So I usually get about 380 miles for a full tank and lately I have been getting about 250 for a full tank. Most of my mileage is highway too. What reasons could gas be getting cut down so badly?

Have you done anything to your car since the last time you got 380 miles to your tank? I can think that the cold weather might be playing a role here, but I can not see a loss of 100 miles. Are you letting your car idle to warm up? Is your trans really cold when you are on the highway? My tcc does not lock up until the trans temps are around 100*F

how many miles are on your car? could be an O2 senser

I would say cold weather is the culprit.

Also if your air in your tires are messed up it will take away your gas! Or check your airbox/filter and make sure everything is clean. I never heard of 100mpg loss...butttt those are just some things to check.

My car has done the same things. I am now getting around 13-14 mpg in town instead of 18-22. An 02 sensor could be the culprit? The car is stock and has had a tune up done on it. Also I recently had the lower intake manifold gaskets done at the stealership.

Fuel pressure regulator. pull the vacuum line off the top of it while motor hot and running, check for fuel smell inside port, or wet gas dripping out of line.

Interested to see what comes up out of this. I have been noticing the same problem. Mine is a bit better after replacing the maf due to other issues, but I don't know if it's just the cold weather bringing my milage down so much.
