How about some gas mileage reports?

[Quark]

36 psi in door panel. I always ran 2 psi higher. It’s not the 5k avg.
snapshot in time 50 mile average. All highway

Still is a nice average. Were the conditions neutral or advantageous?

What type of suspension do you have? Are you normally critical of ride?

Sorry for sounding like an inquisitor I'm just trying to get a baseline for expectations.

2006 Esky Base, 3.73 AWD

Road trip home after purchase of 526 miles averaged 18.2
Couple trips to my cabin and back, 16.6
Daily driver 50/50 city/hwy 14.7

Thats a bit bigger of a hit to the fuel mileage than I wanted. But it is 1000 lbs heavier, and no highway gears. So I am good with it.

5.3 here.
Haven't driven too much on the hwy but got about 15-16 on the hwy about a week ago. Currently, been doing only city driving and averaging about 14-14.5 mpg. Price round me for gas is 4.05 for mid. That's the lowest I've seen in the last few wks.

For no real reason, in the Midwest fuel jumped at least .25 $.30 a gallon in the last few days. RUL is now 3.15-3.20. PUL 3.95…
Thankfully, Diesel still 3.09…..

Nice. Yea I think I read somewhere prices have gone up here in SoCal approx 0.40+ cents within the last couple of months.

I’d be highly skeptical of any V8 owner saying they regularly got in the 20’s

totally spot on above
if you aren't hyper mile'ing (55mph or less, mileage tires, empty truck and a focus'd driver) you aren't getting 20's by the tank in a full sized v8 4x4 from GM

in the diesel; totally different animal

I often average over 22mpg highway at 65mph. A recent 170 mile round trip averaged 21mpg counting a city bypass route with umpteen traffic lights. Admittedly I have a light foot and coast into red lights.

21 Yukon XL 5.3 SLT. Most of the time I average 14-15 mpg around town. Much of my daily driving is short trips on heavily congested Northern Virginia.

On a recent trip from Virginia to Michigan I was very happy to exceed the epa rating. The average was 21.3 westbound and then 23.7 eastbound. Makes sense because wind is usually coming from the east. Cruise control at about 75 most of the way both directions

Denali 6.2L premium here, just did 1k mi round trip mostly highway, got 18.3. In town, around 14.

I know they say if you're buying a big SUV you shouldn't care about the gas mileage but I'm not one of those. I would be quite interested to know what our courageous buyers are seeing especially on the 5.3L. Trips, combined city highway, from the DIC or hand calculated all will be appreciated. How fast you drive, load of vehicle, etc. the more info the better.
