Do most people here with a 2.4L use the ECO feature often or always?

The reason I ask is to me the shift point changes with the ECO on really don't affect my driving style, but the decreased idle speed is right at the point that it becomes noticeably just slightly rougher.

For that reason I have started keeping it off. I would rather have a smooth idle at the expense of 1 MPG.

Pretty strange, i tried 1 full tank without eco and 1 with. Im getting an average of 3.5, 4 liter/100 km. Probably the diffrence between our driving style. Since my dealer changed my oil for a synthetic one (5000 KM), i noticed a much stable, smoother idle and less valves ''tickling'' coming from the engine.

truthfully i hardly even use it. Maybe if i'm downtown in the city, but that is rare. It's only useful for what, under 45 mph anyway right? I also switched to full synthetic oil and as 2010nox stated things seem much "smoother" and i can already notice a light improvement in gas mileage.

Personally, I drive with it on all the time. I've quickly gotten used to how it changes the engine's and tranny's characteristics. So far i've only been averaging about 8.5-9.5L/100km - 50% mixed city/highway.

I have all intentions of going synthetic at the first oil change since I use synthetic in all of our vehicles.

It's just that I noticed the idle is just perceptibly rougher with the ECO on. I can sit at a light and turn it on and watch the RPM's drop a couple of hundred and then back up when it's turned off.

Oddly enough, I don't see the RPM drop hardly at all when I put on ECO on our 'Nox. I actually like the shift points a little better in ECO mode. Seems smoother.

I've noticed with the air on and ECO on it keeps the idle up at stops.

Most underpowered vehicles will bump up the idle when the A/C is on.

ECO on rough idle. AC on rough idle. Both on rough idle. I have noticed that if you slip the gearshift into neutral when waiting at a trafic signal the idle smooths out. Idle does not go up. Stays at approx 750 rpm. Hard to really tell because of inaccurate gauges.

The main thing the ECO does is lock the torque converter up sooner.
