the only thing i did not know was that starting up a car = 1 minute of idle. I usually turn the car off if theres a 30 sec wait, but now i leave it on if its less than a minute.

Here is the article, since he wants us to see it. The thread was cross posted in several forums. One thread was left open, the one in Accord Forum.
-------------------------------

Those were the good ol’ days, when gas was like oxygen, a necessity that fit nice and comfortably into our daily lives, never causing trouble for anyone. However amidst all the ruckus in our world today, the gas prices have nearly doubled since 1990, and that’s enough to get us off our bottoms and into famine-mode.

If you’re like most people, then you will have the following things in common. Firstly, you do not drive a hybrid car, and second your wallet can feel pain.

However, the public transportation system in America is as heartbreaking as baby seagulls dying out of the sky and can only take you from point B to point S. This makes cars a necessity and not having one is just as bad as not having any legs.

So what can you do to save gas and revive your wallet? There are tips here and there, but not only are they vague and obvious, they also conflict with one another. So this article, will attempt to cover every angle of the fuel-efficient lifestyle based on research and experiment as well as tackle common myths, and I can guarantee that following these tips can greatly increase your mileage.

Preparation

So before we delve into the economic views on the road, let’s view the economic views before the trip. These can make large differences in your results. The most basic is of course, items that deal with common sense, such as planning ahead. Knowing the entirety of your path helps you to avoid unnecessary trips and thus giving you more worthwhile miles on your car. But we all know that, so onto something a bit more technical.

One of the biggest things to stress is weight loss, most Americans are obese and so are their vehicles. Most of our cars slowly become our closets and storage bins, and over time it ends up becoming one big pointless stupid heap of junk. The heavier a car is, the more fuel it will require to get the car moving. Not only that, it will also require more fuel and braking power to bring the car to a halt. So remove any unnecessary junk from your car. And if that’s not motivating enough, then just focus on the fact that you are paying money simply to haul this needless luggage around. If you have roadside assistance, you can even consider ditching your spare tire, although this is one move that I would not recommend.

And while we’re on tires…tire pressure also plays a large role in mileage savings. Most of the time spent driving is spent cruising down the road without a care in the world. But you should care, because tires filled up to a proper 35-40 psi will reduce road drag, and thus, allow you to cruise farther and longer before having to put your foot back down on the pedal again.

So let’s say you’re done with all of these nose-picking chores, you can now get on with your driving, but this is where you’ll need your Bruce Lee catlike reflexes.

Green Light


First off, you can’t forget that oxygen is a real thing. It may be immensely small, but it still exists and can and will get in your way. Aerodynamics is the biggest thing that racecar companies spend their research and designing on, so it must be fairly important.

At any speed over 50mph, driving with the windows down and sunroof open will add a ton of drag on your car. Taking in that cool relaxing breeze will actually decrease your mileage efficiency by 5%. Also having large team or nation flags hideously mounted on your vehicle will also cause drag and require more fuel to keep your car going.

All electronics will also hurt your fuel economy such as defrosters, heated seats, the heater, and cruise control. However, don’t forget to keep safety in mind, if you need the defrosters, use them. Luckily, the radio doesn’t use much electricity at all, so it is fine to use it and relax your mind from the stress due to all the concentration required. However, be warned, that surveys show that fast aggressive music leads to an iron foot.

But even worse, worse than all of the electronics combined is the air-conditioning. The A/C system hurts your mileage by a whopping 20%. So, if you’re driving a tyical Honda Civic and you’re doing 36 mpg, turn on the air conditioning and you’ll be doing 30!

It is a common idea that staying at or below 55 mph is the best for your car. Generally speaking, that is true, however, only on a large average. Every car is different. Some of the cars I tested do best at 65 mph, while others at 50 mph. You’re going to have to find your mark on that one. But I’ll tell you right now, it won’t be 100.

While sitting at a red light, put your car into neutral and take your foot off the brakes, unless you’re on an incline. Surprisingly this will save gas because your car doesn’t have to put that extra oomph into holding the brakes for you, it will also give your brake discs a longer life.

When that light turns green, accelerate briskly and evenly. Taking off like there’s no tomorrow or crawling like a paralyzed dog will use a lot of fuel and **** off either a patrol car or the bloke behind you.

