Last weekend I changed the oil with Mobil 1 5w-30 and an M1 EP filter. Today, I winterized the exterior and detailed the interior. 1) New Rain-X latitude wiper blades 2) Wax Job 3) Rain-X treatment on all exterior glass 4) Eagle One wheel protectant 5) Ice scraper, heavy blanket, ect in the trunk. 6) Filled the washer fluid resevoir with Rain-X washer fluid. Living in Divide Colorado at 9200 feet, the weather here is getting chilly fast. Wednsday we are supposed to get 3-7 inches of snow with a low of 7 degree's that night. Today is beautiful, so now is the time to get it done.
