Lucas Oil 10058 Semi-Synthetic 2-Cycle Motor Oil - 2.6 Ounce (Pack of 24)

What It Is

This is a pre-measured pack of 24 2.6-ounce bottles of Lucas semi-synthetic 2-cycle engine oil, designed for air-cooled, small-displacement engines in handheld lawn equipment like string trimmers, leaf blowers, chainsaws, and hedge trimmers. It’s a fuel-mix oil (not a crankcase oil) for engines requiring a 50:1 gas-to-oil ratio.

Fitment & Compatibility

• Ratio requirement: Only for engines that specify a 50:1 mix (2.6 oz oil per 1 gallon of gasoline). Do not use in engines requiring 40:1, 32:1, or other ratios without adjusting the gas amount accordingly.
• Engine types: Works in most brands (Husqvarna, Stihl, Echo, Ryobi, Craftsman, etc.) that run 2-cycle, air-cooled engines. Not for 4-stroke engines, marine outboards, or water-cooled motors.
• Pre-mix or direct pour: Each 2.6 oz bottle treats 1 gallon of gas. No measuring needed—just empty one bottle into a gallon of fresh unleaded (87 octane or higher, up to 10% ethanol).
• OEM vs aftermarket: Lucas is a respected aftermarket oil; it meets or exceeds OEM performance specs (e.g., JASO FD, ISO-L-EGD, and API TC). It’s a safe substitute for brand-specific oils like Stihl HP Ultra or Echo Power Blend.

Key Things to Know

• Semi-synthetic blend: Offers better protection and less smoke than straight mineral oil, but not as clean-burning as full synthetic. Good for moderate-use equipment (not daily commercial duty).
• No mixing required: Each bottle is pre-measured for 1 gallon—just pour into the gas can, not directly into the equipment tank. Shake the can well before filling.
• Storage: The pack of 24 bottles is economical but only if you’ll use them within 1–2 years. Oil degrades over time; store in a cool, dry place away from direct sun.
• Ethanol compatibility: Lucas includes stabilizers and corrosion inhibitors, helpful if you use ethanol-blended gas, but always use fresh fuel and avoid storing mixed gas longer than 30 days.

Should You Buy It

Yes, if you own multiple 2-cycle tools that all run a 50:1 mix and you want a convenient, no-measure solution without paying premium per-bottle prices. It’s a solid choice for homeowners and weekend warriors who value consistency and simplicity. Skip it if you need a different mix ratio, prefer full synthetic for extreme conditions, or only have one tool—you’d be better off with a single quart bottle.
