Fully Synthetic 2-Cycle Engine Oil - 2.6oz Mix Bottle 0781-313-8002, 0781-313-8004 Compatible with Stihl, Husqvarna, Echo and More, OEM (2.6 ounce bottle, Box of 48)

What It Is

This is a case of 48 pre-measured 2.6 oz bottles of fully synthetic 2-cycle engine oil, designed for mixing with unleaded gasoline at a 50:1 ratio. It’s intended for use in handheld outdoor power equipment like chainsaws, trimmers, leaf blowers, and hedge trimmers that require a 2-stroke oil mix.

Fitment & Compatibility

• OEM Compatibility: Husqvarna part numbers 0781-313-8002 and 0781-313-8004. Also works with Stihl, Echo, Poulan, Ryobi, and most brands that specify a 50:1 mix ratio.
• What to check: Verify your equipment’s fuel-to-oil ratio requirement. This oil is pre-measured for 50:1 (2.6 oz per 1 gallon of gas). Do not use in 4-stroke engines or equipment requiring a different ratio (e.g., 40:1 or 32:1).
• Measurements: Each bottle is 2.6 fl oz (77 ml). The case contains 48 bottles. No additional measuring needed—just empty one bottle into 1 gallon of fresh unleaded gasoline.
• OEM vs Aftermarket: This is Husqvarna OEM oil, not a generic substitute. It meets ISO-L-EGD and JASO FD standards, which are higher than basic API-rated oils.

Key Things to Know

• Quality: Fully synthetic formula provides better engine protection, reduced smoke, and cleaner combustion compared to conventional 2-cycle oils. Suitable for high-RPM, air-cooled engines.
• Installation difficulty: Trivial. Pour entire bottle into 1 gallon of gas, shake, and use immediately. No measuring or mixing math required.
• Common gotchas: Do not store pre-mixed fuel for more than 30 days unless you add a fuel stabilizer. The 2.6 oz bottle is designed for exactly 1 gallon—using it with less or more gas will alter the ratio and risk engine damage.
• Price note: At $169.95 for 48 bottles (~$3.54 each), this is a bulk purchase. Cheaper per bottle than buying singles, but only makes sense if you go through a lot of mix or share with multiple users.

Should You Buy It

Buy this case if you own multiple 2-cycle tools and burn through at least a few gallons of pre-mix per season—the per-bottle savings add up, and the synthetic formula is genuinely better for engine longevity. Skip it if you only mix a gallon every few months; a single bottle or a quart of concentrated synthetic oil is more economical and won’t go stale.
