I usuual yuse a " Premum" brand, like Shindiawa, Husky or such, that are pre measured for the specified ratio, like 50-1. It costs a few cents more, but is much more conveniant, is a quality product, and eliminated having to measure out to get the desire ratio when your pumping gas, or trying to mix it during the snow. Im a heavy user, and still only go through 6 or so bottles a year.
