Do not forget that your operators guide states that you have to use XD-100 in freezing weather for proper lubrication.
When operating in conditions under 32°F
(0°C), Evinrude XD100 oil must be used.
The following 2–stroke outboard oils are recommended
for use in your Evinrude E-TEC
• Evinrude XD100 Direct Injection Oil
• Evinrude XD50 2–Stroke Oil
• or a synthetic TC-W3 NMMA-certified oil
Evinrude XD100 oil is preferred for your
Evinrude E-TEC G2 outboard. This synthetic
formula oil provides uncompromised lubrication
and superior performance, even in
extreme conditions especially in cold temperatures
down to 0°F (-17°C).

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.
The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
Just cannot see why one would choose to use 50/50 vs 100% synthetic.
