gas mileage

Hey guys, I have an 01 gt. I changed the fuel filter for a standard motorcraft one(also used a fuel system cleaner) and suddenly my car has started to waste gas like crazy. I haven't tested the mpg yet but I don't think taking a 30 minute drive on a highway should waste almost a quarter tank...

Hello all, :) I'm new to this site, and I was wondering what the average mpg is for users on here who drive v6 mustangs? I purchased a v6 rather than a GT hoping the gas mileage would be better, but now a few people I know have early 2000's GT's that get better gas mileage than my 2003 v6...

I have a 2003 coupe 112k on it. My gas mileage is terrible. A full tank and my gas light is on between 180-200 miles I don't drive the car hard at all. I would guestimate i used to get around 240 - 260. The car got new plugs, wires and fuel filter at about 85k I just replaced my bad coil pack...

Vortec cyclone, just install it into your cold air intake and presto! Instant horsepower, and improved gas mileage! Really?? Is this for real?

So I recently put a short ram intake on my mustang. Removed the stock intake, which was connected to the (charcoal canister?). My Question is, do I rlly need this connected? I want decent gas mileage as money's tight, but I love my intake. If this needs to be connected, is there a way to...

Im thinking of buying a SCT tuner for my 2000 GT, but am wondering if it is worth it? I have the usual bolt ons. Will I see a noticable increase in power? Gas mileage? Can the SCT SF3/X3 tuner also do things like change tire RPM's? Thanks!

I know this is about as vague a question as you can get, but here goes: If the engine is running great (no hesitations, stalls etc), and the timing is set right, everything is gapped properly, and I've started driving without putting my foot in the carb, what would cause a rather painful 8 mpg...

My 5.0 is getting a nasty 10 mpg... I am pretty sure it is running rich cause I can smell it and if I rev it up past 3 grand and then let off I get some popping out the exhaust (sounds like small backfires). The timing is somewhere between 10* - 14* btdc... What can I do to get the car to run...

I just took my first Mini-Trip with my 4 day old, 300-miles on the Odometer, 2011 GT with 6M Transmission. Car is NOT broken in yet. Here are my results. Am I dreaming? Filled up with gas. Topped it off. Drove 30 miles at 40 mph on state roads Drove 76 miles at75- 80 mph on the Interstate...

Hey folks, Here is the situation, my mustang right now is getting ~200 miles to a TANK! Recently I diagnosed a bad canister purge valve, which I haven't replaced yet. Could this be the reason (or part of) for such poor gas mileage? I've looked, listened, and smelt around the engine bay...
