What are your tricks?

These are my tricks and things I do currently:

-Coast as much as possible (DFCO)
-Drive 55MPH on the highway
-Coast to stop signs and lights
-Slowly and smoothly accelerate during starts
-No A/C or heater use yet (waiting till winter)
-Windows cracked open about an inch to prevent fogging
-Monitor fuel consumption religiously
-Try to drive as close to 50MPH as possible when not on highway (within reason)
-Turn car off as soon as I come to my destination, then do everything else (put in park, put windows up, etc.)
-Let car idle only for 30 seconds to warm up, otherwise none

I can't think of anything else. Let's get this FE section bumpin'!

In the real world, it doesn't take more than ~1.5MPG per tank.

When you think about it, it's not that much of a big expense for being sweaty all the time (At least for me, living under the equatorial heat. That, and I sweat alot.). Not for me anyway. I guess it comes down to everyone's individual priority.

O.o

Why would you have the AC on full blast and the windows down?

Same as dvlnblkdrs, by myself i have the windows down and ac on, so i can listen to my music full blast and the wind. When you get red lights or such it gets hot, so u need the ac on till you start moving.

Windows down + A/C.................... Is there a gas leak or something in your car? That's the dumbest thing I've ever heard of in my life. Flame the crap out of me for being rude, I deserve it. But seriously... I'm speechless.

And no, it hasn't been "debunked" that A/C doesn't affect MPG. Ask the scangaugers -- it does hurt fuel economy. What has been debunked was having your windows wide open on the highway VS A/C. Windows down is better.

This post is about what you do to help your fuel economy -- not blatantly disregard it... Let's get it back on topic.

I either do one or the other... There are virtually no stops on the way from home to college, but there's usually REALLY heavy traffic so I'm usually idling-stopping-and-going all the time.
I use the AC when traffic sucks, windows down and full blast metal (on stock speakers ) when I can freely glide across the city streets.

Where I am, I have a pretty clean shot to where ever I need to go. I'm on back roads where the speed limit is around 40-50mph, then I'm on the highway where I do 55mph. Probably only 10-20% of my commutes to places are in traffic. =]

the car uses 7 seconds worth of gas startng. so if the light is red for longer than 7 seconds its worth shutting the car off.. if its quick its not worth it

That's a cool fact/figure. I would shut my car off at lights, but I don't want to hold people up behind me. I like to pseudo-hypermile, I do as much as I can without interferring with other peoples commute.

you can watch the other lights to see when yours is going to change. and turn the key to start the car when the light before yours turns yellow..

seems to work fine for me :)

Well, back on topic. Here's what I do.
- Crack my windows down whenever I'm not stuck in heavy traffic.
- Try to use DFCO as much as possible
- Keep my tire pressure at max rated pressure.
- Pulse and glide like hell.
- Avoid rabbit starts and stops.
- Coasting. To stops, to lights, to traffic.
- Turn the car off whenever I stop to do anything. (Except stop lights, I tend to get distracted at lights, so whenever I turn it off I take like 3-4 seconds to get moving and piss everyone off).

All that and I'm getting the shitty mileage on my sig.... In a 1.3

I forgot about that, upping the tire pressure. I figure during the winter I'll want a nice wide footprint, but come summer they're gonna be right at 44psi.

I'm also going to switch to 5W-20 Amsoil full synthetic at 5K. But I think I remember someone saying they don't make it, they only make a 0W-20 which is the same thing apparently to Amsoil -- in which case, I'll just use that.

All I do is coast to red lights, and stick to the speed limits. I also have the tires(Stock Eagles) at 44 psi.

I am experimenting with 0w-30 Mobil1. The only difference I've seen is that the engine warms up quicker.

As for the A/C. Looking at my scangauge, turning on the A/C will increase the gallons per hour slightly.
