I have driven Chevys all my life.
They easily go 250-300,000 miles.
No burning oil, no failed transmissions.
Service properly engine oil & tans fluid.
When the transmission get to be high milage DO NOT FLUSH, only regular fluid & filter change.
At 190,000 l had to replace the throttle body & belt tensioner and alternator.
My recent 5.3 needed a rear main seal at that 198,000 mark. Still, it doesn't burn oil. So at most l put 12-1400 into it in repairs. RMS is the only repair l had done by a garage. I also put american rotors & brake pads on it.
Lasty, it appears l need Lower bj's now at 208,000 miles.
Run's like a top! 16 city. 25-28 highway on clean roads.
