Need recommendation for a Carb for better MPG!
The only way I can think of in order to get good gas mileage is to do a complete tune up, dial in the carburetor and ignition system, proper size tires and tire inflation. For highway mileage, a good set of gears and a overdrive transmission. And use the cruise control if you have one if not driving 5-10 mph under the speed limit helps. The 2010 Colorado I had got the best mileage for a pickup truck, it was a extended cab wheel drive, with the cruise control set at 65 mph and the ac on I got 27 mpg highway, that's something that a mopar won't get
