Re: Realistic OBS fuel milage
Since your cali has split shots(correct?) our trucks are somewhat similar, but i have stock suspension and 285's. When i went down to Unlimited Diesel it was 2.5 hours on back-roads running 50-60, and playing a little if i got bored. I averaged between 19-20 mpg's there. Coming home i ran on the highway from 70-90mph in rush hour traffic at times, and got 16.5. City driving i've seen it as low as 13.5 and as high as 17ish with my AD's.
Keep in mind i have an injector not firing, leaky up-pipe gasket causing the turbo to not lite until 2k RPM's, and a tranny that was going out. And i'm a teenager, so i don't drive it easy all the time.
