Hemi Gas Mileage?
 
For those of you with the Hemi, what kind of gas mileage are you getting? i hear you can get better than what has been advertised. With gas at $3.25 i sure hope so.

I drive pretty hard (70-80mph most of the time) and remote start alot, so I have been seeing around 14 overall. However, I would seem that when driving normally it averages around 18-20. That said, I bought the hemi for the power and an SUV for the capability. If MPG was what I cared about I would have bought a smart car or something.

Right at 15 with 75% city and 25% hiway combo calculated. Haven't recorded any hiway only milage.

I am using the remote starter a lot too because of the cold. Around town I am average 14-15mpg. When I fill it up and take a trip I get 21-23mpg on the highway. I averaged 21.5mpg on my last trip going into a 10-15mph headwind with an average speed of 72mph.

I do have to say that if you want that kind of mileage you can't use the cruise control. With the cruise set at 75mph I average around 19mpg. With the cruise off I drive like there is an egg between my foot and the accelerator. Most of the time, even on inclines it holds 4cylinder mode. I find that if I am doing 75 at the bottom of a hill I can let my speed drop to 68mph or 70mph on an incline (by simply holding the gas constant). Once I get to the top of the hill it builds speed back up nicely and I just let it go with it on a downhill run.

Getting between 15-16 mpg with a combination of suburban (50%), highway (30%) and city (20%) driving. Getting better with warmer temperatures. Over 5500 miles in two months.

I dont know how people get such "good" mileage. I average 11-13. 13 being with some parkway driving. I know highway only I can get 19 or more using cruise control. But city, stop/go and remote start seem to kill the MPG and Im generally near 12. and no I don't WOT, I even try to drive to get better gas mileage, go the speed limit, etc.. o well its a hemi. It would just be nice to get near people who average 15 or so

14 to 15 so far, mostly city driving. I've got about 2,400 miles on the odometer and will soon be taking an 1,200 mile road trip,mostly interstate.
I'll report on my results. It helps if you monitor the "fuel economy" thingy.

Yea Im also heading on a 500 mile trip tomorrow and then return 500 in a week or two, I'll be sure to fill up tomorrow before and reset the MPG for the highway. Hope to average 20 or better!

I average 11-13 mpg depending on how much highway driving I do. I do not know how people are averaging 15 and up? I try hard to drive and keep that Eco light on.

Just a thought but, have you tried changing to a different brand of gas? Gasoline retailers are allowed to put a certain amount of ethanol into the gas, and this may vary between retailers. (An off-brand might even cheat and put more ethanol in.) That would hurt your gas mileage.

I use Hess, which is a large company on Long Island, and I know in NY the gas can contain up to 10% in ethanol but I thought that is national wide standard pretty much? I dont go to no name people though as you never know where the gas really comes from or how old it is.. Good thought though hmmm
