Sports car is turbocharged. Runs over 190 and gets 28 mph on the highway if you stay out of the boost. Stay in the boost and she will empty the fuel tank in 100 miles.
I was wondering how fast some of yal drive and your fuel milage thanks. Answer! I go 60 MPH if i got time for the next load. If i got time to pull two short loads before the Port closes at 4:30 pm, i hustle and move that Freightshaker! but 60 thats my target speed. Once i do a overheard and replace all the fuel injectors, i concentrate on MPG.
Its mostly the weight of the load, terain, weather and wind that affects the outcome of your MPG. I've found that speed is not much of a factor as log as you are maintaing your speed.
