For all the different 2 cycle engines that require a gasoline/oil mixture as opposed to having direct injection, utilizing the correct ratio of gasoline and oil can improve fuel economy and performance. While some 2 cycle engines recommend the standard gasoline/oil mixture of 32:1, it’s a better idea to check the manual before committing to a specific ratio. Motorcycles, for example, use 32:1, but some models also use 40:1 or 50:1 mixtures. Most 2 cycle engines recommend a gasoline/oil mixture somewhere in the range of 16:1 to 80:1, though this too can differ. Experts who have conducted research on 2 cycle engines and 2 cycle oil tend to agree that it’s better to err on the side of caution, and use too much oil. Too little oil can result in the engine seizing up and cause serious damage to the internal components.
It’s also important to use the manufacturer recommended brand of 2 cycle oil in the engine. It’s possible to use most brands of 2 cycle oil in a 2 cycle engine, but for the best performance and to reduce the wear on the engine, more specific formulations of 2 cycle oil can provide better results.
