Hey guys, my neighbour just bought himself a 2nd hand etec, the engine report under oil ratio only shows TC-W3, nothing else, so how would he now know if the motor was set to use XD100 or XD50?
Contrary to the misinformation on the internet and "dock talk", with your motor set for TC-W3 you can run any NMMA certified TC-W3 oils safely and even XD-100 if you wish. You do not have to reset the motor for XD-100.
Be aware that Evnirude also specifies using XD-100 in cold weather to avoid oil thickening and flow problems.

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.
What will it show on the engine report if it is set to XD100?
The two engine oil settings are tcw3 which means you can use tcw3 plain oil or XD50 synthetic blend.
The other setting is XD100 for full synthetic oil only.
While an Etec can run plain tcw3 the XD50 is better and about the same cost.
Not sure of your neighbor's motor model, but if set to the XD100 setting, there should be a tag under the cowling that states XD100 setting. On my newer 150hp motor, the tag is on the port side of the engine.
Thank you, I will ask him to have a look under the cowling to see if there is a tag.
