

• Pre-mixed vs. separate: This is a pre-mix bottle—do not add extra oil. If your engine requires a different ratio, this product won’t work.

Should You Buy It

Only buy this if you need a cheap, single-use 8 oz bottle for a 50:1 2-cycle engine and you’re okay with mediocre performance and potential smoke. For slightly more, a higher-rated oil from a dedicated small-engine brand will provide better engine protection and less hassle. Avoid if you value long engine life or run demanding equipment.
