i get about 16/17 mpg in my 2002 v6 auto..

i also have 245 35 20s as a result there is a 2.5 mile speed difference in 10 mile calculation. so every 100 miles i so i add 10 to my overall calculations and i come up with 18/20. does that make sense?

i changed my air filter recently and it was completely black. i guess it was never changed before i got it. i plan on doing the spark plus and wires soon. will those 2 make any difference? i am on a budget and i can not afford a full time up..

any suggestions on prioritizing my tune up?
