Hello all soo recently I have realized that my tank has been coming to an end quite quickly. I have wasted half a gallon driving maybe a little less then 100 miles today. Before one tank would last me almost 2 weeks and now its going to about a week or less. I have a D1 with 245's no other mods other then a light bar with lights. Now is there anything that can be done to squeeze a little more out of it?computer problems?..will changing the air filter do some work?


thanks all

 

What is your actual MPG?
I average 14.9-15.2 on a weekly basis.
Thats 50/50 city/expressway driving.
