Got done mowing today and while blowing it off decided to check fluid level in tank and notices little bit of white milky sludge on cap. Now I changed fluid last spring and it has about 28 hrs on it and its kept under a shed so I figure its the humidity here in Georgia. I shined a light inside the tank and it looked ok but I know that's not a really good way to check for water in it. Should I go ahead and bite the builett and go ahead and change or it some moisture collecting under cap...normal? Thanks Oh this is on my 2012 DC Silver Eagle 2760
