Tires recommended pressure on my car is 33psi on all four tires. Tires on sidewall max pressure is 44psi. I maintain 40 psi as any more and the ride is to harsh and traction is lost around turns. Coast to red light. Drive 55. No jackrabbit starts. I have a cvt transmission and accelerate hold 2000rpm. Takes about 15 seconds to 60mph. With these steps I have seen a 20% gain in fuel economy.

You mean hypermiling? Higher tire pressure, coast more especially in anticipation of traffic and lights. Park and walk into the store instead of drive thru.

anticipate the road/traffic well ahead and adjust speed as necessary as to not waste fuel when its not needed it and achieve better mpg.

If you drive between 11pm to 5am, then most of the traffic lights are blinking yellow and you can just drive through them without stopping.
Its good for about a 10% improvement in MPG if you work it.

Yes, an amazing amount of fuel efficiency can come from simply not turning momentum into heat by using the brakes.

"hypermile"

The most important thing is "Don't be an a-hole."

Once you have mastered that, learn to anticipate and coast up to traffic lights. No hurry to wait in line.

Houckster, I get a kick out of driving in the city and seeing people race around me (i'm going 20 in 30 because light turned red) and they hit the brakes as I'm just pulling up... I did this with one driver for about 3 miles every time passing them up and they pass me racing to the red light...

I like to employ hypermiling techniques in my driving but with people having so many things to divert their attention, it's sometime uncomfortable coasting up to a light as people need those brake lights to realize that I'm slowing down. I haven't had any accidents yet but if we had more effective taillights we'd be better off. That's to say red for stopping, amber (or blue) for coasting and green for when you're on the gas.

When someone's on my bumper, I'll tap the brake pedal just enough to get the brake lights to come on so they know I'm coming to a stop. It's in these conditions that an amber light would be very useful.

As for speed, I'll stay with the traffic flow because there are some people who will do some very dangerous things to get around you.

Don't try to tailgate an 18 wheel trailer truck. It saves a lot of gas but it's so dangerous.

the most "bang for the buck" of hypermiling is to use as little brake as possible. brake = waste all the gas you just spent to build up your kinetic energy.

for local driving - look ahead at the light - no need to go as fast as possible to stop at the next light, when you can coast to a light that just turn green.

for freeway driving (in traffic) - build distance between car in front of you when the traffic picks up, then (this is the key) use at distant when the traffic slow down (close the gap!). I hate it when ppl dont close that gap when the traffic is slowing down.

I have not gone to any extremes, but I have full synthetic oil in my truck and the wife's car. Yes, switching to a full synthetic if you do not have it in already will give an increase in mileage. I also take it easy pulling out and try to coast without having to stop for red lights. I use 93 octane non-ethanol premium gas for both vehicles. At 55 mph on the highway my 2010 F150 FX4 with the 5.4 Triton V-8 gets right at 25 mpg. At 55 mph on the highway the wife's 2007 Chevy Cobalt with the ecotech 4 and auto trans gets around 40 mpg. Neither of us keep junk or extra weight in the vehicles. Air in tires is checked regularly.

I use a fuel economy meter to try to maximize fuel economy but I don't do any of the stupid practices of hypermiling like rolling through stop signs or otherwise driving like a Florida 80 year old.

I do hypermile but not all the time. wrt to tips...

You must go to the Source
=========================
goto the cleanmpg website and read the FAQs on hypermiling..

Time vs MPG
==========
hypermiling trades time for efficiency so you'll need atleast 25% more travel time to get where you are going.

Where and when you travel matters
============================
most hypermiling techniques work best when there is no or very little traffic on the road, when the speed limit is under 40 mph, when the road is dry and smooth, the weather is warm but not too cold or too hot, and when there are no stop signs or speed bumps or rumble strips.

YMMV depending on the vehicle.
===================================
A hypermiling technique called NICE gets its best results when using manual transmission - however, NICE is illegal in about half of the USA. hypermiling is easier with the stop-start/idle-stop technology which comes standard with most hybrids. The smaller the frontal surface of a vehicle, the lighter the curb/gross weight of the vehicle, and the more aerodynamic the outside of the vehicle-- the more significant fuel efficiency improvement potential a vehicle has when it is hypermiled. Low rolling resistant (LLR) tires can help increase hypermiling fuel efficiency. The best website on how to modify a vehicle to get the best fuel efficiency is ecomodder

eccerr0r brings up a very good point - don't impede traffic flow, and don't vary speed too much on a hill if you have followers, this tends to tick people off myself included. Generally when I do this I have the road to myself. Stick with the speed limit and set cruise at that when traveling long distances, if someone wants to pass you they can - this is the exact reason we have passing lanes. If you are on a multi-lane road way and you are driving slower than everyone else, stick to the right lane (although this is just common sense).

As mentioned by Seamus4513, paying attention to what is going on ahead of you is really the biggest thing to consider.

Thanks everyone for the comments. I do want to save gas and also be considerate to other drivers. Also I was corrected by another member, the right word is Hypermile not Hyghpermile.

Thanks

If you are hypermiling, please don't impede traffic flow...

If you are, likely you'll be wasting gas for people behind you (because they will have to brake to make sure they won't rear end you, and not all cars go the same speed) and irritating their tempers... plus you can get ticketed for it for not going with the flow.

I think having cars with regenerative braking really would save a lot of energy/gasoline, though there's not really a way to do this on gasoline cars... yet at least...

Use cruise control in areas where it normally might not be used (local 'superstreets' designed to keep traffic moving), maintaining a safe distance and keeping an eye out for coming traffic flow is probably #1, although many SoCal freeway drivers are very intolerant of this - keeping speed as consistent as possible. Buy a hybrid or other fuel efficient car.....

Here is the classic one - pertend that the brakes in your car don't exist (that doesn't mean don't use them if you really have too). Every time you use your brakes, you convert the kenetic energy of your vehicle moving down the road into heat in the brake rotors - not exactly a useful source of energy.

If you have a manual or a semi-automatic transmission, downshift to slow down instead of braking or coast as much as possible - modern vehicles often cut fuel flow to the engine when coasting in gear so everything is powered simply by the movement of the vehicle. This way you slow down, and use no fuel. Inversely, shift up at a lower engine speed and accelerate slower. When traveling on flat ground at 30~35 mph, your engine only needs to be turning at 1000 RPM. I generally shift into 5th at 30mph (although the gears in my car are close ratio).

When going up a hill it is alright to slow down a bit, likewise it is okay to speed up when going downhill - don't brake, use the turrain to your advantage. I ride hills like a roller coaster, slowing on the accents and accelerating on the decents - you can use the gained speed from going down to get back up the next hill if they are rolling hills.

Finally, stick with the speedlimits - it requiers significantly more power from the engine to travel at higher speeds and as such the engine requiers more fuel.

Drive like an old person - I'm a 19 year old guy and I do it because I get significantly better fuel economy. I generally average 35~37mpg around town with around 30% highway driving by doing this. I averaged 43mpg coming back from Columbus OH on the throughway doing 70 by riding the draft of other vehicles - but do this safely, keep your distance.

Sorry for the really long responce, hope this helps.
