How? Did you swap your engine with a VW or something? I've also found that only driving downhill helps a lot with mileage......

I haven't really noticed a big change in what the DIC says i'm averaging, but I've noticed a big drop in the range in the past few months. I've only had my Yukon for about 9 months and when I got it, with a full tank on the way home from the dealer my range was showing over 500 miles to empty. Lately I've noticed after fillups it will show in the between 380-410 range. I replaced a set of worn plugs and upgraded to MSD wires and ran a Lucas fuel treatment through on a recent road trip, and not much change. I did air up the tires this past weekend and immediately increased my range by 30 miles. I wish I could get my mileage back up to where it was, it's driving me crazy with $3 a gallon gas prices at christmas time.
