High Performance 2-Cycle Engine Oil - 6.4oz Mix Bottle 0781-319-8015, 0781-319-8009 Compatible with Stihl, Husqvarna, Echo and More, OEM (6.4 ounce bottle, Box of 48)

What It Is

This is a high-performance 2-cycle engine oil pre-mixed in a 6.4-ounce bottle, designed for use in gas-powered lawn equipment like trimmers, chainsaws, leaf blowers, and hedge trimmers that require a 50:1 fuel-oil ratio. It’s suitable for both air-cooled and water-cooled 2-cycle engines.

Fitment & Compatibility

• Brand compatibility: Works with Stihl, Husqvarna, Echo, Poulan, Ryobi, Troy-Bilt, and other major brands using 2-cycle engines. Not for 4-cycle engines or diesel.
• Fuel ratio: Intended for 50:1 (2.6 oz oil per gallon of gas). Do not use for 40:1 or 32:1 mixes unless you adjust the ratio separately—this bottle is pre-measured for 50:1 only.
• Engine types: Air-cooled engines (most handheld equipment) and some water-cooled (e.g., outboard motors) are compatible. Check your manual for required oil type (API TC, JASO FD, or ISO-L-EGD).
• Measurement check: 6.4 oz bottle treats 2.5 gallons of gas at 50:1. If your tank is smaller (e.g., 1 gallon), you’ll over-oil unless you measure partial amounts.

Key Things to Know

• Quality: High-quality synthetic blend reduces smoke and carbon buildup, extends spark plug life, and meets or exceeds OEM specs for Stihl, Husqvarna, and Echo.
• Installation: No special tools—just pour the entire bottle into 2.5 gallons of unleaded gasoline and shake. For smaller batches, measure using the bottle’s markings (if available) or a separate measuring cup.
• Common gotcha: The bottle is pre-measured for 2.5 gallons. Using it with less gas (e.g., 1 gallon) will create a rich mixture that can foul plugs and cause poor performance. Always mix with the exact amount of fuel specified.
• Storage: Keep sealed and away from heat sources. Once mixed, use within 30 days or add a fuel stabilizer.

Should You Buy It

Buy this if you own multiple 2-cycle tools from different brands and want a single, high-quality oil that meets OEM standards. It’s ideal for heavy users who can burn 2.5 gallons of mix regularly. If you only need small batches (e.g., 1 gallon), consider a smaller bottle or a different product to avoid waste and rich-mixture issues. The price reflects a box of 48 bottles—good value for pros or shared use, but overkill for a single homeowner.
