    I get 10 mpg on normal driving and longer drives 11 to 12 and if i’m pulling as little as 5 usually 8.

    I don’t have the 2500 but I do have the 1500 and just had the plugs and wires done after 97,000 miles. My mialage also decreased.

    Why is that?

    Must be the wrong wires, plugs or spark plug gap?
