Drive Sensibly
Observe the Speed Limit
Remove Excess Weight
Avoid Excessive Idling
Use Cruise Control
Use Overdrive Gears
two things that really helped me was closing my windows and not using your AC cause the compressors are working when you use that and that makes your MPG BBBADDD

Air on or off doesn't seem to effect MPG on a 2011 CRV 4 cyl AWD.

By timing traffic lights to/from work - tryig to avoid a complete stop - I pick up a few tenths average MPG over a 5 day period.

I have found if I run my GMC 1500 under 2100 rpm and run 61-63 mph I actually get about 18.3 mpg rather than the 15.7 I get when running 70. Not bad for a full size half ton 4X4 with oversized tires.

Just keep noticing your speedometer,but start glancing more at your instant MPG indicator,learn what is the best/highest reading on the MPG, then adjust your driving habits to the best reading,compare that with the speedometer range ,then You Got It if action gets transfered to your right foot =(more often,repeat)this process for more fuel savings............

A one time practice or even several won't produce much results but over time,good decisions,when traffic doesn't have the greater handle on the driving event,that savings for me was a big difference,mainly at speeds over 45 mph. My results were with practice (cruise on and off/various speed ranges) G/Luck!...

For those waiting for intelligent cruise control, that will make you go at the speed of other traffic, have fun. Some how I figure out how to drive at the speed I decide with the cc working and get around slower traffic. I'm not looking for something that drives my car, that is what I enjoy doing in the most efficient manner available.
It's like the new lane departure systems, great idea and from someone who used to have real issues with dozing at the wheel, very helpful I'm sure. However, geometry hasn't changed much in the past 2k years, the shortest distance is still a straight line. Why should I follow the lane around a long curve in the hwy when if the lane to the inside is open and I can forego driving out that extra 15 feet and back across the same distance at the other end. On open roads with several lanes just time your changes so they don't get in the way of other drivers. Not that hard to do, savings, insignificant, but then again I enjoy driving.

save gas by shifting to neutral on a downhill, approaching/waiting for a red light/stop sign, and when waiting at the drive through. Also when you realize that you are speeding, shift into neutral and coast back to the posted speed limit.

There is a good series in Globe & Mail's "Globe Drive" section about Lorraine Sommerfeld's trip hypermiling across Canada this past 2012 June/July: http://www.theglobeandmail.com/globe-drive/car-life/across-canada-on-four-tanks-of-gas/article4386735/

Go to Globe Drive website and search "Hypermiling" to get all 6 articles covering the 6,300 km trip across Canada, east to west.

How’d we do? We covered those 6,340 kilometres of varied Canadian terrain with 4.69 tanks of fuel. We
averaged 1,352 kilometres per tank and 5.59 litres/100 km to establish a savings of nearly 32 per cent above
the manufacturer’s figures. Also telling, the diesel VW Touareg TDI that tailed the competition car saw an
improvement of nearly 23 per cent, using air conditioning and paying less attention to stops and starts.

The G&M also has a 2010 article by Roy McGregor on 20 ways to improve your fuel efficiency: http://www.theglobeandmail.com/globe-drive/car-tips/20-ways-to-improve-your-cars-fuel-efficiency/article1379796/
as well as a link to Helen & John Taylor's website about their world-record setting hypermiling exploits: http://www.fuelacademy.com

I agree with the cruise control statement. It's just not intelligent enough on most cars. I much prefer to drive the car. Now, when really intelligent cruise controls (adaptive) become available that maintain proper distances between cars and can analyze the road grade ahead, then I'll use cruise control more.

Also, very interesting stuff on A/C compressors. Now more and more cars will have electric A/C. That will help mileage a bit too.

Hotwire...., it's amazing how many folks can't figure out how simple cc is to work with. I use the same technique to slow for some traffic and the when it opens up I use the Accel button to get back to my cruising speed, hardly ever touch the brakes.

I take advantage of coasting as much as possible.
I like the way my cruise control works. Every time you back it off that equals one mile per hour. So whern I'm climbing a hill I start to back it off to avoid from shifting down. As long as I can keep it from shifting down I hardly ever notice a drop in gas milage. Depending on the length of the hill will decide how many MPH I need to drop. I hardly ever have to drop more then 3 or 4 MPH. As soon as I top the hill I start bumping the cruise back up to the speed I was traveling at. On my truck I will notice a drop in gas milage as soon as it starts shifting down.

