Keep all filters clean, and change on a regular bases. Tire pressure, and alignments, are also a factor.Your going to get different ideas about this, but this is basic things to do.

i keep up on the tire pressure the're supose to be at 35psi for the vehicle but the tire says 50psi so i keep them at 40psi and change the fram air filter when needed but was thinking of a less restrictive air filter like a fram airhog or K&N or something. plus i change my oil every 3000 miles and i switched from valvoline to mobil 1
