This is an idea I got off of the "Gas Prices and how they set you back" thread. I thought it'd be interesting to get the numbers on different gas stations, different levels of octane, and the overall efficiency of the gas. Over the course of time, I'll be recording all this info in this first part to this thread. If anyone else wants to do something like this, it'd be interesting to compare results.

EPA Says: Auto 2.4L = 19 city miles, 26 highway miles
EPA: Manual 2.4L = 21 city, 29 highway
EPA: Auto 3.0L = 18 city, 25 highway
EPA: Manual 3.0L = 18 city, 26 highway

Keep in mind, variables like driving style (lead foot, etc), tire pressure, and mods to the car play into this as well. My main goal is to see if 1) the EPA thing is fairly correct and 2) See if mods to our platform have an adverse affect on gas mileage.

My personal best was 38.5 mpg's in my 2.4. 65mph, all highway. Cruise control most of the way. 485 or so miles on the odometer.

Personally, I have found 87 octane to be the best. 93 didnt do anything for me except make my wallet $2 lighter.

In stock trim, I was getting about 29 mpg on 87 octane. A few months ago, while on a trip I measured 26 mpg on 93 octane. Not too bad for a 350 hp Stratus (IMG:style_emoticons/default/smile.gif)
