Proper Gas to Outboard Motor Oil Ratio

While most vehicles now utilize four-stroke engines, the two-stroke model does have its advantages. Two-stroke engines complete the thermodynamic cycle in two movements, creating greater high specific power and making them much more efficient than their counterparts. Unlike four-stroke engines that house the gasoline and Evinrude XD 100 oil separately, two-stroke motors have traditionally required a mixture of the two.

This has been one of the main drawbacks of the motor, as it results in total-loss system where all of the oil is burned. Typically, engines use a ratio of 50 parts gasoline to one part oil, but new technology has allowed for two-stroke engines that don’t require a mixture. Although these models still result in a tot-al loss of oil, they are more ecologically friendly than their predecessors.
