8.5 mpg local and 10.8 mpg at 75 mph?

Old set up:
Z tube.
K&N round air filter jammed into stock air filter box.

New set up:
Z tube.
UTR CF air filter.
Deleted stock air filter box.

After changing my dirt covered K&M air filter back to my CF air filter. My monitors been reading 10.8 mpg at 75 mph. When I had the K& N installed I would get in between 14-18 mpg. (Yes, I know most speed limit is 65 but sometime I just canít help myself) Then on local streets with the new filter itís reading 8.5 mpg when I use to get around 12.-14 mpg.
I can feel a better throttle response and the sound is much deeper but 8.5-10.8 mpg? What went wrong? P.S. Iím driving it just like I did when I had the K&N.

Re: 8.5 mpg local and 10.8 mpg at 75 mph?

My engine is all stock except a K&N filter, I get 14 mpg average (measured by entering gas fill-ups into aCar app) I occasionally get higher when I drive highway, but I have a lot of hills in my local drive which brings my mpg down.

Ive been thinking about some of the engine mods listed here, but I don't want to lose more mpg

06 FX35 tech,nav,sport.
Installed: Led lamps in parking lights, curt tow hitch, halo ring fog lamps, K&N air filter.
ToDo: Fix DRL mod, Ipod/stream, Tow lighting harness...

Re: 8.5 mpg local and 10.8 mpg at 75 mph?

I used to let my 2006 calculate MPG over 1000's of miles (rarely reset it) and i never got MPG as low as you both are talking about.

18.3 in mixed driving over a few thousand miles. Repeatedly... for years.

Right now i'm getting 19.7 in my 2010 - also mixed driving, some highway, some local.

Re: 8.5 mpg local and 10.8 mpg at 75 mph?

By all the feedback from everyone, Iím guessing it depends on the location as well. As for me, Iíve been driving pretty much over the same routes that I did when I had my old filter. Couple of days have passed since I installed the new filter and didnít see any improvements regarding the mpg, so I gutted the front air flow portion, power duct, and front portion of the air filter box and wxtended a 2.5 inch tube into the back portion of the air filter box to have it act a heat shield. The set up looks so ghetto but the mpg has increased to 14.8-18.4. Once I see it jump to 21.8. I know I should just change it to a different intake system but with what I'm getting now. I'm very happy. I just have to make sure I never show off my engine bay. LOL
