As factory recommended 35/36 PSI

 

Cold or Hot?

 

I've seen 31 several times cruising at that speed. Any chance you had a bit of a headwind? That can make a big difference.

 

17.2 here lol. 80% city driving. I tend to hit the observed speed limit rather quickly though.

 

Good point. My tire pressure is set at 37psi.
When I first got my 15 GS, I was driving it like an old lady. There seemed to be dead spots while accelerating in normal mode when driving with a light foot. I would use the Eco mode a lot in rush hour traffic.
I was about to take my car in to find out why the hesitation in the Normal mode, but decided to switch gas brands first. Made a huge difference in the way the car drove. Now, I only buy gas from those on the top tier list (http://www.toptiergas.com/).
I have no problem on the highway getting rated (19 city/29 highway/23 combined) mpg, but city driving takes a lot of effort to get those results. Not worth the effort to me, so I switched my display so that I don't see the fuel economy anymore!

 

Cold....always set tire pressures with cold tires

 

I manage to get 389 miles out of my tank of gas. I dont recall what the car thought i was going to get. I never chevked that. I'll get pics for you next time I'm about to fill up. No BS here.

 

429 miles on my last tank, took 16.5 gallons to fill it (I top it off every time) = 26 mpg. 240 of those miles were hwy.

I pulled into the gas station with zero miles on the range screen once and put in 16.5 gallons (topped off). From that I guess you have a gallon reserve when the range goes to zero.

 

When I drive to NJ....300 mile straight shot, I get around 29-31MPG. Going to work I get 15-16 local, which is awesome cause my CLS55 was giving me 9MPG total lol

 

my last long trip about 135 miles each direction I averaged 28.5 mpg driving in ECO at a avg speed of 64mph

 

man yall do a lot of highway driving. I am doing city every day, maybe that is why I can barely break 17mpg. I want 300 miles damn it.

 

Akuma88, here's the picture I promised. Forgot to take it the last few times I filled up. Almost forgot to take it this time as well but quickly remembered after driving a bit. May want to get your car checked if your getting super low miles. I drive in normal mode btw.

 

Combination, city, country, hwy......I average 22 at about every fill-up....with Costco 93 premium grade.

 

My hybrid said I had 30 miles to empty (getting 30mpg) that should be one gallon left right? So I should have filled up with 16.2 gallons (for a 17.2 gallon tank). Nope, took 15.3 gallons to fill it. so I really had like 55 mile of range. This might be what your seeing.

Can anyone verify if in fact we have a 17.2 gallon tank?

The wife's 2011 V6 Durango gets 16 in the city and 22 on the highway (on a good day, bad day highway is 19). That highway # is 100% highway. That thing would never get 18.5 in the city (and it's slow as hell).

 

I do about 70% Hwy & 30% City and I usually average 20 to 21 mpg. I always drive in normal mode and haven't really messed around with the ECO Mode yet. Does the Eco mode really make a big difference?
