I owned a 2011 Chevy…
I owned a 2011 Chevy Silverado 1500 with 240,000 miles on the 5.3 liter engine and original transmission before I traded it off on a brand new 2024 Chevy Silverado 2500HD. I loved that truck and it was still running great, good and strong, with no real issues. It still had good power, didn’t knock or rattle on acceleration, and didn’t burn oil. The only thing I did, was that around 190,000 miles I noticed a lower oil pressure at idle. On the advice of my GM certified auto tech son, I started running 10W-30 oil in it, instead of the 5W-30 it calls for. That solved the low oil pressure at idle issue and the truck was still running great at 240,000 miles.
