    What are fake shift, NICE-ON, DWL, DWB? Can someone explain these?

    Also did anyone see my question about the electronics in my car? Could those be affecting anything?

    Thanks for all the help so far guys.

    The current draw of the stereo is going to depend on the volume that you're playing the music, but its unlikely that its going to draw as much as, say, A/C or the headlights even when cranked. But it would act in the same way, and rob you of some FE to some extent.

    The added weight is also going to effect the performance, and I actually removed my sub box to save the 100lbs or whatever it was.

    But even with both of those factors combined you should still be getting better than what you're getting IMO

    BTW... You can usually turn on the car in Neutral as well as Park.
    So while coasting you can turn it on in Neutral.

    HOWEVER! Since you have a automatic tranny you should NOT Turn off the car while coasting.

    There is usually a lubricating pump in the tranny that only works while the ICE is on.
    So just pop it in neutral to coast and leave the engine on.

    Fake shift - I do believe this is a technique developed for use with the Ford Escape Hybrid. But, I think it involves getting up to speed and then releasing the gas pedal slightly which will sometimes cause the automatic transmission to shift up, say, from 3rd to 4th. Generally speaking, the higher the gear the better the gas mileage. This is why manual transmission is highly preferred for gas mileage - you can always force the car to operate in whatever gear you choose whenever you want.

    NICE-On (neutral internal combustion engine - On) - This is basically when you coast in neutral with the engine running. This method allows for longer coasting compared to coasting in gear (or "D" for automatics.) This is also the preferred method for P&G with an automatic transmission due to the fact that it won't harm your transmission like a FAS would. (fyi, FAS is coasting in neutral with the engine OFF - generally speaking, don't do this in an auto)

    DWL (driving with load) - It means you keep the gas pedal in one place starting at the bottom of a hill and keep it there as you go up the hill and then back down. Obviously your speed will drop as you reach the top of the hill but it's more efficient to drive over hills this way than to maintian speed all the way over. Gravity will help you get back up to speed on the way back down the hill.

    DWB (driving without brakes) - You pretend you have no brakes. It means you now need to start coasting waaaay before the point where you want to eventually be stopped. For example, a stop sign is ahead - instead of giving the car gas up to the stop sign and slamming on the brakes right before it (wasting gas) you alternatively let the car slow itself down and start coasting down to the stop sign from very far away. Obviously this is difficult to do in traffic sometimes but if you get the chance, use it! Rule of thumb, if your hitting the brakes, your wasting gas - you're "undoing" the gas you gave the car.

    Hope that helps. Don't give up. You will save gas.:)

    Remember: Idling (not shutting off) your engine eg. at a traffic light dramatically REDUCES your mileage. Get used to shut off the engine by going into NEUTRAL during the deceleration phase and turn the engine off immediately when stopping. Watch cross traffic in order to be ready for engine start. Do not hit the accelerator when restarting the engine. In city traffic, at least every 7th gallon is being unnecessarily used during traffic stops!
    1 - 2 - 3 - 4 - SAVE (automobile engine start consumes as much fuel as 5 seconds idling!!!)
    Search for topic 'idling stop' in GOOGLE to get more information.

    Savefuel he shouldn't coast with ICE off.
    Its an auto.

    I think what he meant by "turn the engine off immediately when stopping" was "turn off the engine as soon as you are stopped".

    During a typical inner city drive, 15% of the total fuel is burned at standstill!!!
    No kidding! If your vehicle engine is not turned off at (traffic) stops you just lower your mileage significantly.
    In a study together with TOYOTA, ECCJ (Energy Conservation Center of Japan) recently
    proved that starting a 2000cc engine properly (without hitting the accelerator during the starting process) consumes the amount of fuel equal to < 5 seconds of idling.
    So, if You are approaching a traffic stop: Go to NEUTRAL and shut off your vehicle engine!
    Watch cross traffic in order to be ready for engine start in time.
    Each 5 minutes of unnecessary idling reduces your fuel range by one mile!!!

    Ah I see...
    Just make sure you arent going faster than 20 mph when you turn it off.
    Any faster may hurt the tranny while with the pump off.

    I'm not an expert, but i'm pretty sure you can cut the engine while rolling to a stop at less than 10mph with no harm, but I wouldn't go any higher than that because it could destroy stuff. I've never started my car when it's moving, but I don't see why I couldn't because I usually stay in and restart in N when stopped at a stop light (since it's closer to the D than P).

    edit: whoops, seems I haven't refreshed this thread in a while. or maybe i just missed the other 2 pages...

    Took a short road trip (186 miles), got gas cause it was cheap ($3.87), and bam, 28.3 MPG. So then I had a short 50 mile drive home on the highway. I tried my best to coast and stuff and use less A/C, and then I filled up again when I got home to see what kind of mileage I got strictly on the highway - 40 MPG. I'm so happy right now!

    I guess it got pushed back
    Nice Mileage!

    40 MPG is not bad at all for your car.
    Though I am right behind you with my RAV4 36ish ^^

    Yeah, now it's time for me to get my average MPG up.

    I think what might've been killing my city mileage was the fact that I mainly drive to and from work (2.2 miles) everyday. There are 2 routes, each one includes at least 2 red lights though (no way around hitting them). On top of that, the lights are too short/hard to time and turn my engine off. So all these things combined are probably what kills my day-to-day city mileage.

    Real quick, how much does having your headlights on 24/7 affect FE?

    If you FAS, that will cause a 1-2mpg hit since the alternator may work overtime due to the battery being low.

    even if you dont fas, it still will have an effect, but it would be a bit less. this would be offset by the benefit of the fAs tho.

    How do I do a fas in a 5 spd automatic?

    You don't its force auto stop which means you basically turn off the engine.

    On an auto That's bad for your tranny.
