Newby with ECO concerns

New to the Jeep World. Help with the ECO Button. I just purchased a 2015 Jeep GC and see little to no difference whether the ECO button is on or off. Is this normal? Thanks Jeffg

under normal acceleration, you should notice the trans shifts at lower RPMs with the eco button on.

Agreed. I use sport around town, normal on county roads, and eco on the freeway.

Re: Newby with ECO concerns

I noticed a difference in performance, did not keep it on long enough to see if it actually affected mileage. With ECO on, I noticed a hesitation when needing to accelerate that disappears in normal and sport modes. The ECO mode just makes the transmission upshift sooner and slower to downshift relative to the other two modes. Probably fine for highway cruising but definitely not for my driving style around town.

It's normal. Very little difference.

Re: Newby with ECO concerns

ECO off isn't as drastic as sport mode, but ECO off is noticeable to me. Atleast with my 2014 V8. The shift points go up noticeably. Then sport mode just changes everything and is a blast!

Re: Newby with ECO concerns

I have the 2015 v8. I don't care for ECO around town in the stop N go traffic. I found it shifted up to quick and then the transmission would be in the wrong gear when I needed to accelerate and it would cause the transmission to shutter ever so lightly. I use ECO when I get on extended highway jaunts.

For giggles, I throw it in sport occasionally.

Gas mileage blows in all three, so no real point for it imho.

My Touareg v8 had an ECO setting that basically would reduce the power of the air conditioning which I guess was supposed to help gas mileage. Never used it either.

Re: Newby with ECO concerns

I drive around in Sports mode most of the time. Definitely fun with the HEMI and despite it constantly holding 1-2 gears lower than normal mode, I do not feel like the gas mileage is all that different..

Was just curious why you use eco on freeway? From what I've noticed on the freeway it doesn't change anything. You're already in 8th gear and the rpms don't change between normal or eco mode once you're at highway speeds. I thought the only benefit using eco was city driving because it shifts sooner to save fuel.

You would get a slight benefit by up shifting into 8th sooner and maintaining 8th gear on mild upgrades rather than downshifting into a lower gear.

Ya, that hesitation, it'll make ya squeeze your cheeks tight in situations where u need, are r expecting, to go NOW. ECO mode on with that dam* electronic throttle hesitation can b a scary combo at times.
