2008 E-tec 300

Can I use twc3 in the Etec? I have Xd100 but I need to pump the tank out to remove the twc3

TC-W3 certified oil can be used in the Evinrude E-TEC engines as long as the EMM oil programming is at the TC-W3 setting. A dealer technician with the appropriate diagnostic software and a laptop can check the setting and change it from XD-100 to TC-W3 if needed.

There is no way to tell the oil programming setting without the proper software. See a dealer first before changing your oil from XD-100 to a TC-W3 to avoid engine damage.

After determining that your motor is set for TC-W3 lubircant, you may want to switch to Evinrude's XD-50 which is a synthetic blend that is less expensive that the fully synthetic XD-100.
