My grandpa is a man of tradition. He is one of those people who feel like the old way may have been a much better way than the way people do things now. He is always the last to switch to something new. For example, he didn’t get email until recently. The same holds true for the way that he takes care of his boat and its outboard motor.
Last time he was in the marina shop nearest to his home, there was a whole display touting some brand new type of motor oil. The salesperson really wanted to get him to buy it. He was trying to explain how it was great oil. In the end, my grandpa went with what he always gets, because he knew it was the best outboard motor oil for him.
