The spark plugs will not make the truck jump off the line but they do help burn the fuel faster and efficiently, so you might get 1 more mile to the gallon. Lowing the temperature by 15 helps from loosing HP. A little here a little there and before you know it You are going longer between pumps.
Lets say you improve by 5 mpg. 30 x 5 = 150 more miles to a tank.
