Stihl Premium 2 Cycle Oil 6-Pack 50:1 Mix Bottle 100mL for 5 Liters (3.4 oz for 1.3 Gallon)

What It Is

Stihl Premium 2-Cycle Oil is a high-quality, pre-measured 100 mL bottle designed to mix with 5 liters of unleaded gasoline at a 50:1 ratio. It’s intended for all Stihl 2-cycle engines (chainsaws, trimmers, blowers, hedge trimmers, and cut-off saws) and compatible with other brands requiring a 50:1 mix.

Fitment & Compatibility

• Check your engine’s mix ratio: This oil is for 50:1 (2% oil) engines only. Do not use in engines requiring 40:1, 25:1, or other ratios.
• Fuel capacity: Each 100 mL bottle treats exactly 5 liters (1.32 gallons) of gas. If your machine’s tank is smaller, you’ll have leftover mix—store it in a sealed, labeled fuel can.
• Brand: Works in any 2-cycle engine that calls for 50:1 mix (Stihl, Husqvarna, Echo, Ryobi, etc.). Not for 4-cycle engines or diesel.
• Measurement verification: The bottle has a built-in measuring window, but if you’re mixing less than the full bottle, use a separate graduated cylinder or syringe for accuracy.

Key Things to Know

• Pre-mixed convenience: No measuring cups needed—just pour the entire bottle into 5 liters of gas. For smaller batches, the bottle’s markings allow partial use, but it’s easy to over- or under-mix if you’re not careful.
• Quality: Stihl’s oil is a synthetic blend with high detergency and low ash, reducing spark plug fouling and carbon buildup. It meets ISO-L-EGD and JASO FD standards.
• Installation difficulty: Trivial—just pour oil into gas can, shake, and fill your tank. No tools or special skills needed.
• Gotcha: This is not pre-mixed fuel. You must add it to gasoline yourself. Also, ethanol-blended gas can absorb moisture over time, so use your mix within 30 days.

Should You Buy It

Buy this if you own one or more Stihl 2-cycle tools (or any 50:1 engine) and want a foolproof, no-measure mix that’s proven to reduce engine deposits and extend life. It’s slightly pricier than generic oil, but the convenience and reliability are worth it for anyone who values engine longevity over saving a few bucks.
