could there be something wrong?

yeah, last time i checked i was getting about 17 MPG, i run amsoil P.I. cleaner in my fuel, plus i change my oil with amsoil, just rencently had a tranny flush, thats just about it, ok maybe i was wrong about the milage i think its about 40 or so but still, do you think i just just go all out and replace everything the diff fluids/transfer care fluid, belts, and a fuel induction service? i'll get gas tomorrow and write everything down then the next time i get gas i'll figure out what i am averaging, i love my truck and would hate to let it go but every day a spec v sentra sounds better and better.

You sure someone didn't steal some?

Only thing I could think of is something may be wrong with the sensor and the gauge. Your truck isn't lifted or have huge tires so with your exhaust and intake you should have pretty good gas mileage. Try and keep it under 3000rpms and see how that helps and clean your MAF, mine was insanely dirty when I cleaned it today.

thrusday im off work so i may swing by the auto store and pick up a can of CRC and clean it out, may also sometime soon make an apointment at the dealer and have them do a BG power induction serivce maybe along with new drive belts see what that does, but i will deff do the mass airflow clean, i perhaps wouldn't have clogged cats would i?

i dont kno if you missed my post, or just plain dont wanna listen to my advice... ill lay money that its a knock sensor

it doesnt throw a CEL but will kill your gas mileage

the first thing you should always do is have your truck plugged in when somethings not right

It would help to know how many gallons you had to refill for that 25-30 miles.. i mean if you have something wierd with your fuel guage(like its actually reading correctly, unlike all of our other frontiers) if that 30 miles is only 2 gallons of gas then your getting 15 and thats what I get... note the fact that im 4X4 though

I travel about 40 something miles to the city and back just about every day and I only use about 2 gallons each trip

Are you sure no one is siphoning gas out of your gas tank??? At $4.00 plus a gallon it would not surprise me.
