STIHL 0781 319 8010 12.8 Ounce High Performance 2 Cycle Engine Oil, 6 Pack

What It Is

This is a 6-pack of STIHL’s proprietary 12.8-ounce bottles of high-performance 2-cycle engine oil, pre-mixed at 50:1 ratio. It’s designed specifically for STIHL handheld equipment (chainsaws, trimmers, blowers, hedge trimmers) and any other 2-cycle engine that requires a high-quality synthetic-blend oil.

Fitment & Compatibility

• Brand/Model: Works with any STIHL 2-cycle engine (e.g., MS chainsaws, FS trimmers, BG blowers). Also compatible with other brands that specify 50:1 mix (e.g., Echo, Husqvarna, Ryobi) but check your owner’s manual first.
• Fuel Ratio: Pre-mixed at 50:1 (2.6 oz per gallon of gas). Do not use in 4-cycle engines or any engine requiring a different ratio (e.g., 40:1 or 32:1).
• Measurements: Each bottle is 12.8 fl oz; six bottles = 76.8 oz total, enough to treat about 30 gallons of fuel (at 50:1). No mixing required—just pour the entire bottle into 1 gallon of unleaded gas (87 octane or higher, no ethanol preferred).
• OEM vs Aftermarket: This is genuine STIHL oil, not a generic substitute. If your machine is under warranty, using STIHL oil is often required to maintain coverage.

Key Things to Know

• No mixing guesswork: Each bottle treats exactly 1 gallon of gas. Use the whole bottle to avoid ratio errors.
• Synthetic blend: Reduces smoke, deposits, and wear vs. conventional oil. Good for high-RPM applications (chainsaws, leaf blowers).
• Shelf life: Store in a cool, dry place. Unopened bottles last 3–5 years; once mixed with gas, use within 30 days.
• Not for 4-cycle engines: This is strictly for 2-cycle air-cooled engines. Using it in a 4-cycle mower will cause damage.

Should You Buy It

Buy if you own one or more STIHL 2-cycle tools and want a convenient, pre-measured, OEM-recommended oil that simplifies mixing and protects your engine. It’s also a solid choice for other 50:1 equipment if you prefer a proven synthetic blend over generic options. For occasional users, a single bottle may be more practical than the 6-pack.
