What fuel economy are u getting? Style of driving and Fuel Octane used?

My first tank resulted in about 34 Mpg On Unknown fuel octane/brand with mountain roads and about 200 miles of freeway driving...

Ill be keeping close tabs on the fuel economy as My wife has a steady Jog to work and back that will stack up quite a few miles in no time at all/try to narrow down if Octane matters and what brand it likes

I've kept a spreadsheet on my Challenger since day 1. Overall average with it is around 20.5. Low of 12.5 and a high of 27. I wouldn't know how to act with 30 something plus!

Haha jkelly16. You must be like me. I cant keep my foot out of the throttle long enough to get to 25. This is a fun car to drive!

I started taking note of fuel economy this weekend. I filled up and drove a mix of highway and slow traffic for a few hours. After half a tank I went 250 miles. After about an hour on the highway I reset the mpg readout and it went up to 43-44 mpg. I did not touch it for the next day or so and it reads 32.8 mpg. I now have over 500 miles on the car and am very happy with the mileage. That is the main reason we got her.

I'm glad this thread is here, as this is the main reason I bought my Dart. I averaged about 27mpg on my first commute to work this am. I haven't had a chance to get a good stretch on the highway yet, but I'm expecting to see 35+ mpg. As far as octane is 87 regular ok? Do these 1.4l turbos really need premium?

Our 2.0 is averaging about 25-27 in town and 34 on the highway.
My Challenger only averages about 16-18 city and 27 highway.

Currently I'm getting around 32mpg City and 35-37 highway. But, I'm a very careful driver. Very rarely do I shift past 3500rpm, unless I'm bored. Then I like to play a bit... but even still. I have yet to see less than 27 avg.

Oh, and I use 91. Only. No other option.

My first tank I averaged 29.85 mpg in a mix of 60/40 city/hwy driving to and from work. The EVIC read 31.9 mpg avg at the time I filled up, so the computer is a little generous in calculating fuel economy, which has always been my experience with Chrysler vehicles. I have decided to use premium instead of regular even though the manual says 87 is ok...it's only an extra $2 or so per tank.

We have been averaging 32+ combined city and highway. I am very pleased with the mileage. It's in the high 20's at times. In bumper to bumper traffic and low 40's on the highway with A/C. On.
