Drove from Seattle to Olympia then to Tacoma and around Tacoma and back to Seattle (130 miles of mixed city/hwy). Averaged 13.8 on the computer. This is the best I've achieved in the two years owning my Ram Hemi.

06 Ram 1500 5.7 with 3.55's. Averaging about 16-17 MPG, with a mix of highway and city. My overhead vs hand calculating is actually within .5 or less (sometimes I wonder how accurate the gas pumps are) so I just trust the overhead anymore being they are pretty close.

2004, 2500 Hemi, QC. Usually around 12.5 -13 around town. Just calculated 15.5 with mixed city and a 3 hour highway trip. Ill take that anyday!!
Clean your TB, use 89 gas, dont get a muffler like I did with my flowmaster because it makes your foot heavy for some reason lol, keep all fluids up to check.
Oh and spark plugs are huge. My truck could hardly make it up the hills when the spark plugs were bad. I felt so much better after changing them. They are very important to a well running engine

That must be 95% highway 5% city.
I filled up, and I only did city on this tank of 89, and I got 9 MPG.
Highway I get 21MPG, but I gotta make sure my tires are at 37ish PSI, and hold the speed on cruise at no more than 60 MPH. 65 MPH got me 16 MPG, because MDS was kicking all 8 cylinders on more often.
Tire pressure is critical in the MDS Hemis. Low pressure will cause all 8 cylinders to kick on more often because of the extra rolling resistance on the highway.

I don't really know how much I'm getting I have a feeling the overhead reading is off with my lift and tires. I'd assume its about 13/16 city/highway. Imo the big tank makes up for it though cuz I have to fill up every week and 3 days just about so I'm not complaining

Unless your "average" is all highway I'm gonna have to say you're exaggerating quite a bit. I've never seen a 4x4 QCSB average that, hell I've barely seen 2WD RCSB that do.
