44psi General Altimax HP tires (for cheap & quiet)
Castrol 5-30W motor oil (less friction than 10-30W, much cheaper than syn oil)
Bosch platinum spark plug ($2 each, cheap and last)
Lower grille blocked (the fan is on too much in city driving if both grills are blocked, Lower grille blocked is cooler than upper grille blocked)
Mobil1 synthetic gear oil
Scangauge II (gives me 7.5% mpg boost and drive faster)
Install rear Monroe shocks for smoother ride.
My goal is 40+mpg consistenty, 45mpg max.
