Stihl 7010-871-0203 MotoMix Premixed Fuel 50:1 (1 Quart)

What It Is

Stihl MotoMix is a premixed, 50:1 ethanol-free fuel blend designed for 2-cycle Stihl outdoor power equipment (trimmers, blowers, chainsaws, hedge trimmers) and compatible with any air-cooled 2-cycle engine that requires a 50:1 fuel-to-oil ratio. Comes in a 1-quart (946 ml) container.

Fitment & Compatibility

• Engine type: Only for 2-cycle (2-stroke) engines requiring 50:1 mix. Not for 4-cycle, diesel, or 25:1/40:1 engines.
• Brand/model: Stihl brand, but works with any brand (Husqvarna, Echo, Ryobi, etc.) that specifies 50:1. Check your manual or fuel cap for “50:1” or “2% oil.”
• OEM vs aftermarket: This is OEM Stihl fuel. No fitment issues as long as your engine is 50:1.
• What to verify: Confirm your engine’s oil-to-fuel ratio (look for “50:1” or “2.6 oz oil per 1 gallon gas”). Do not use in 4-stroke engines or equipment with a separate oil reservoir.

Key Things to Know

• ✅ No mixing required – Ready to pour directly into the tank. Saves time and eliminates measuring errors.
• ✅ Ethanol-free – Reduces carburetor gumming, fuel system corrosion, and starting issues in stored equipment.
• ⚠️ Price per quart is high – About 5–6× the cost of mixing your own ethanol-free gas with quality 2-cycle oil (e.g., Stihl HP Ultra). Only economical if you use small amounts or want convenience.
• ⚠️ Shelf life – Unopened lasts 2+ years; once opened, use within 2–3 months or store in a sealed, cool, dry container.
• 🔧 Installation – Zero difficulty. Just open, pour, and run. No tuning or adjustments needed.

Should You Buy It

Buy MotoMix if you run small 2-cycle equipment infrequently, want to avoid ethanol damage, or hate mixing gas. It’s ideal for seasonal users, occasional trimmers/chain saws, or anyone storing equipment for months. If you burn through gallons each season, mixing your own ethanol-free fuel is cheaper and equally effective.
