hey guys, (

like i said im new here and i don't really know where my question would fit. but i've been on this post for a while now. i drive a 07' sparkling graphite metallic 328i AT. i have about 63,000 miles on it, since it's my daily drive. it's pretty much stock until my car can run smoothly again. but my question is,

i've been driving around for a couple of weeks now and i noticed that my avg gas milage is only 19.2. i would fuel up the whole tank and it would be gone in a 2 to 3 days. the max milage on a full tank is around 310 miles..when i USED TO GET 370-400 miles on avg. what can i do to fix this problem?

i will post pics when i mod it up. rims, h&r, intake, m-tech front bumper for now
(i already got tints, muffler delete, performance brakes, 8k HID headlights and fog, and new tips)

Maybe it needs a tune up, does the RPM gauge move around alot when at a stop light while the engine is running? Does the engine have a rough idle?
Has your driving habits changed?
When was the last time you had your air filter changed out?

These are ALL things that impact your MPG performance.

Welcome. You should definately check all those things and maybe try using a fuel system cleaner like techron. Speaking of fuel, what octane fuel are you running?

Nr!qUe · 06-08-2010, 12:59 PM

the mileage you used to get sounds like pure highway mileage. I avg 360 miles per tank. almost exactly every time. I drive mostly highway though. maybe you changed a driving habit? maybe you changed your route? maybe you changed fuel type? maybe you have a bike rack on it causing drag? maybe you're using more A/C? I dont know what to say.

Keep your foot off the gas...

I average about 410 miles per tank purely highway miles!
