05-10 tacoma Prerunner 2.7L 5sp. xcab. MPG???

Hello to all the Tacoma lovers. This question is for the Tacoma owners with the Prerunner 2.7L 5sp. xcab, curious how many miles you guys are getting on a full tank. As for me I get around 300 miles on a full tank before the gas light comes on,with city/highway.driving condition-highway i get up to speed of 75mph and city i switch gear at around 2500 rpm, so basically i drive pretty slow.I thought i might get better gas mileage with some mods i did like k&n intake and doug thorley headers, before mods i get about 320miles on full tank.drop about 20miles after mods. got 13,000 on odometer so far. so what sup with your guys truck? any better luck?

(before modification.all stock with bull bar,side step and 3inch lift)
math. 320miles/17g=18.82 mpg

(after mods with k&n intake and doug thorley header)
math. 300miles/17g=17.65 mpg

 

i get 18mpg's with my V6 AC
