When I first bought my Evinrude engine, I took the time to find one with the set up that I wanted rather than the one that I would be able to find more quickly. I wanted one that would be set up to use XD 100 oil since this would make the oil consumption lower. I had a hard time finding one that would be programmed this way in my area.
Now that I have the engine that I always wanted, I have been able to drive around in my boat without having it consume oil too quickly. It is great to be able to avoid adding the oil as frequently as I might have to with an outboard programmed to consume XD50. I am glad to be able to use Evinrude XD 100 oil any time that I need to lubricate the engine.
