So, when I am in Huntsville for breaks from school, I can get 24 MPG city from my Camaro (which is pretty awesome). When I'm in Greenville, for school, it drops like a brick! I get 18.7 MPG city. I don't drive any different, nothing on my car is broken, and I've added an SLP air lid.

What in the world would account for losing a little over 5 MPG?

 

Hillier terrain (harder hill climbs) perhaps?

 

Different brands of gas? More ethanol in it? I knowo I lose up to 2 mpg just going from 93 to 89 octane.

 

Oh, I bet I know what it is. They embed high powered magnets into the street, so it drags your car down, and lowers your mpg. It's a conspiracy to get the local gas stations to sell more gas.

 

^man did you burn out at woodstock? or in your room listening to zeppelin on a album?

 

its the traffic in greenville, woodruff rd, pelum, haywood, and pleasntburg are redicioulous. not to mention the construction on 385, traffic SUCKS here

 

I have a feeling there's a joke in there somewhere!
Seriously tho Art, you would need to log your miles, and record what kind of driving/how long you're sitting still. You probably know better than us as to what the difference may be, but you might not know you might know, you know?

 

69, I sure hope it's not the magnets! Next they'll be following me in black helicopters too...

BC, I usually end up driving down Wade Hampton. While the traffic on it isn't terrible, the timing of the lights is. I always have just enough time to get up to speed before I get to stop again. :/

I kinda figured it was probably just Greenville being ridiculous, but I'm glad to know there's not some crazy thing gone wrong with my car.

 

ya i hear you about wade hampton, but its the stop and go traffic thats killing your fuel economy.

 

Saw PennDot doing that when they redid our city's main highway. I didn't understand it at first as to why they add these huge magnets, but I wasn't about to question PennDot and all it's intelligence. Makes perfect sense though, the car did seem a little bit slower than usual.

Quality of gas can be a big factor. I normally buy from Sunoco, but recently have been getting from GetGo instead since it's about $.05 cheaper for 93. I've noticed ~1-1.5 mpg difference. If you use Sheetz, I recommend you start going some where else. Sheetz quality sucks. Also, never ever buy gas from a station that has the tanker filling the underground tanks up, that is a no no.
