So this weekend i decided to drive home to visit the family in my 97 Tahoe 4x4, but i only averaged around 16mpg....what could it be? the trip was was mainly all highway. I averaged about 75mph. oh and i filled up with 88 rated fuel on the way there and 87 on the way home and noticed no difference?
any ideas are welcome.

Is this a recent development? Have you generally had better mpg, or does it just seem low to you? Depending on the gears you have at 75 mph you may have done pretty well.

i've got the 5.7 liter (350ci)
its not a dirty air filter installed a new one when i got the rig at the end of august.
I bought the Tahoe from my uncle and he told me he would average like low 20's on the highway.
I have the Tahoe sport LT (2 door) 4x4
