Hi everyone,

What gain in gas mileage would I gain from driving on Eco vs. standard?

Thanks

For me, approximately zero.

Now, it helps one keep from accelerating too fast more than anything, I think. So if you are mostly city driving, it might help. I don't think it does anything much more than that. Even in eco, I get about 21 mpg, overall... Same as when I don't use it.

Agree with bsnguy, I only use Eco with cruise control. Smooths out accellerations.

I ran a few tests when I first got the vehicle. 2 weeks in Eco. Sport and standard. After six weeks of driving the same distance, all three modes produced the same MPG's.

I agree with Yeller. The only time I use it is in bumper to bumper traffic because it helps me hit the gas too hard. I'll have to try it with the cruise on to see the difference.

I find that driving with a hypermiling mindset helps, like trying to cruise slowly than constantly stopping and going.

I'm going to change the engine oil to 0W20 Amsoil synthetic, and CV trans fluid to Amsoil synthetic also and K&N air filter to see if my mileage improves. I used to own a Chevrolet Tahoe that I did that to and it did get better than avg. I'm just surprised that the Hybrid model doesn't get the avg.mpg that's advertised.

In flat as a pancake Louisiana we're averaging over 23 mpg using mostly the sport mode. Never will win a drag race but well satisfied with the mpg's! :D

You got it! But the difference from sticker is more like 5-6 mpg. I don't mind the actual performance for a vehicle this large, but the notion you can get 26 mpg is a bit ridiculous under typical circumstances.

EPA testing must've been done on a downhill slope. :-/

With only 1200 miles on the clock so far (car is about 4 weeks old) my 2016 QX60 AWD, is averaging about 20.5 to 21 MPG. I'm not Punching it either, 70% highway[NY traffic conditions] , 30% suburban driving. There are reviews from many sources - Edmunds, Car & Driver, etc., that say the same thing: They are NOT achieving the EPA rated mileage. You have to keep in mind, that all cars rarely achieve the ratings. From what I recall the testing is done in a interior environment (no wind or weather affects), steady 50-55 mph speeds on level platform. Not sure about Climate controls on or off. The only car that I had that actually Hit and bettered the EPA rating was the 2013 M37X that I just traded at end of lease. I was getting 23.5 to 24.5 on the highway, with no traffic conditions at 65 or better speeds. I was quite surprised. And only slight variance with Winter gas Blends.

It's my understanding manufacturers don't actually do any testing, it's a computer-generated figure that's supposed to mimic the actual tests. Only the EPA actually runs this test when validating vehicles.

Also, I think the test states no AC.
