check your air filter
change your spark plugs
check tire pressure
don't drive around with unnecessary weight
keep your foot out of the skinny pedal
all easy things to do to improve/keep your MPG consistent.
Yeah I kinda figured in a way, and I've done about all that except for spark plugs and i haven't checked my tire pressure lately…. prob should do that, also would adding an extra 5 pounds of air help? it helped with my old dakota and i would assume it would do the same in the ram
