Just got my 2020 Silverado ltz with the 3.0 this past Saturday. I managed to find a used truck with 12000 miles on it. This thing has lots more pep than I thought it would have. On the ride home I started feathering the throttle to see what kind of mileage I could squeeze out of it and got 31 at one point. It also has more gadgets than any vehicle I ever owned, I’m still learning everything. So far I’m loving it.
