over the last few days it seems to have gotten kinda bad. it feels almost as if my car is dragging a weight, its harder to get up to speed and slows down quickly when coasting. also my mpg i thought was low because of blaring the heat and what not but im starting to doubt it. normally i run at 32 33mpg right now im down to 28.... and its been slowly going down to that starting about a week ago. anyone have any idea? my oil life is at 50% (my usual chaining point appointment on friday) but theres nothing else i can think of. my ebrake is off by the way.

I usually get around 32 mpg also, and it dropped to 28 after I put in bad gas like @webby suggested. After your tank is empty I would try and put in 91 or 93 gas and then reset the mpg display to check if that made a difference.
Also I had been letting my car idle quite a bit to warm up and still doing some driving while the engine was cold in these subzero Antartic blizzard temperatures so that might have something to do with yours as well
 
i think the drop started more than a week ago after i was thinking of it and ill be gassing up today so wel see. also i get gas from the same shell every time and ive never had a problem but i do understand they could have gotten a bad batch.

il give that a shot
 
Wouldn't hurt to put about 5 ounces of "Seafoam" in it with a full tank(gets rid of moisture).

You'll see the best results on the next tank full, after running the Seafoam.....

Ours started dropping in early December. It's colder this year and on short trips (Cheshire to C. J.'s etc) we're down to about 30 mpg vs 32 last year.
