MPG Woes
#11
Hmm.. So 25 MPG + 18" wheels is possible with the 4.0. @akdoggie, what tune are you running and did your "S/D Coil w/Live Wires" make any change what so ever.
@waykooljr good idea, I have not checked since they were put on about a month ago. I hadn't seen the tire pressure light so I haven't really worried about it.

I'm currently having my CS/GT front fascia painted, then I'll install it. I'm also installing an ambient console (09 Mustang donor), just waiting for factory connectors to attach the front footwell lights. I'm also putting ambient (7 color) LED's into the door pull pockets.

Ugh... well congrats everyone on your awesome gas mileage. Looks more and more like the problem is me. I haven't had a chance to check my tire pressure yet, I will try this afternoon.
@Siber Express congrats to you especially. Never heard of a 4.0 getting mileage that high. I have run a whole tank on the interstate on stock rubber and got just under 27. Did anything change to the 4.0 in 2010? You say "before my tune" So this was on the stock tune? what about after?
I know i need an alignment and I'm running stock auto tranny fluid at 85K but I wouldn't think that would account for any MPG loss, <1 MPG I would think.
Thank you all for your replies!

Wait, you have fuel mileage issues and you haven't checked your tire pressure but DID do a ton of other expensive maintenance? Weird...
Have you checked to see if your brakes are dragging? Bad wheel bearing? Alignment issues? Any of those will attribute to rolling resistance. Air intake clear?...

Mileage went up over 2 MPG just changing the muffler right when I first got it.
I wish my 13 got the mileage the 10 got, but it is about a mile per gallon under what the average was on it

So,
New struts & shocks,
New strut mounts,
New LCAs,
Two Alignments,
Fresh Autolite plugs,
AM 93 tune,
Last tank of gas...
15 MGP
Its 90% city but that is still too low. I guess this is the new norm

I would get about 18 on my 07 v6 pp with cai, 91 tune, and 18 inch gt wheels off a 2011.
On my 2013, Highway ive averaged at 24, and city between 17 and 19, with 19 inch wheels. Can't really complain tho for what you're getting out of it
