I'm going to have my dealer set my new eTec 75 for XD100 but I'm going to run the first reservoir of oil as the factory oil. Is this how it is normally done? I would have thought that the stock oil would have to be drained and replaced with XD100. I know these machines have a computerized break-in period where they use more oil at first.<br /><br />I called evinrude(bombardier) and they said it wouldn't hurt it to have the computer programed for XD100 but running the stock oil at first. Just wanted to see what you guys thought of the idea.<br /><br />What do these outboards come with from the factory? XD50?
