Below are some hypermiling guides from around the net. Keep in mind that hypermiling techniques are debated by different hypermilers and that you should do some research before implementing any techniques. Be especially careful if a technique sounds unsafe. What's more important, gas mileage or your well being?

The Ultimate Guide to Hypermiling: 100 Driving and Car Tips and Resources

Hypermiling, or driving your car “in a manner that maximizes mileage,” has become more popular among drivers worldwide, as concerns over increasing gas prices and environmental issues heighten. Whether you’re trying to make a difference by helping the environment, or you’re just aiming to save a few more dollars at the pump each month, check out this ultimate guide to hypermiling, which provides tips and resources for smart driving.

Driving Tips

Below is a list of hypermiling tips that drivers can implement while behind the wheel. We recommend practicing one or two tips at a time and gradually working your way up to the whole list so that you aren’t overwhelmed.

1. Drive a stick shift: If you’re used to driving automatic, switching over to a stick shift might take a little practice, but it’s definitely worth it. Once you have more control over the vehicle, you’ll be able to master more hypermiling tricks.
2. Stop speeding: The harder you press the gas pedal, the more gas you’re using. If you’re driving over the speed limit, you might save time, but you’re definitely wasting gas and money. Slow down a little if you can so that you’re driving at or just below the actual speed limit.
3. Coast instead of braking: When you see a stop sign up ahead or a traffic light turning yellow, immediately take your foot off the gas and let your vehicle slow down by itself. If you wait until the last possible minute to brake, then you’re wasting all the gas you used when you could have been slowing down.
4. Cruise Control: One automatic setting that actually helps hypermiling is cruise control, which prevents “you from “creeping” up in speed without realizing it,” according to Epistolary.org.
5. Put your car in neutral: Coasting with your car in neutral takes the burden off your gas pedal preventing you from wasting fuel. If you’re not driving in heavy traffic, experiment with this effective money saver.
6. Lighten the load: The heavier your car is, the harder it has to work to propel itself forward. Empty out your trunk and backseat of ice chests, beach chairs, and other items that you’re not using to lighten the load.
7. “Shift slow and low”: The site Epistolary.org urges drivers to “shift slow and low,” whenever possible to give your vehicle more mileage.
8. Drafting: This technique comes with a warning sign: according to many hypermiling experts, it is incredibly dangerous. A “deliberate form of tailgating,” the forced auto stop involves turning off your car’s engine and then following closely behind the vehicle in front of you “in order to take advantage of the reduced wind resistance in [the other car’s] immediate wake.”
9. Find a route that’s easy on your vehicle: A story in the Washington Post discusses the benefits of “optimiz[ing] your route” when implementing hypermiling tricks. Instead of taking the scenic route to work, which could include more hills, twists, and dips, try finding a route that features level roads and less traffic lights or stop signs. Generally, “a longer route with better driving conditions” can use “less gas.”
10. Park in the sun: The blogger Joe Future believes that parking your vehicle in the sun is a hypermiling tip for two reasons: “On a cold day, parking in the sun keeps your car warmer.” Also, a warmer car “will get to “auto-stop” mode faster than a cold car, so you’ll sit idling at fewer red lights while you’re waiting for auto-stop to kick in.”
11. Roll down the windows if you’re not on the highway: After the scorching hot temperatures of the summer have retreated, stop blasting the air conditioner and roll down your windows. According to Drive.com.au, “It is generally accepted that air-conditioning increases fuel consumption by about 10 percent but winding down the windows increases drag, which is also an enemy of good fuel consumption.” If you’re going to be on the highway, keeping your A/C on low is still a good idea, but if you’re taking a joy ride, think about getting a little fresh air.
12. Turn off the car before putting it in park: Joe Future suggests turning off your vehicle before putting it in park to save gas. If you don’t, “the gas engine will come on before you shut off the car.”
13. Don’t leave the car running: It may seem like a good idea to let your car idle while you dash into the store to grab the milk or drop off a rented movie, but doing so wastes gas. Take the extra few seconds to pull into a real parking spot and turn the car off first.

Maintenance Tips

Taking your car for regular check ups is another easy way to maximize mileage. Check out these helpful maintenance hacks that will keep your car running smoothly and efficiently.

