This tool determines the precise proportions of gasoline and oil necessary for two-stroke engines that require a 50:1 fuel mixture. For example, if an engine’s fuel tank holds one gallon (128 ounces) of gasoline, it would require 2.56 ounces of oil to achieve the correct mixture. Deviation from this ratio can negatively impact engine performance and longevity.
Maintaining the correct blend ensures optimal engine lubrication, preventing premature wear and potential seizure. Historically, achieving this ratio accurately relied on manual measurement, increasing the risk of error. These devices streamline the process, offering convenience and reducing the likelihood of improper mixing, ultimately extending engine life and minimizing maintenance requirements.
