The instrument is a tool designed to determine the correct proportion of lubricating oil that must be mixed with gasoline for two-stroke engines. For instance, a setting of 50:1 indicates that 50 parts of gasoline should be mixed with one part of oil. Improper ratios can lead to engine failure.
Accurate mixture calculation ensures optimal engine lubrication, preventing excessive wear and potential seizing. Historically, relying on estimations or improper mixing has been a prevalent cause of two-stroke engine malfunctions. Using the correct ratio extends engine life, reduces emissions, and maximizes performance. Furthermore, following the engine manufacturer’s recommended ratio is critical for warranty compliance and dependable operation.
