5.3 11,000k+, stop and go around town 16.2-17.5, best mpg has been 19.4 pretty much freeway at 70- 75 mph. Thats per my mileage readout on the computer which I've checked manually and is within .1-.2 mpg.

Best was 23 highway. 5.3 Corsa cold air definitely added a mile or two

Curious what everyone is getting for gas mileage on their Trail Boss? I have the 4.3L V6 and only have 4,500 miles on it. I'm getting 15.6mpg. Don't know if this is typical or if it will continue to get a bit better with more miles under it's belt?

I have a non-DFM 5.3 and am getting between 18 mpg around town and 20 mpg highway...'22 LT refresh
