Fully Synthetic 2-Cycle Engine Oil - 6.4oz Mix Bottle 0781-313-8008, 0781-313-8010 Compatible with Stihl, Husqvarna, Echo and More, OEM (6.4 ounce bottle, Box of 48)

What It Is

This is a fully synthetic 2-cycle engine oil in a 6.4-ounce squeeze bottle, designed for pre-mixing with gasoline at a 50:1 ratio. It’s intended for use in handheld outdoor power equipment like chainsaws, trimmers, leaf blowers, and hedge trimmers from brands including Stihl, Husqvarna, Echo, and others.

Fitment & Compatibility

• Mix ratio: All engines require a 50:1 gas-to-oil mix (2.6 oz oil per gallon of gas). Do not use in 4-cycle engines or mixers requiring different ratios (e.g., 40:1 or 32:1).
• Brand compatibility: Works with any brand’s 2-cycle engine—Stihl, Husqvarna, Echo, Poulan, Ryobi, etc. No OEM-specific additives needed.
• Bottle size: Each 6.4 oz bottle treats 2.5 gallons of gas. The box of 48 bottles is a bulk purchase; single bottles are sold separately.
• Measurement check: The bottle has a built-in mixing cup with markings for 1, 2, and 2.5 gallons. Ensure your gas can’s capacity matches these increments for accurate mixing.

Key Things to Know

• Quality: Fully synthetic means better engine protection, lower smoke, and longer spark plug life compared to conventional 2-cycle oils. Meets JASO FD, ISO-L-EGD, and API TC standards.
• Installation difficulty: Trivial—just squeeze to the correct line in the bottle’s cup, add to gas, shake, and pour into your equipment’s fuel tank. No tools needed.
• Common gotcha: The 6.4 oz bottle is not a single-use container for a full tank. Each bottle treats 2.5 gallons; if you only mix 1 gallon at a time, you’ll need to mark and reuse the bottle (or buy smaller single-use pouches). Also, store oil away from heat and direct sunlight to prevent degradation.
• Shelf life: Unopened bottles last 3-5 years. Once opened, use within 1 year and keep the cap tightly sealed.

Should You Buy It

Buy this if you own multiple 2-cycle tools and want a high-quality oil that reduces engine deposits and extends equipment life. It’s ideal for heavy users who mix large batches of fuel (2.5 gallons at a time) and prefer a single, reliable oil for all their brands. Skip it if you only mix small amounts (under 1 gallon) or need a single-use packet for occasional use.