If you’re on a manual car, shift a bit earlier than usual, but not too early. Shifting late will be a bit like racing and that’s no good, shifting too early will cause your car to dump heaps of fuel into your engine to get that oversized gear moving. Just as a tip though, 4000/rpm seems to be the magical number for most cars, so try to stay below that.

While driving, imagine that the gas and brake pedals are the faces of babies- literally. You wouldn’t floor it, you’d simply touch it and apply pressure. This form of driving will make a huge difference because your car won’t need to add any extra effort to launch or keep at a crawl. Even if you intend to reach high speeds, you don’t have to bury your foot into the floor. You can get to any speed by simply pushing the pedal 40% down. Also while cruising, keep your speed and acceleration even. Hold the pedal down at it’s first inch of down-press instead of gassing on and off all the time.

If you have more than one possible path to take, take the one without the hill. Hills require an enormous amount of fuel to work up. If you must, however, then try not to accelerate as you go uphill. Instead, build up speed before the incline, and try to sail over the slope.

Also, when convenient and possible, try to take the freeway. Braking and accelerating from zero uses a lot of gas, much more than the steady pace of the freeway flow (if it is flowing). And for goodness sakes, whatever you do, do not be one of those drivers that puts their foot on the brake every 7 seconds. For most cases, taking your foot off the accelerator is enough to do any job that requires slowing down; most people underestimate the power of that. And if you want to play it safe then move your foot over to the brakes, but don’t push it unless you absolutely must.

Playing around with the gas pedal, brakes, and power steering wheel dumps chunks of fuel into the engine and melts your wallet which for some, is your heart. Even changing lanes will cost you, so watch the horseplay, and if you must, then do it slowly and in a civilized and responsible manner. Also be sure to avoid road puddles, potholes, uneven pavement, bumpy trails, young children, and elderly citizens, as they all lead to drag on your car and wear on your tires.

Red Light


For most people, the red light signifies as a halt, but as simple as it sounds, focus and deliberation is still vital.

The dumbest thing you can do is rush to a stop. If you think about it, then you will realize that all that built up speed must be suppressed quickly; you will use gas to go faster just so you can use more gas than usual to brake harder and stop. Not only that, you will wear down your brakes and go into bankruptcy with habits like these.

What you should do is coast into the stopping point. During my research, there has been much conflict regarding the advice to coast in neutral, or stay in gear. So out on our track, we were able to conduct the necessary testing. Our results were astonishing. For most newer cars, staying in gear actually turned out to be more fuel efficient than going into neutral. Because, while in neutral, the car burns a small amount of fuel to keep your car from ticking over and stalling, conversely, modern cars can use the momentum of the gears to keep your engine going, and use no gas at all! However, there are two things to consider on this note. First of all, you have to keep in mind that staying in gear will slow your car down much quicker than being in neutral. So if you surf up to 80 mph and then cruise in gear, you may only be able to cruise for 1000 ft before you have to put your foot down again, versus the 1700 ft you can cruise in neutral. So for long sails at high speeds, go into neutral, and for short cruises to the stoplight, stay in gear. Secondly, keep in mind this only applies to newer cars, and my best guess from the experiments would be 2004 and up. For all the rest of us, neutral is still your best friend.

Parking


The biggest question while waiting in the car is, “should I turn off my engine?” Starting up the car is equivalent to one minute of idling. So if you’re going to wait for more than a minute, then turn off the engine, and if you’re just grabbing something from the trunk, don’t shut off your car. Your name will suddenly change to Idiot.

Most Americans are so helplessly bound to their cars that they will drive to a McDonalds (obviously), and then drive 10 feet over to the bank which is in the same plaza, and then drive again to the Walmart which was right next to the McDonalds. Park in the center of your errands if they are within the same plaza and do a bit of walking for a change. Not only does it help your heart and give you that 2 minutes of exercise, but it also keeps your wallet filled, so you can buy more burgers and diet coke.

Also when you park, prepare for forward motion and slide when you can. What I mean by this is, the reverse gear is bigger and requires more fuel than your initial forward gear, so park planning to go forward if you can. And, for example, if you’re getting off your slanted driveway, slide off in neutral instead of using your reverse gear to launch you out so you can apply the brakes and deep-fry your cash.

Filling Up


There is a lot of commotion regarding what level you should fill your tank up to and how low you should get your tank down before you should fill up again.

