I started using Sears lawncare products 18 years ago. My leaf blower, string trimmer and chain saw all use a 40:1 ratio. The chain saw still runs great and other two lasted 14 years before buying new Craftsman replacements. I attribute the longevity to this 2 cycle oil. Minimal smoke while running and pre measured size makes life easy.
