I've had both LS and LT engines. Never had had an issue with either. They get a bit more power out of LT with the direct injection. They upped the compression in the 6.2's (I had 2015 Silverado with a 6.2 and currently drive a 2020 Silverado with direct injection a 6.2) so it's get's better mileage. I haven't had a 5.3 with direct injection.
My 20 Silverado at 60 MPH will knock down 20-22 MPG no problem. Both 6.2's were are 4x4's.
