I have been noticing my economy getting worse again. Yesterday i did a rough calculation and got 12.4 mpg on the highway. But we did have freezing temps and i had a decent head wind. My radiator is a two row instead of the standard single row. I dont think my truck ever got up to temp cause i was freezing even with my heater on, heater wasnt doing anything. No check engine lights, i just had to redo brakes all the way around. Im thinking i need to seafoam fog it to clear out the intake and exhaust. Maybe pull plugs and see if shes ready for a tune up?
