So is the heat affecting my gas mileage or is it that i have my windows rolled up? hotter air means less dense air, right? Less dense air means less fuel, right? It has been about 10-15 degrees warmer today than usual. my gas mileage has been a LOT better today.
My driving has been the same. I drive like an old man. I usually drive with all four windows down and the sunroof back and the A/C off, not even the blower on. When I usually drive down the highway, I can't even get to 27mpg. I could reset the gauge and it will immediately even out to 26.8 mpg. The temp is usually around 75 to 80... 82 at the highest.
Today, it's 94 degrees. I had all four windows up and the sunroof closed and the A/C on FULL blast. I reset the mpg gauge (the running average not the current "what you would be making if you drove how you're currently driving"). I make a turn at a traffic light, hit one more traffic light before I drive 10 minutes straight at 55-60 mph (no cruise control). I started off at 38 mpg but assumed it'd even out to 26.8 mpg again. 5 minutes later I'm at 33 mpg. I bump up to 65 mph for 3-5 more minutes and never go lower than 30 mpg. After 10 minutes of no slowing down, my average was actually exactly 30.0 mpg.
The fact that I AVERAGED 30 mpg when I can usually never get better than 26.8. Before this, honestly, I've TRIED to get better and I was able to get 27.1 once with a bit of coasting.
What I don't get is that the A/C was on all the way... I thought A/C hurt the mileage? Did the heat affect it at all? Was it mostly my windows being up?

Google won't search for Chuck Norris because it knows you don't find Chuck Norris, he finds you.
lots of drag when the windows are down, you can actually save gas using the a/c.
MythBusters- Gotta love 'em, they also proved that leaving your trucks tailgate up allowed air to flow easier over the truck creating less drag- would of never thought that would be the case.

anything that helps your engine breathe easier helps gas milage. Better exhaust, turbo. I don't know about superchargers since they are belt driven, they suck horsepower, and gas.

Mod List. Um WAY too many to fit on here. But the engine can handle about 800HP
I am getting awesome gas mileage now that I am riding my bicycle to work. I am actually getting better mileage with my car cause I am not making little 2.5 mile trips 4 times a day, I am only driving on the across town trips.
i was wathcing this show on Discovery Channel, not MythBusters. it was a car show with some Brit. I liked that show.... Did you know an Apache Heli can't get a missle lock on a Lotus Elise when confined to a certain area?..... Anyway, it said that driveing with your windows done, it uses up to 33% more gas than with them up, also, braking, using any extra electronics, and AC will cut into your gas. they got like 800 miles out of an Audi diesel. it was cool
