My Ram is new, about 1,200 miles and today I did the first real hwy trip. I filled it at 7-11 with 87 octane and got on the highway. I drove 175 miles, all interstate at about 75 mph, a little less for a while and little more for a while, never over 80 mph. We got to our destination, did about 5 miles in town and headed back home. About 30 miles from home, the gas light comes on. I found a station and fill it up. 23.62 gallons and 335.5 miles equals 14.2 mpg! My window sticker says 19! How could it be so bad? I should claim fraud by Dodge!
I used cruise control almost exclusively, never flooring it. No A/C on. WTF?

the more miles you get on your motor the better your mileage would get, and I think most people recommend running the 89 octane in the hemi's. Don't quote me on it as Im not sure from experience as Im runnin a diesel, but from almost everyone Ive heard from once you start adding some miles it will get better.