1. Get an oil change: Keeping up with scheduled oil changes will help your engine run more easily. Adequate oil levels and lower-weight oil can also make a difference in how quickly your vehicle burns fuel
2. Check your tire pressure: Tires that are beginning to lose air and go flat put more stress on your engine, making it work harder and burn more fuel. Keep a tire gauge in your car and frequently check the tire pressure.
3. Engine Control Module: Your vehicle’s engine control module “controls various aspects of an internal combustion engine’s operation,” including the amount of fuel being used by the engine, the ignition timing, and the variable valve timing. Making sure your engine control module is working properly will help you gauge how much fuel your car is using on a regular basis.
4. Tire Balance: If your tires aren’t balanced correctly, you could end up wearing out certain tires faster than others, causing them to lose air and forcing your engine to work harder. Get a check-up for your tires if you think yours are out of whack.
5. Conduct a seasonal check up: During the winter, your car could become bogged down with extra weight from snow chains, heavier tires, or other items. During the summer, you’ll probably be using your air conditioner nearly every day. Before each season, give your car a check up to unburden it of needless weight and to make sure the engine, A/C and other systems are in proper order.

Tips for Serious Hypermilers

These tips are for the truly dedicated. Hypermilers should consider themselves warned, however. Some of these techniques are very dangerous.

1. Pulse and Glide: This guide provides detailed directions for the pulse and glide hypermiling technique. Accelerate quickly to a few miles above the speed limit, and then coast down to a few miles below the speed limit.
2. Warp Stealth: Click here for a detailed guide for implementing Warp Stealth on a Toyota Prius. This technique is achieved when “the car moves solely under electric power without the engine running.”
3. Ridge Riding: If you want to save gas during or after a hard rain, hug the right side of your lane, or the shoulder if you’re already driving in the far right lane, to avoid driving in the puddles created by other drivers. A more detailed explanation can be found here
4. Drive in electric mode: Toyota Prius drivers know that driving in the all-electric mode is “advisable” at the very end of a trip because “the batteries will recharge [more] quickly on your next start-up.”
5. Downhill run: If you’re driving downhill, take your foot off the gas pedal and coast all the way down until you absolutely must brake or give your car a little more gas.
6. Gentle rise and descent: The gentle rise and descent technique is based on the concept that only a “small amount of additional throttle will accelerate the vehicle before the rise is reached,” so that “additional power may be maintained on most of the upgrade.”
7. Accelerate moderately: Unless you’re trying to merge onto a busy highway, accelerating slowly preserves gas.
8. Run all your errands during one trip: Instead of running your errands several different times a day or spread out during the week, try stopping at the grocery store, video store, dry cleaning and (heaven forbid) gas station during one single trip. If you’re driving an electric car, this cuts back on its start-up time.
9. Park at the highest point in a parking lot: This tip from MSNBC suggests parking at the highest point in a parking lot so that gravity will “get your car moving” when you turn it on again.
10. Cool yourself down with an ice vest: Hypermiler Wayne Gerdes refuses to turn on his car’s air conditioner even in the summer. Instead, he wears an ice vest to cool himself down inside his stuffy vehicle.

Hypermiling (Saving Lots of Fuel) in a Hybrid

How to Get Maximum Fuel Mileage From Your Hybrid

Pulse and Glide (P&G)

This is the heart of effective hypermiling for full hybrid vehicles.Though it takes some getting used to, and it's really only appropriate for light suburban and town traffic, large FE gains can be had using it. Our first successful P&G was in a Nissan Altima Hybrid. This car is equipped with Toyota's Hybrid Synergy Drive (Nissan licensed it from Toyota), but our car was lacking an energy flow monitor, so we had to rely on the EV mode display and the Kilowatt (kW) meter to execute the task properly.

To initiate a P&G, accelerate to about 40 MPH with the engine running (the pulse part), then ease off the pedal until the hybrid system goes into EV (electric vehicle) mode and the kW meter shows zero (or if equipped with the energy flow monitor, no arrows are showing energy flow). This is the glide part. The engine is off, the electric motor is disengaged and the vehicle is literally coasting for free. When the car slows to about twenty five or thirty MPH (depending on traffic conditions, of course) repeat the pulse part, then the glide and so on. If properly applied, this trick uses the engine only to accelerate, and it never has the chance to idle along, wasting fuel while providing no return.

Forced Auto Stop (FAS)

Forced Auto Stop is similar to P&G without the objective of re-accelerating. In a hybrid, it is usually a matter of lifting the accelerator below a speed of approximately 40 MPH and letting the engine shut-off. This allows the car to coast to a slower speed, or come to a complete stop without the engine running. However, many conditions can affect FAS (adequate battery state of charge, hybrid system temperature, engagement of AC compressor, cabin heat, etc.) and is not always so simple. Depending upon the hardware and software controls of the hybrid system, there are ways to "fool" the system into FAS. Unfortunately, they are many and varied, and beyond the scope if this article.

