1600 mile road trip...

[elcameano]

Well I just got back from a 1600 mile road trip and all went well except not real impressed with mileage. Went through 5 tanks of gas and best was just over 17 mpg and worst being 14 mpg. Other then the 14 mpg tank it was all hwy driving most of the time cruise was set. It got 16 mpg one tank on a stretch that I was running 75-80 the whole tank cruise set. There was 4 ppl and 2 dogs in the car and luggage for 4 days so I wasn't pulling a big load. I was wondering what you guys thought about my mileage?

Oh and all were figured at the pump not going by the DIC

That is not bad mileage with that load.
4 people, 2 dogs and a luggage is at least 500 pounds. Meaning you will lose around 40-50% of your mileage. Factor in an intermittent full tank of gas and you actually did pretty good mileage wise.

Ok thanks for input! I was thinking of doing a blackbear tune, cai, and maybe a muffler. Anyone having any mpg increase doing these mods on nnbs Tahoe? I noticed some gains on my short bed after doing these things.

I have all those mods and you will gain 2-3 MPG if you can keep your foot light on the pedal!

You and me drive about the same I drive 73 miles one way to work. And I average 18 too that's with 95% highway.

I did all three of those on my 08 Tahoe and I had no mpg gains

My AEM CAI and BB Tune gave me a couple MPG highway for sure.

I've never had any luck getting any real MPG gains with a CAI.....

Mileage seems low to be honest. My Denali XL AWD got that mileage on our big trip back east last summer. Usually 17-19 mpg on the highway, cruising 5 over the speed limit (70-75). Worst was heading west across Wyoming at around 15.5 mpg. Big headwind that was enough to reduce the 18 wheeler's speed to around 65-70.

My load was 4 people (around 430lbs) and luggage for 2 weeks (probably another 300-400 lbs, plus gifts on the way there and souvenirs on the way back).

As far as CAI/tunes goes if your primary reason to get them is gas mileage then you'll never get your initial cost back (kind of like Hybrid vehicles).

Its a big SUV so I dont expect to get the best mpg. It does some kind of weak compared to my little truck, which the hoe weights lots more and is in stock state of tune. I would be nice to have more pep and if I get more MPG then thats a bonus.

I was kind of thinking that the 6.2 doesn't have to work as hard as my little 5.3 and with the 6 speed requires less throttle to get up to speed. May be wrong...

I headed south from southeast Ks to east Tx into a decent head wind and then headed east to New Orleans. I would say we had around 700 lbs in car with the 4 ppl, 2 dogs, luggage, and dog kennels.....
