Nissan Repair: gas cosumption, nissan altima, brake caliper

Question
i have a nissan altima 03 sl with 112k miles. its eats alot of gas can someone help me what should i do ??

Answer
The most common cause of excessive gas consumption is a leaking fuel line. Have you checked this, especially if you are smelling fuel?

If that is OK, here are more gas guzzling culprits:

Engine tune up - spark plugs especially
slipping transmission
underinflated tires
brake caliper binding

Hope this helps -
