It did get down to 1 F .... MPG down may be due to temp tire pressure down.....?

Tire pressure is always a good thing to check after major temp change. With the cold temps milage will still suffer. It will be better when warmth comes back.

Pumped tires up to 35 from 30....temps this week 5-21 F....2.4 auto...mpg improved to 24. I think the wife is using that remote start thing a lot & letting it idle to warm up before she leaves work...

One other thing that may help a tad is to not leave defrost on when not needed as A/C compressor is turned on while using it. My milage has been on steady decline since cold weather made an appearance here in northeast

Married 36 years (since age 18), suspect she'd forgive me for this one insensitive statement....retirement from Fed = 12.5 more weeks!!!! 31 years VA, 6 years USNAR, 36 married, 27 father, 17 school = 117 years, no wonder I feel old!!!

I assume you mean K& N filter. I don't have any personal experiance with them, but I checked their website and see nothing there thats indicates their air filter increases economy (other then a clean filter does better then a dirty one). There is no shortage of claims from people who claim better economy though (perhaps they only check after replacing the dirty one with brand new shiny new one without checking similar MPF (miles per filter)

Better MPG by steveandbelind

Is there a way to get any better MPG that someone knows of? I just bought my 07 last Saturday, and other than it showing most the time about 23.8 city, and around 31 or so highway, I haven't really had a chance to see what it really gets. I will be taking a 1000 mile trip probably tomorrow, so I WILL find out. I seen on Ebay that there are several things that they say helps out on mpg, like Turbnado, which is just a piece of metal that slips in the air intake hose, supposedly creating a vortex. I put the original Turbinator in my Explorer, and didn't really monitor it. Don't really think that it did much, but not sure.
