I avg around 13 with mostly city/mixed hwy. This week I've had an 80 mile round
trip commute w/o much traffic and I'm avg about 19 for the week. If it's all freeway
I can get up to 23-24, better if I slowed down a little.
I used to get about 16mpg before I installed my GT Haus cat-back system with a mix of city and highway driving. I short shifted, backed out of the gas early, coasted to stop signs, the works. Now I shift late, cruise aroumd one gear lower than before, and average less than 12mpg. If it helps, my 32,000 lb diesel RV gets 10.5mpg, at least its not THAT bad..
i average 18.3 overall. i drive mine almost everyday, mostly on back roads to work (32 miles one way). i drive it like i want, turning the tires and hitting at least 100 most days. so i think i'm doing pretty good.
HA....if you care about fuel mileage you won't buy the SRT8. These cars do get ok mpg IF you keep your foot out of it.
Driving a 6spd SRT8 and keeping your foot out of it IS NOT, I'll say that again, IS NOT possible to do.
That being said I've gotten a best of 24 on highway trips and a worst of 11 in town with light to light bursts. I usually average about 15-17. I really don't pay much attention to it as it was of no concern when I purchased her. The last two vehicles I owned were trucks, one of which a lifted 08 Ram 2500 Power Wagon w/ 37" mud tires and a 900lb custom front bumper getting a wopping 8.5 in town and 16 highway.
I like to have fun and don't really care about what it takes to get there as long as I don't go broke and have a buffer
On a serious note, keep your right leg controlled and don't cruise in 6th (has been discussed to be a pretty pointless gear) unless your cruising the autobahn(my dream with this car). Shift between 2700-3000rpm. Intake, 180 thermostat and free flowing exhaust would help but then once you hear the raw hemi goodness, the controlling of the right foot goes back out the window.
Bottom line......get the SRT8 anyway and you won't regret it. I went from an RT to an SRT and I'm glad I did
Wow good stuff guys. Especially that Fuelly website. Great evidence. It seems to be the average amongst you all is about 15-17 per tank. Not horrible, but I am getting that now in my Frontier, and it drives me nuts to fill it up so often, and it's regular fuel with a cheap @$$ payment. I think I should ask this same question again for the R/T folks, just to compare apples to oranges.
