    Default What's your MPG? #2

    Now that I've had my 2010 Traverse for a few weeks, I'm pretty much settled in that I'm going to get about 24 MPG freeway going between 60 and 65 with cruise control on. City is much different, depends on what type of stop-and-go traffic I'm in, but overall I'm right about 16 MPG total city and highway.

    I'll repost my mileage since it has changed a bit.
    Highway: Best: 21, Worst: 12, Normal: 16-18
    City: Best: 12, Worst: 6, Normal:10-12
    Combined: Best: 18, Worst: 12, Normal: 14-16
    Factory EPA estimates: Highway: 16, City: 12, Combined: 14

    So I'm running close to factory numbers with 198,000+ miles.

    1996 Chevy Tahoe LT 5.7L V8 4X4 205,000+ miles. Built proudly at Janesville Assembly in Janesville, Wisconsin
    Basic mods: Lights all over, bunch of electrical work, and a couple cooling mods.

    Check out my other mods in My Garage:

    On the winter mix I'm running ~13.8 city and ~16 hwy. I get about ~14mpg combined since most of my driving is city. Factory numbers for this truck are 15-17mpg, so I'm pretty pleased to be running only 1mpg under par given the age of the truck and my mods.

    2012 Duramax
    Getting about 12-14 city
    16-21 highway depending on speed. 70mph gets around 20 consistent while anything over drops it quick.
    Towed 12,000lbs @ 85mph Friday night for 100 miles and got around 12 mpg from Central to Southern KY.

    Thinking about a programmer to try to get the non towing mpgs up a lil more. (is it worth it?)

    I just tallied it all up. Since my engine swap, I averaged 13.5mpg over 1500 miles. That was some highway, some city, and some dirt and 4x time thrown in. Huge improvement over my last setup!!