Like most things, using cruise control when the road isn't flat depends on several factors. In my truck that is probably true since the way it engages and causes downshifts up grades is wasteful. On the other hand in my Corvette 6speed it hardly ever finds a hill that will bog down the engine and can maintain constant speed with very little effort. Going into the mountains is another issue but most of the time, flat or rolling hills the cc is very effective when you have lots of torque and low weight.

Anticipate traffic patterns ahead of you and react accordingly. If you see a red light ahead, immediately start coasting and brake if necessary, your goal is to maximize coasting time as that is when the fuel injectors in most modern cars shut down, in other words you burn no fuel. If you time everything properly with the coasting, you should not have to come to a complete stop at all as the light will have changed by the time you reached it and When you pull away, accelerate slowly and steadly.

reb4 - If the traffic flow is better in-town than on the highway I would go thru town as well. Ther are times when it's like that here as well like race weekends since the highway that I would use to leave work is the one one that is used to go to the race track for the nascar race. So the afternoons when those races are getting out I avoid that highway go thru town and pick up the other highway I get on to head toward home. Sunday afternoons are like that as well because people are heading home after being up in northern NH. My work place is right next to the highway so when I leave I see how traffic is moving before I get on that highway. If it's backed up I'll avoid it, cross town and get on the other highway to head home. But 90% of the time that isn't the case. It depends on the time of day I'm leaving work.

Wash your car. Air takes longer to move around dirt creating more resistance.

If you want to take the time and money, lower your car. You could also go to the extreme and put lighter wheels on it, short throw shifter, low resistance tires, new exhaust and so forth. You would have to drive forever in order to pay it back off :)

pinbuster2005, must be nice in New Hampshire, even on weekends there are inevitably a lot of traffic on our Highways in Chicago. I use some alternatives with better traffic blow and do just fine. I also have a hybrid that gets better gas mileage in City (only 3 on epa scale which I inevitably beat average... )

I can understand your logic since most cars get 10 mpg less in city driving over Highway, which is why Manufacturers always show the highway number...

Avoid in-town/city driving as much as possible. If you need to go someplace at the other end of town/city and there is a highway that can take you there use it. You'll be avoiding the stop and go traffic and the lights. Even if you have to double back a little bit it's worth it because of the more consistant speed you'll be driving.

Also do your regular routine maintainence on your automobile as often as your supposed to. By changing the oil/filter, belts, ect you'll keep your automobile at peak running condition and getting the best possible mileage out of it.

Another way to get more MPG is to reduce the friction as much as possible throughout the drive train. In 9/2011 I bought a 2003 VW Jetta TDI that got highway mileage of 45.3 MilesPerGallon on highway trips. After changing the engine oil & filter and the transmission oil, my highway mileage jumped to 50.5 MilesPerGallon. It's nice to be able to go more than 550 miles on one full tank of fuel.

"Remove Excess Weight"

Not really. I calculated for every 100 pounds of weight I add or remove it makes a difference of 0.2MPG on the highway at 65mph.
Slightly more in stop and go traffic and when going up hills.

How about the people who forget to take off the parking brake all the way.Do it once maybe warp the rotors or discs and you will have rubbing till their fixed. Friction = poor milage too!

Be mindful of upcoming stop signs, lights etc. slowing down and breaking less sharply & take off slowly being mindful again of avoiding quick starts ( that eat up gas & your mileage)

Let your engine pump better add some headers straight pipe exhaust and an open air filter. Get some synthetic oil and add an air dam. Why not take it to the extreme level. Switch to efans (if you don't have them) cover up your grill and route your heater core to blow out the side (and turn the heat way up) fold your side view mirrors add a carbon fiber hood and some fiber glass fenders and some lexon windows. Then remove rear seat (if you have one), remove the carpet, get some bucket seats, remove radio and dash, ditch spare, get rid of ac system, remove windshield cleaning equipment, get a lowering kit. At the moment thats all I can think of to REALLY boost mpg but most people won't do the extremes for obvious reasons.

60% of America is 30 lbs overweight or more and many of them are just plain outright obese so if you fall into that group go on a diet...better yet, get the whole family on a diet as more than likely they are too.

Avoid harsh acceleration and braking -- drive smoothly at a constant speed
Drive downhills all the time

Change your spark plugs, air filter and fuel filter every 2-4 years depending on your driving. If they are in poor condition, your engine will not burn gasoline efficiently.
Have your oxygen sensors tested every 2 years, replace them as necessary (their only job is to keep your car fuel efficient).
Keep your tires at their proper inflation (check them every 1 or 2 weeks, just before driving the car). Your tire inflation changes by a lot when the temperature suddenly rises or drops.
