STIHL 0781 313 8002 2.6 Ounce High Performance Ultra 2 Cycle Engine Oil, 6 Pack

What It Is

This is STIHL’s pre-mixed, high-performance 2-cycle engine oil designed specifically for STIHL handheld outdoor power equipment—chainsaws, trimmers, blowers, and hedge trimmers. The 2.6-ounce bottles are single-use, pre-measured to mix with 1 gallon of unleaded gasoline at a 50:1 ratio.

Fitment & Compatibility

• Intended use: STIHL gasoline-powered 2-cycle engines only (not for 4-cycle or electric equipment).
• Ratio: Exactly 2.6 oz per 1 gallon of gas (50:1). Do not use with different ratios unless specified by your engine manual.
• Fuel type: Mix with minimum 89-octane unleaded gasoline (up to 10% ethanol OK, but avoid higher ethanol blends).
• Not universal: While it works in any 2-cycle engine at 50:1, it is optimized for STIHL engines. For non-STIHL brands, verify your engine’s recommended oil ratio first.
• Shelf life: Unopened bottles last 5+ years if stored indoors; once mixed, use fuel within 30 days to prevent separation.

Key Things to Know

• Quality: STIHL’s Ultra formula exceeds API TC and JASO FD standards—reduces carbon buildup and extends engine life compared to generic oils.
• Installation difficulty: Trivial—just pour entire bottle into 1 gallon of gas, shake, and fill. No measuring needed.
• Common gotcha: These are 2.6 oz bottles for 1 gallon of gas. If your tank is smaller (e.g., 0.8 gal), do not use a full bottle—use a measuring cup to avoid over-oiling.
• Price note: At ~$4 per bottle, this is premium oil. Generic 2-cycle oil is cheaper but may not protect as well in high-RPM STIHL engines.

Should You Buy It

Buy this if you own any STIHL 2-cycle equipment and want a hassle-free, pre-measured oil that guarantees correct mixing and top-tier engine protection. It’s ideal for occasional users who don’t want to measure oil themselves, and for anyone who values long engine life over saving a few dollars per gallon.
