VP Racing Fuels 6815 SEF Multi-Mix - Universal Outdoor Power Equipment - 40:1/50:1 Premixed 2-Cycle Fuel, 3 Pack

What It Is

This is a premixed, ethanol-free 2-cycle fuel blend (VP Racing Fuels 6815 SEF Multi-Mix) designed for small engines that require a 40:1 or 50:1 gas-to-oil ratio. It’s a universal fit for trimmers, blowers, chainsaws, and other handheld outdoor power equipment.

Fitment & Compatibility

• Fuel ratio: Works for both 40:1 and 50:1 engines (no mixing needed). Check your owner’s manual for the correct ratio—if it calls for 32:1 or 100:1, this won’t match.
• Engine type: Only for 2-cycle, air-cooled engines. Not for 4-stroke or water-cooled equipment.
• Ethanol sensitivity: Safe for any engine that requires ethanol-free fuel (common in small engines to avoid gum/varnish). No compatibility issues with brands like Stihl, Husqvarna, Echo, or Ryobi.
• Storage: Pre-mixed and sealed; no need to add oil. Use within 2 years of purchase date (check bottle stamp).

Key Things to Know

• No mixing required – Just pour and go. Eliminates guesswork and oil separation issues.
• Ethanol-free – Prevents fuel system corrosion and carburetor clogs, especially in seasonal equipment.
• Shelf-stable – Stays fresh for up to 2 years unopened; 6 months once opened if sealed tightly.
• Cost vs. DIY – More expensive per gallon than mixing your own, but saves time and avoids mixing errors that can damage engines.

Should You Buy It

Buy this if you want zero-hassle, consistent fuel for 2-cycle tools and don’t want to measure oil or deal with ethanol damage. It’s ideal for occasional users, rental equipment, or anyone storing equipment over winter. Skip it if you mix your own fuel cheaply or need a different ratio.
