| 22,000 miles and I get 11 towing a 13,000lb 5th wheel, 13 around town and 16 on the highway. Much over 65 and it drops to about 14. MPG has gone up since I got rid of my K and N filter. K & N was throwing a code for the air flow sensor. Too much oil out of the box that would gum up the sensor. Dealer would not replace sensor under warranty until I came back with a stock filter. Two friends had same problem. |