Draft Assisted Forced Auto Stop (D-FAS)

This technique involves riding in the wake of a large trailer truck at highway speeds (in FAS). It's not safe, DON'T DO IT. We only mention it here because it is part of some hypermilers' arsenal of tricks.

Driving without Brakes (DWB)

More hypermilers' tongue-in-cheek terminology. We like to think of this as driving with minimal brakes, but it must be done with a good dose of common sense--it's really not a good idea to take a 25 MPH curve at 50 trying to save gas. The main idea here is to not use the brakes to scrub off speed that has been achieved with energy (gasoline) spent. Anticipation is the keyword. Look far down the road to anticipate traffic stoppages, sharp curves and signal changes and begin to decelerate or coast beforehand. The benefit is three-fold: Not only does DWB increase brake life, it reduces the number of times the vehicle must be started from a dead-stop (overcoming the inertia of a stationary vehicle consumes an enormous amount of energy), and, with a hybrid, the coasting action (regenerative braking) helps charge the battery.

Ridge Riding

This is the practice of driving very close to the outside edge of the road in order to keep the the vehicle's tires out of the slight depressions (ruts) worn into the road surface by the constant pounding of daily traffic. For most purposes, this technique is really only effective on wet roadways. Staying out of the ruts, which are filled with a thin layer of water, reduces drag on the tires and increases efficiency. An additional benefit is improved safety by preventing the tires from hydroplaning (riding on top of the water) and loss of vehicle control.

Face Out Potential Parking

This is just plain common sense with a little bit of exercise, to boot. Search out open spaces in parking lots to eliminate the wasteful movement of backing out of a slot. Go one better by locating a spot that is on a bit of a slope, and then use gravity to help get the vehicle moving from standstill. Sound silly? Multiply those effects over hundreds of park jobs in a year; it really does add up.

Fuel Consumption Display (FCD)

This is the gauge on the instrument panel of hybrids and many non-hybrids as well. Dedicated hypermilers call this the "game gauge," and in many ways, that's just what it is. This device continuously calculates a vehicle's average fuel consumption expressed in MPG (or, in metric mode, kilometers/liter) and displays it to the driver who can then make a fantastic game of making the average FE go ever upwards.

Instant Fuel Consumption Display (IFCD)

This instrument is very similar to the FCD, except that it displays fuel usage, just as the name implies--instantly--as it is used. The display changes moment by moment in response to sundry dynamic physical conditions: throttle off, light acceleration, heavy load, hard acceleration, coasting and cruising. This gauge, more than any other on a vehicle, hammers home the relationship between fuel economy and driving habits. Keeping the instant fuel consumption display relatively constant and even, with a high reading, will probably net more consistent (and easily attainable) FE than any trick or gadget outlined in this entire article.

And from a blog scraper website called Auto Motto,

DRIVE THE SPEED LIMIT
Goss says: Going slow can save gas. Goss says that once you go above 38 mph, you lose mileage. For every 5 mph above 55, you tend to lose 10 percent of your fuel economy.

DRIVING WITHOUT BRAKES: Maintain a steady speed if traffic is heavy.

Goss says: Do it when possible — but be careful especially in the Beltway.

TURN OFF YOUR CAR AND COAST: To save even more fuel when decelerating, shift to neutral and turn off the engine while coasting to a stop.

Goss says: Highly dangerous. You don’t have your car under control, says Goss.

OPTIMIZE YOUR ROUTE : To avoid traffic, try different routes. It so happens that a longer but smoother route saves a whole lot more gas.

Goss says: “Basic driving techniques. I teach this the first day,” Goss says.

WATCH YOUR TIRE PRESSURE: Some hypermilers recommend over-inflating tires as flat ones require more energy.

Goss says: It works but is very risky. “When you over-inflate a tire, you can compromise its traction and . . . make the tire wear out more rapidly. He adds that it is “very negligent to recommend that someone do that.”

STAY ON TOP OF OIL CHANGES: Use thinner oil.
Goss says: Goss reasons: It can have a significant effect on fuel economy, especially as the oil ages.The viscosity of engine oil is always increasing. . . . The thicker the oil is the harder it is to push through the engine.

From HypermilingForum.com,

1. Less Friction: It's simple, maintain proper air pressure and inflate to the maximum allowed by the specific model of tire you own. This will decrease friction and help your car get up to speed faster than tires that are at an improper pressure. In my experience, this is one of the most overlooked maintanence issues for car owners. Over the course of the next year, I will be doing experiments with tire pressure to show how much MPG's can be saved with properly inflated tires.

