Echo 6450002 PK6 2 Gallon Power Blend Oil Mix (50:1)

What It Is

This is a 2-gallon (6-pack of 32-oz bottles) pre-mixed 50:1 fuel-oil blend for Echo 2-stroke engines—trimmers, blowers, chainsaws, and edgers. It eliminates the need to measure and mix your own gas and oil.

Fitment & Compatibility

• Engine types: Only for air-cooled 2-stroke engines requiring a 50:1 ratio. Not for 4-stroke or older 2-stroke engines needing 40:1 or 32:1.
• Brands: Echo-approved, but also works in any 2-stroke tool that calls for ISO-L-EGD or JASO FD oil (e.g., Husqvarna, Stihl, Shindaiwa, Ryobi).
• Fuel requirement: Must be mixed with unleaded gasoline (up to 10% ethanol). Do not use with E15 or higher ethanol blends.
• Storage: Use within 30 days of mixing; shelf life is shorter than fresh mix. Store in a cool, dry place away from direct sunlight.

Key Things to Know

• Low rating (2.2/5) likely due to price ($28.99 for 2 gallons) and complaints about the included bottles being hard to pour without spilling. Not a quality issue with the oil itself.
• No measuring needed – each 32-oz bottle mixes with 1 gallon of gas for a perfect 50:1 ratio. Just pour one bottle into a gas can, add 1 gallon of gas, shake.
• Installation difficulty: None – it’s pre-mixed. The only “gotcha” is accidentally using it in a 4-stroke engine (can cause fouling, smoke, and damage).
• Contains fuel stabilizer – helps prevent gumming during short-term storage (up to 30 days). For longer storage, add extra stabilizer.

Should You Buy It

Buy it only if you want the ultimate convenience of pre-measured bottles and don’t mind paying a premium. It’s right for casual users who own a single Echo tool and hate measuring oil. Skip it if you have multiple 2-stroke machines (buy a gallon of concentrated 2-stroke oil and mix your own for a fraction of the cost) or if you need a longer shelf life (use a synthetic mix instead).
