I've had several 5.3s. A great engine. I now have a 3.0. Best engine yet. 30MPG. The 460lbs of torque make it feel like youi're driving a big block Chevelle. Only extra expense I see is changing the fuel filter every 30,000 miles. After driving the 3.0 if I had a 5.3 I would be trading soon.

I'm kinda late to the party but just purchased a 2020 Silverado with the 3.0. Couldn't be happier. I've had temps in the teens and it takes about two seconds for it to fire up. Mileage between 27 and 33 depending on speed and road. Fantastic power in the range where you need it. As far as the oil pump belt, It's supposed to last at least 150,000 miles. Harley uses drive belts to pull 800 pounds around and they last forever so I doubt turning an oil pump is much strain. And if you do have to replace it at 150,000 probably still an easier job than pulling the front of the motor to replace a timing belt or chain. I expect some growing pains with it being a new engine but so far it's smooth sailing. I traded in a 2019 Ram that had been in the shop 14 times in 12 months so.........
