i have read with interest the notes about the ram 1500 gas mileage. we just purchased one last week. our first tankful of 385 miles yielded 17.1 mpg, a combination of city/hwy. considering the truck is not broken in yet, i am more than satisfied. also this mileage was with regular 87 octane. i refilled it with plus89 octane to see if there is any difference.
