Hey folks- looking for opinions. I changed my oil today during winterizing. i have a 99 215 Express with a carborated 305. I have been using Quicksilver sinthetic blend 25w40. I mistakenly bought a gallon of 25w50 and a quart of 25w40. So now I have 4 quarts of 25w50 and 1quart of 25w40 in the boat now. I didn't realize until after the job was completed I mixed the oil weights. Should I just run it in the spring or should I change it? Pressure seamed fine when I ran it on the hose and muffs. :huh:
