Low gas miles
First off, I love this website. Anytime I have problems, someone here has
always given me a solution!
When I first got my car, it was getting almost 350 miles to a tank of gas.
Lately, I am lucky if I get 250. I understand there is additives added to the
gas in New England to help prevent freezing in cold, that lower gas miles,
but this is ridiculous.
Somethings I have done to try and better gas miles were, replaced tires,
aligned the vehicle, replaced PCV hose, MAF sensor.
I have noticed the car runs at a higher RPM, especially at highway speeds.
So what I am asking is, what other things can I do to try and better my gas
miles, or find out why it is burning through so much gas.

the handbrake might be left on partially~
It is possible for some reason the transmission is slipping or not going into overdrive. That would explain the higher rpm noticed on the highway. It needs to go to a reputable mechanic for proper diagnosis.
What trouble codes came up when you had it scanned?
