cold weather operation
the E-TECs come from the factory setup for regular TC-W3 oil. In cold weather, just use the XD-100. To make things simpler, just use XD-100 synthetic oil all the time and have the motor set for the "reduced oiling" programming.
For freezing weather operation (32°F - 0°C), ALL oil injected Johnson and Evinrude engines require the XD-100 oil, not just E-TEC.
