The term refers to a tool, either physical or digital, used to determine the correct proportions of gasoline and oil required for two-stroke engines. A “32 to 1” ratio signifies that for every 32 parts of gasoline, one part of oil is needed. For example, mixing 32 ounces of gasoline with 1 ounce of oil yields a 32:1 ratio suitable for certain two-stroke applications.
Achieving the precise fuel-to-oil ratio is critical for the proper lubrication of engine components. Insufficient lubrication can lead to increased friction, overheating, and ultimately, engine seizure and failure. Conversely, an overly rich oil mixture can cause excessive carbon buildup, reduced engine performance, and increased exhaust emissions. Historically, understanding and calculating these ratios was a manual process, prone to error. This tool improves accuracy and reduces the risk of engine damage or sub-optimal operation.
