An instrument designed to compute the appropriate ratios of fuel and oil necessary for two-stroke engines. This device assists in determining the precise quantities needed to achieve optimal engine performance and longevity. For instance, if an engine manufacturer recommends a 50:1 fuel-to-oil ratio and the user intends to mix 1 gallon (128 ounces) of fuel, the instrument will calculate that 2.56 ounces of oil are required.
Precise determination of fuel and oil proportions is vital for two-stroke engine operation. Insufficient oil can lead to premature engine wear and failure due to inadequate lubrication. Conversely, excessive oil results in incomplete combustion, carbon buildup, and reduced engine efficiency. Historically, reliance on manual calculation and measurement introduced potential for error. Such errors could compromise engine performance and shorten its lifespan, leading to increased maintenance costs and downtime. These instruments offer a more accurate and efficient alternative.