One argument is that you should fill your tank up to the top and use it all the way down, because this is most efficient. Another is that you should fill your tank halfway up and use it all the way down because gas weighs 7 lbs per gallon and all that extra weight hurts your fuel economy. And another common perspective is that you shouldn’t let your tank get below ¼ full, because this requires the car to suck fuel out of the tank which uses electricity and thus, more fuel. All these points are true, yet when you finally consider each aspect, the best conclusion I can give you is to fill your car up to ¾ full, and not let it get below ¼ full. This way, your car isn’t loaded with weight, and does not require the electrical pump from your fuel tank. Also, better octane gas will give you slightly better mileage indirectly, because of the smoothness of the engine and simply the quality of the gas.

Two Notorious Myths


One myth refers to the time of day that is best to purchase gas. It is true that gas expands in heat, so filling up your car in the early morning will bring in more unexpanded gas than during a hot afternoon. However, the argument for that is that since gas is kept 10 feet underground in an isolated chamber, it wouldn’t matter what time of day you filled up, and the gas would come out the same temperature anyways, so it doesn’t matter.

Has anyone from the general public ever gone to the chambers below a gas station? I doubt it, not unless you eat manure. Is every gas station the same? Probably not. The problem with these arguments is that we don’t know, not only the validity of the arguments, but also the factors that can offset the arguments. So the best conclusion that can be made here, is that it is not a big deal to fret and rush to buy gas in the morning, but if you can, if it is convenient, if it is on the way, then do so, it just might help.

The second common myth is about the tailgate in pickup trucks. Pickup truck drivers have finally seemed to pick up on the idea of being aerodynamic and fuel efficient, but they only got so close. It seems pretty simple, a tailgate that is up blocks wind and works as an airbrake creating tremendous drag, so the most logical solution will be to put it down. Unless of course, you have cargo, then it would be the least logical solution. Yet, recently on an episode of Myth Busters, they tested a truck by driving it with the tailgate up and then down. The results surprised everyone. The truck actually has more drag when the tailgate is down, and you loose up to 4 miles per gallon!!

What happens is that, when the tailgate is open, the air travels over your truck and into the bed creating a whirlwind effect and thus causing down-force. This unusual stream of aerodynamics will hurt the air flow on your truck and create extra weight. Having the tailgate up is nearly equivalent to having a topper over your truck bed; no air gets trapped inside. Shocking, yet proven.

Maintenance


Taking care of your engine, using clean fuel injectors, quality synthetic oils, checking and replacing O2 sensors, ignition wires and other simple tune-ups are easy, cost effective, and bring the best performance to your car.

Even washing and waxing your car makes a difference. As bizarre as this sounds, having a smooth body of your car will help air glide over, thus improving aerodynamics. So get to it.

Bad mufflers and catalytic converters will seriously hurt your mileage as well because it prevents your system from having a proper airflow. So for all of you cheap eBay-exhaust hunting supercharged rev-freaks, buying quality products is the best way to go and it will prevent your wallet from stabbing you in the heart.

Smart Moves


Purchasing a car with manual transmission can gain you up to 3 mpg and cost nearly $900 less. However, this still depends on your driving style and all the tips mentioned above. Automatic transmission loads a bit of extra fuel between each gear change to ensure that all is going silky smooth.

While purchasing a car, note the EPA estimated mileage. However, don’t forget to subtract about 30% of that number, because of the silly methods that the EPA uses. You would have to drive naked in a giant room with no air at 6 mph if you wanted to match the EPA’s methods.

Buying items such as fuel line magnets and other gas saving party toys is equivalent to opening a bag of manure with your face. It’s not only completely useless, it’s also stupid and makes you look like a fool. They have been proven not to work, and beyond that, hurt your fuel economy. So don’t buy that heap of rubbish, and if you’ve already got one, then discard it for the sake of the additional weight.

Track your miles per gallon. When you fill up, note how many gallons you put in, then take that number and divide it by how many miles you’ve just traveled. That’s your MPG. Then reset your trip meter and try to beat your old MPG.

Conclusion


As you can imagine, this really changes the way you drive, you have to be so much more careful and focused on your every move, you have to endure all the hardships that the sun and rain may bring you, but think about it, you can’t possibly crash. I mean, you are concentrating so hard, that there is no way you can get into any stupid accident. If only everyone drove this way, there would be no more car collisions. So there you go, five pages of a comprehensive report on how to save gas, money, and your life. So share it with your friends and family and feel free to e-mail me with any comments, suggestions, ideas, anything.

Take care,
