Gas milage

What do you average when you are

Ok that is very impressive , but how about actual highway speeds ? At that speed Big Rigs would be walking around me and telling me i'm #1.

I average around 20.1 @75-80mph or 21.2 @70-73mph for road trips between TX/OK. and currently have 18.2 for daily driving of mixed 60% city.

2015 leveled Crew 4x4, 5.3 with 3.42's

4x4 trucks use a little more gas. Here in arkansas the speed limit is 70mph but the big rigs speed limit is 65mph. I've made several trips on the interstate with almost identical mpg results unless having a bad head wind. Remember my truck is a 2wd. Most of the trucks I see on here are 4wd. 4wd with a lift & bigger tires kills gas mileage.

I'm at 13,500 miles since November and I've been averaging 14-16mpg. I reset my trip computer every fill up. I do equal amounts city and highway driving. Typical freeway speeds of 70-80mph. 2015 Sierra 6.2l, crew cab, 6.5' bed, 2wd, 8 speed trans, 2.5" leveling kit. I always use 91 octane. I live in California and use my a/c frequently.
