This is my first powerstroke I have had it for about 7 months now. When I bought it was getting about 17-18 miles to gallon. Changed my oil and Fuel Filter and am now curently getting about 14 I dont have a clue on why. Also I curently have about 97000 on it what is coming up that I need to do for regular maitnance. Need help Really dont know to much about them other than changing the oil every 3 to 5k. Thanks
