I may sound like a total idiot here...but what does it mean to hypermiling? I never heard such a phrase or word. Can anyone explain how i can do this? Is hypermiling good for your car?

I got pretty drunk last night and the wife was driving me home after the wedding. She was in fourth gear doing 35MPH revving at whatever it revs at (2000) or so ... I bit my tongue but I just wanted to scream "IT HAS TWO MORE GEARS YOU KNOW". She was doing it for like 5 minutes... !!! Oh well.. I'll never get 50MPG with that going on.

Hypermiling I think has no detrimental effect on the car. It just basically means driving with fuel economy as one of the top priorities (after safety, of course). Generally driving the speed limit and using everything else in your arsenal to save gas (check the forum, tons of hypermiling tip threads on here)

Hopefully she was sober. I'll take 10 MPG over dead any day.

Hyper miling, when done correctly, is both safe for your car and not dangerous to you or those around you. Basically it's learning to drive to improve your fuel economy. In fact, mild hypermiling techniques are taught in drivers' education courses. They call it defensive driving. Here's some links:

In addition to these, many hypermilers have scanguages to get a more accurate picture of what their car is doing. Personally I think anyone with an ECO (gas or diesel) can get the benefits of the instrumentation simply by learning to use the tools and displays the ECO ships with. The Cruze can be set to display in US, Metric, or Imperial. Ignore the Imperial option unless you're already comfortable with Imperial gallons and miles. The US display is best used for fuel economy values below 99 MPG. The metric displays are the only way to track numbers above 99 MPG. In order to see what your car is doing above 99 MPG, use metric and the following table:
| l/100km | mpg | Low | High |
| 0.1 | 2,352.1 | 1,578.6 | 4,704.3 |
| 0.2 | 1,176.1 | 944.6 | 1,568.1 |
| 0.3 | 784.0 | 674.0 | 940.9 |
| 0.4 | 588.0 | 523.9 | 672.0 |
| 0.5 | 470.4 | 428.4 | 522.7 |
| 0.6 | 392.0 | 362.4 | 427.7 |
| 0.7 | 336.0 | 314.0 | 361.9 |
| 0.8 | 294.0 | 277.0 | 313.6 |
| 0.9 | 261.3 | 247.9 | 276.7 |
| 1.0 | 235.2 | 224.2 | 247.6 |
| 1.1 | 213.8 | 204.7 | 224.0 |
| 1.2 | 196.0 | 188.3 | 204.5 |
| 1.3 | 180.9 | 174.4 | 188.2 |
| 1.4 | 168.0 | 162.3 | 174.2 |
| 1.5 | 156.8 | 151.8 | 162.2 |
| 1.6 | 147.0 | 142.6 | 151.8 |
| 1.7 | 138.4 | 134.5 | 142.6 |
| 1.8 | 130.7 | 127.2 | 134.4 |
| 1.9 | 123.8 | 120.7 | 127.1 |
| 2.0 | 117.6 | 114.8 | 120.6 |
| 2.1 | 112.0 | 109.5 | 114.7 |
| 2.2 | 106.9 | 104.6 | 109.4 |
| 2.3 | 102.3 | 100.1 | 104.5 |
| 2.4 | 98.0 | 96.0 | 100.1 |
The first column is the car's readout in L/100 KM. The second is the direct conversion to US MPG. The third and fourth columns are your "error bar limits" based on the fact that the first column is a rounded number.
The one number that isn't on this chart is 0 L/100KM. The Cruze will display this whenever the fuel injectors have been turned off and the car is using wheel spin to keep the engine turning. This mode is called Deceleration Fuel Cut Off (DFCO). In order to enter DFCO, the engine must remain turning at 1500 RPM or higher for at least two seconds (Manual Transmissions) or four seconds (Automatic Transmission) after you let off the throttle. When you are on Cruze control, DFCO will also be entered when ever possible. The Cruze will come out of DFCO when the engine speed hits 1200 RPM, the throttle is pressed, the ECU needs throttle for the Cruze control, or the driver puts the clutch in. The automatic transmission appears to remain in DFCO through downshifts. Some people have complained about the slight surge felt whenever the car enters and exits DFCO while descending a hill on Cruze control, but this is normal and isn't harmful to the car. In fact, if you're paying attention you can even feel the car entering DFCO as well.
I use three displays - Speed/Range/Instant MPG, Trip 1 or 2, and the ECO's game displays. The last is unfortunately not available on non-ECO trims. For those of us with 2011 and 2012 ECOs, 4.7 L/100KM = 50 MPG, so you can see how well the rolling averages are doing as well. The formulas for conversion are 235.2 / MPG = L/100KM and 235.2 /(L/100KM) = MPG.
If you want to see threads on individual efforts at hypermiling, they are in the Fuel Economy sub-forum.

^ Awesome stuff. I use the same displays but I use the game display the least. I try to stay on the instant MPG as much as possible because that' shwere you learn the most about how much the gas pedal affects MPG. Just staying on that screen I have gained 3-4 MPG in the city. I have my Scangauge that tells me my average anyway and I have my gauge tuned that it tells me what the DIC is doing, only its even more accurate (last fillup DIC was 1.5MPG off or so and Scangauge was right on.
If I use DFCO mode in the city properly I can easily hit 40 MPG unless I hit a storm of red lights.

Check this link to post #100:
Speed vs. MPG charts (post 'em if you got 'em) - Page 4 - Fuel Economy, Hypermiling, EcoModding News and Forum - EcoModder.com
I posted that somewhere on Cruzetalk also, but I can't find it right now.
If you go to a flat road and do two way averages resetting the DIC to get your mileage over the same stretch of road you'll be able to compare your numbers to what I got. Read this guide, it will tell you what you need to know to accurately (as possible) determine your consumption vs. speed:
How to properly test modifications (AKA: don't believe every MPG claim you read) - Fuel Economy, Hypermiling, EcoModding News and Forum - EcoModder.com
Pick one or two speeds to test at and compare to my results. Keep in mind my results are corrected at -7% from the DIC, actual DIC readings will be higher.

The ECO MT just begs to be hypermiled.

Just pumped my tires up again. Last time I did them I had driven the car a ways to the gas station. I inflated them to 47 PSI which cold was only 43. Today I took them up to 49 cold. Going to see what the drive is like and then maybe go up to 51. I saw a pretty good MPG gain from 35-43 hopefully this will be the same!

When I first overinflated my tires I hated the ride... then after a week or so I just got used to it.

My MPG is slowly climbing. Last fillup (third one that counts) was at 44.6 MPG. Car has 1800 miles on it. I really thought it would be doing a little bit better than this right now with the hypermiling I'm doing but the city driving is killing me... Gotta try to keep the curve going up!
I haven't reset my trip 1 computer since the 3rd day after I got her...Just to keep track of fuel mileage since new... Slowly going up .. Almost 5000 miles and at 48 mpg U.S. , I would like to get over 50 mpg for the first year but winter will no doubt mess that goal up
