XD100 or XD50?

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?

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.

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.

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.

What will it show on the engine report if it is set to XD100?

Thank you, I will ask him to have a look under the cowling to see if there is a tag.

The engine report will say XD-100 if it is set for XD-100 only use.
A tag on the engine should be an indication but the engines are shipped with a tcw3/XD50 tag on them. It is up to the dealer to change the tag if they change the setting to XD-100. So an engine report is the only way to know for sure. There are many owners that choose to run XD-100 and leave the engine set to the tcw3 ratio.
