What MPGs are you getting?

[MSBlackZ]

I'm riding stock right now and have thought about getting a leveling kit and some aggressive A/T tires. What kind of MPGs are you getting?

I'm currently averaging 15.5 on stock ride with Firestone destination LEs.

Just a bonus question. What leveling kit are you riding?

Thanks

Lots of factors here.

On 22s I also have a BB tune
easy on the gas and doing the speed limit. I got as high as 20mpg highway
Normal every day driving i get about 18mpg highway

on winter 17s all highway
i can get up 22mpg Granny driving
about 18 everyday driving.

roughly 16 around town, 22ish on a nice haul.

Best I've done of the highway is 16. That's with a leveling kit and 22s cruising at about 70-75. I have a really heavy foot and only average 12-14. lol

On my NNBS I get about 17mpg highway driving at about steady 85mph and combined with some city driving I get about 400 miles to the tank.

Do you credit the BB tune for the good numbers what other mods. I ask because i have a 44 muffler and K&N 63 series intake and seriously thinking about the auto cal tuning option from BB

I do think that the Tune helps. This is after filling up and hit the highway. It want as high as 23 avg mpg.

i'm getting like 13 in the city an 16 highway, but my angles have changed an my tires are about twice as heavy as stock

Around town, best to date and pulling a 7x14 dual axle enclosed race trailer.

BTW, the truck is an '11 Suburban Z71.

Well I get anywhere from 9-10.5 all city driving but I have a pretty heavy foot. That's with 34.5s though. Its depressing to fill up for $85 and have a 250 mile range.

Best I've ever done^
15-16 is average.

Are any of you guys manually calculating your numbers or are you just going off of the DIC readout? How accurate is it? I just got my tahoe so I've only gone through a half a tank, but I use an app called FuelTracker on my phone that goes off of mileage. I just reset the tripmeter each fill up, then enter the mileage traveled, gallons used and the gas price (why it requires the price I don't know...has no bearing on the number), and viola. It keeps a running log of your fillups so you can see at a glace if something's off with the numbers.

I was averaging 12.8 in my land cruiser...my Tahoe seems like a goddamn prius in comparison!

07 Z71 see sig for mods. Recently hand calculation indicates around 15 mpg city and 16 mpg highway @ 65 mph. Winter gas is ~14 mpg city and 15 mpg highway (sometimes less than that).

Just pulled a ~3,400 lb camping trailer and got ~12.5 mpg round trip combo highway and rural driving with some steep grades.

BB tune made a big difference to correct the speedo (after larger tires) and tune for 89 octane. Keep in mind that I have the 4l60e tranny and 4.10 gearing.

I'm lucky to get 13 city/ 14-15 hwy since I put on the 275s
