2010 Denali/Mileage Question

[petethepug]

Yup, drive those 6.2L like you stole em and it’s your birthday …


Unless …

.. and 18 mpg on the highway with my wife sitting next to me.

My wife commutes 50 miles a day in our 2014 Escalade. 35 miles is a state highway at 60 MPH. The rest is in town will stop lights. While the Escalade is averaging 18 to 20 miles per gallon with the AFM deleted.... LOL, I must mention that she gets scared if she gets it over 2,000 RPM. I got her a set of pirelli scorpions, she has about 30,000 miles on them.... Not even 25% worn. Yep, her 6.2 should go at least 400,000 miles. She used to drive a Ford excursion with the 6.0 powerstroke.... But I got tired of having to blow out the carbon on the weekends ;-)

... I must mention that she gets scared if she gets it over 2000 RpM.

She gets scared of nothing? I feel your pain. She needs a larger engine, for more low RpM torque.
Maybe a 6.6L DuraMax?

Man, the first time I got behind the wheel of my buddies 1T quad cab long bed lifted 6.6L Duramax, intoxicating!

Absent after starting the thread. No gold star for good attendance!

He probably just waking up after New Year’s binge. Hopefully not pranked by being passed out on a couch left in the front yard.

I’ve got the 5.3 in a 2010 Tahoe and dash monitor shows about 14-15 mpg. It is what it is. Don’t care.

Completely normal. We average 15mpg on the highway and 11mpg around town in an ESV. I get 13mpg mixed in my 08.

2012 Denali XL wife gets about 14-15 around town and 16-17 highway @80MPH. Just finished a 1,500 mile trek to Utah and back (from CA Bay Area) and averaged about 15 @85-90MPH. All stock except a bigger tranny cooler for towing occasionally, 175K miles and runs great.
