I saw on one of the posts where you guys were talking about the price of the oil. $30 a gallon for the XD-100. My question stems from having no boat experience. I have ridden 2 stroke dirt bikes my whole life and a pint is only good for about 4 gallons of gas. So am I going to be buying a gallon of this stuff every time I fill up the gas tank? How long does a gallon of oil usually last on a 2000 225 ficht? Thanks guys and Happy New Year to all.![]()