2. Remove the Junk in your Trunk: OK, it's not what you think. I'm not talking about getting rid of excess pounds off your rear end. I'm talking about removing items from your car that are not needed. These can range from books to trash to clothing to shoes, etc. I've personally dealt with this issue with my wife. She got into a wreck in my truck, so I bought her a newer car, and then I took her old car (Lincoln Mark VIII). Well, she didn't take good care of the car as far as the cosmetics go and the cleanliness. I found 70 pounds of books in the trunk that were supposed to be donated 6 months earlier and I found 60 pounds worth of dog food in the trunk that had been sitting in there for over a month. I also found some other odds and ends in the trunk and passenger area (blankets, cloths, probably 3 purses, trash, and more). The total weight loss after just cleaning up excess stuff out of the car was close to 200 pounds! I'm sure that didn't help gas mileage. Not everyone has a mess like this, but I'm sure everyone can take some items out of the car that will lighten it some. I will be experimenting with adding and subtracting weight in the car over the course of the next year and compare gas mileage.

3. Lighten the Load: This is similar as above. However, we're talking about lightening the car from it's original weight. Some things that could be removed and might not be necessary are trunk carpet, floor mats, rear seats (if you don't ever use them), etc. This varies based on car and use. You can also replace items with lighter models. In my case, I have two luxury front seats with power everything (they are pretty heavy). Since the seats are old, cracking, and the motors aren't working in them, I plan on removing bot of them and replacing them with lighter (but comfortable) racing seats for around 150 dollars. I will post how much weight this reduces in the forum when I'm done replacing them. Also, if you have a full size spare, you might want to consider downgrading to a smaller spare (these are pretty cheap at junkyards). There are many different ways of reducing a cars weight and I will go over my findings throughout the year.

4. Maintain your Car: As mentions in the Less Friction section, keeping your car properly maintained is extremely important to fuel economy. Change your spark plugs, oil, spark plug wires, coils, O2 sensors, tires, shocks, trans fluid, etc. at there appointed intervals. Sludgy oil, misfiring cylinders due to faulting spark plugs or wires, and badO2 sensors cause your car to run inefficiently and can lower your gas mileage.

5. Breathing is Good: Breath in, Breath out, Breath in.....Now imaging breathing through a stopped up nose. Not easy huh. It's the same with your air filter. Over time dust particles and such can block or slow down airflow to your engine. This causes your engine to work harder to produce combustion. Changing your air filter on a regular basis will help insure that your car is breathing right.

6. Brakes are not our Friend: Yea, I know. Everyone has to brake. But anticipating when you have to brake and braking at a slower rate can drastically increase your gas mileage. It's crazy sometimes, I've actually seen people speed up to stop at a stop light. They sit at the stop light getting 0MPH while you are coasting to the stop light still getting good gas mileage. Yes, you ultimately have to stop, but they sit at the light for 4 to 6 seconds longer than you, getting 0 MPG. Over the course of a year, that's a big savings. Video to come soon.

7. Aggressiveness: Do you use your accelerator like a crazed maniac, flooring it, then slamming on your brakes just to get in front of one car. If so, this is for you. I watch it all the time. I've seen cars weaving and out of traffic, slamming on the accelerator, then slamming on the brakes just to get around one or two cars, and then that same car takes a right turn just after making the pass. Not only did they affect their own gas mileage, they affected the car that they passed, because now that car must slam on it's brakes since the car that passed now is taking a right turn. Key here is to just be patient. Usually using this aggressive driving only gets people to where they want to go a few seconds or maybe a few minutes earlier than if they would have driven calmly. It could even be argued that you are wasting time by driving aggressively since you get worse gas mileage which means you probably have to the gas station more often.

8. Neutral: Use Neutral going down hills or when anticipating a red light. I've tried this a few times and my trip computer said I was getting 100 MPG at the time, and that's with a big V8 Mark VIII (granted, that is just the instant gas mileage gauge, not the full trip). This is much easier in a manual transmission as you can just push the clutch in and immediately go to neutral.

9. Rubbing is Racing (to quote Days of Thunder): This is somewhat a reference to drafting. Drafting is a technique used to lower wind resistance to your car by following closely behind a larger vehicle. Although, this can be dangerous if traveling too close and is illegal in some areas and states. This technique is used most often on long trips at higher speeds and doesn't help as much at lower speeds. 18 wheeler truck drivers have been using this technique for years.

10. Idle Time: If at all possible don't leave your car in idle longer than 10 seconds. This is probably the most inefficient part of driving since you are getting a constant 0 MPG the entire time the car is idling. Of course in some conditions and temperatures it might not be possible to turn off your car when idling, but whenever possible, turning off your engine while sitting in your car can save a lot of Miles Per Gallon.
