How many are using the ECO button, and when do you excatly use it. I have been doing a lot of local driving, never over 45 mph, Should I have it turned on?

CHECK YOUR RPMS AT IDLE with it on and with it off youll notice lower rpms with it on lower rpms less gas

Leave mine on all the time too. Like said previously, idle RPM's are lower. Also throttle response is somewhat slower. Not dangerous slow, just slower on the get-up-and-go. I'm mostly driving in the city with California's untimed traffic lights. So it's go from one red light to the next for me.

I now use it all the time. For the first 6 months of having the car I did not engage it - wasn't sure what it was. Then started using it. My MPG has risen by 2 + since using it.

Never use it in town. Only when going down the highway on a trip. It's really the only place it makes a noticeable difference in mpg anyway.

The salesman said use around town. I just leave it in Eco mode. No problems with gas mileage but best mostly highway has been 29.5 with 4 people in the vehicle, luggage and cold temps. When I see gas mileage and at fill ups I reset the average speed. I never realized who low my average speeds were.

You idle a lot in city driving (think stop lights) and ECO mode keeps your idle RPM's lower than without it so it is effective in city driving as well.

I disagree. Especially with the idle part. It's a negligible difference in idle rpm.

From an article:


http://blogs.cars.com/kickingtires/2009/06/chevrolet-equinox.html

Eco mode locks up the Equinox’s torque converter at lower speeds — most automatics do this at highway speeds — and changes shift patterns in the four-cylinder’s six-speed auto. It cuts the engine’s speed at idle, too, but it doesn’t affect the accelerator pedal. The net effect? About 1 mpg more with it on, Smith said.

“It could have a broader range,” he said. “We could get a lot more out of it than we did … but drivability has to be within certain acceptable limits.”

What are the compromises? For starters, in Eco mode the engine may start lugging at 40 or 50 mph, Smith said, like a manual transmission that’s shifted too early into its topmost gear. At idle speed, the engine can come off a bit coarse-sounding.

At what expense if it's lugging?

worried about lugging?? reach down and turn it off

My experience is just the opposite. With it off around town you can feel and hear the engine reving higher RPM and not uspshifting to a highe gear. Turn on ECO and it shifts sooner and the RPM drop significantly at say 35 mph.

This has also been my experience

I'll agree it might shift up in some case, but turn off you radio and listen and feel how the engine is performing in that higher gear. The engine is lugging and no mpg improvement is going to make that worth it to me. Just google effects of lugging on an engine. These DI engines are already showing to be prone to carbon build up this will only accelerate it.

I've had 2 Equinox's and the first I drove with ECO almost all the time. The second almost never. I'm actually averaging better mpg with our current Nox.

Yes I usually do not use ECO in and around town-driving. It may be slightly less MPG -- but drives nicer. On highway -- definitely better mpg. Also -- I drive with CC whenever I can. The mileage jumps dramatically. With ECO on -- on inclines and suburban highways - I can not duplicate the mileage I get with ECO using my foot. I do click off approaching a light -- but I can not get over a hill using less gas than my car in Cruise and ECO.

Radio is usually off, as I like to be aware of my surroundings, and no lugging, just lower RPM. Lugging usually happens around 45 mph, which I just give it some more throttle.

I used the ECO for the first 7k then turned it off until 11k. I went from averaging 22mpg mixed to 24mpg with ECO off. All in all it's just a gimmick.

Or, you're driving habits changed, or it was different weather outside, or you went from Winter gas to Summer-blend gas, or the engine is now broken in.

Many variables involved besides just the Eco button !

GM has done the analysis and says that the Eco button is worth 1 MPG. I am assuming that they have done it as a controlled experiment.
