When I made the switch to a Mercury engine for my boat, I knew that I also needed to switch the type of oil that I was using. My new engine required an oil that could be used in direct injection applications rather than one that required the oil to be mixed directly into the gasoline in order to be used properly.
Since I knew that I was using a Mercury outboard motor, I determined that it would be a very good idea to choose direct injection oil that was made by Mercury. I ended up picking out a Mercury two cycle oil the exceeded all of the recommendations for use with my engine. I was very happy with the way that the oil worked when I put it into my engine.
