Stihl MotoMix 50:1 Premixed 1 Quart (32 oz) Non-Ethanol Fuel — HP Ultra Synthetic Oil, Ready-to-Use

This premixed quart is formulated to take the guesswork out of fueling small engines that require a 50:1 mixture. Packaged in a convenient 32 oz can, MotoMix uses non-ethanol, low-aromatic fuel and a fully synthetic, biodegradable oil to preserve engine cleanliness and stability. Because it arrives pre-blended to Stihl's specifications, it simplifies fueling and supports consistent performance across seasonal use and storage.

How does MotoMix simplify fueling for 2-stroke equipment?

MotoMix arrives ready to pour at the precise 50:1 ratio, so you don’t need measuring cups or separate oil bottles. It removes variability in field mixing and reduces the risk of incorrect ratios that can harm engine life or performance. The sealed can also helps prevent fuel contamination during storage and transport.

• Pre-blended 50:1 ratio for compatible 2-stroke engines
• No measuring or separate oil mixing required
• Factory-sealed for consistent fuel quality

What makes this fuel stable for long-term storage?

The formula uses non-ethanol gasoline and stabilizing additives that limit chemical breakdown over time. Stihl states that the product remains stable for up to two years after opening when stored properly, so it’s suitable for seasonal equipment that sits idle for months. That stability helps reduce starting problems after storage.

• Non-ethanol fuel resists phase separation
• Low-aromatic gasoline chosen for stability and cleaner burn
• Factory blend reduces degradation from incorrect oil-to-gas ratios

Why does Stihl use HP Ultra oil in this blend?

Stihl pairs its high-grade synthetic HP Ultra oil with gasoline to provide consistent lubrication across a range of operating conditions. This oil is engineered to protect moving parts in 2-stroke engines and to minimize deposits compared with lower-grade oils. Using Stihl’s controlled oil formulation helps ensure compatibility with the brand’s recommended engine tolerances.

• Fully synthetic, formulated for modern 2-stroke engines
• Designed to minimize deposits and wear
• Biodegradable components where feasible
