My fresh cammed 6.2 is showing worse than the 5.3 so far but its not tuned yet.

I have a 2013 Chevy Tahoe 5.3L...what should i expect to average for mpg? Mostly city driving. I try to baby it as much as possible.

When I was driving my XL with all-terrain tires for Uber, it would average 15 to 16 mpg. About 2 years ago I took the average of all the GMT900 wagons with the 5.3 on Fuelly and learned that they ALL average 14.3 MPG.




Here's my truck's chart over the last three years on all types and brands of fuel:






If you burning 87, you're going to get crummy gas mileage.

"If you burning 87, you're going to get crummy gas mileage."

Very true

I baby it and get 13 for my daily driving. I probably exceed 35 mph for only 10 miles per 100 miles. On a trip over the mountains, I've never gotten better than 18.

Lol the MPG in my 6.2 is abysmal, but it does have a cam. I lost at least 2 mpg from the 5.3, maybe even worse. I also did ZL1 torque converter, that probably made it worse too.

my 2019 Suburban Premier Plus (6.2l) has achieved 23mpg on freeway trips and avgs 18.6 mpg, if its all in town driving. Snow tires reduce hi way mpg to a max of 20.

My truck's mpgs are worse at 35 and below. At 35, she's in 5th gear tops.
