Every two weeks or so, the Ram rolled into a gas station and gulped. Twenty-nine full tanks later, the truth: the Ram averaged 16.40 miles per gallon across nine months of mixed-use driving. That's 18% below the EPA combined sticker — in line with what a half-ton actually does in mixed suburban + winter use, not the lab number.
Each dot is one tank. X-axis: average outside-air temperature during that tank. Y-axis: measured MPG. The Ram gets meaningfully thirstier when the mercury drops.
