Have a 2017 Ram 3500 CTD with 373 gears. Has about 500 miles on it. Will it get better MPG when broken in. Tripmeter says average 15 Mpg. Thanks. PS. IT sure is sweet. All smiles
our 05 duramax was showing the exact mileage as the math until 2009 when the speedometer decided to go insane. After the repair the numbers were way off from the math numbers so after 2 flashes. Going to Casa Grande from Wa st. 2 years ago the dic read 11.4 and the math was 11.18. Close enough. Like the post above tow and enjoy the trip. The mileage gets less important.
