Fits Stens Synthetic Blend 2 Cycle Engine Oil 2.6 Oz Makes 50:1 Ratio Low Smoke

What It Is

This is a 2.6 oz bottle of Stens synthetic blend 2-cycle engine oil, pre-measured to mix with 1 gallon of unleaded gasoline for a 50:1 fuel-to-oil ratio. It’s designed for air-cooled, small-displacement 2-cycle engines commonly found in handheld lawn equipment like trimmers, leaf blowers, chainsaws, and hedge trimmers—not for riding mowers or 4-cycle engines.

Fitment & Compatibility

Before buying, confirm your equipment requires a 50:1 mix (most modern 2-cycle tools do). Check the oil fill cap or owner’s manual for the recommended ratio—older units may need 40:1 or 32:1, which this bottle won’t match. This oil fits any 2-cycle engine brand (Stihl, Husqvarna, Echo, Ryobi, etc.) as long as you’re mixing 2.6 oz per gallon. It’s an aftermarket replacement for OEM oils like Stihl HP Ultra or Echo Power Blend. No deck size or hardware measurements apply—just verify your engine is 2-cycle and uses 50:1.

Key Things to Know

• Quality: Stens is a well-known aftermarket brand in the outdoor power equipment industry. This synthetic blend offers good lubrication and reduced smoke compared to cheap mineral oils, but it’s not a full synthetic—expect slightly more deposit buildup over time.
• Installation: Zero difficulty. Pour the entire 2.6 oz bottle into 1 gallon of fresh, unleaded gasoline (87 octane or higher, no ethanol preferred), shake well, and fill your tool’s fuel tank. No measuring needed.
• Common gotcha: Don’t use this in 4-cycle engines (push mowers, tractors) or in 2-cycle engines requiring a different ratio. Also, mixing with ethanol-blended gas can attract moisture and degrade fuel stability—use within 30 days.
• Low smoke claim: Works as advertised, but “low smoke” is relative. Expect less visible exhaust than conventional 2-cycle oils, but not zero smoke.

Should You Buy It

This is a solid choice if you need a convenient, no-measure 50:1 mix for occasional use on multiple 2-cycle tools and want a reputable aftermarket brand at a lower price than OEM oils. It’s not for high-performance engines (like pro-grade chainsaws used daily) or for 40:1 equipment—stick with full synthetic or OEM for those. For most homeowners, it’s a reliable, budget-friendly option.
