I do, but when it drops cylinders, it starves those lifters for oil. I had a friend with a 2016 that had to have his rebuilt for this reason. He never went over or close on an oil change.

I am not sure weight oil used with 1st owner. I have used mostly synthetic blend oil since I bought the truck in 2014. I will report back what the cause of noise once I can figure it out. The responses have been helpful. Thanks

My friend always had his serviced at the chevy dealership, his brother was a mechanic there, His failed at 116 thousand, mine is 106 thousand right now, so we will see if the boost helps. I also have it seviced at the dealership in town.

He said when they fixed his that most fail at 116 thousand. They put in a bigger cam, and new valley and fixed the heads, or replaced them not sure. Then reprogrammed the ignition so it doesn't drop cylinders. It cost him some money but way cheaper than a new truck. He said it runds way better.

used too much when it was new

Put a can of STP in it.

It may have the wrong spark plugs and they've backed out a little, I had a mechanic tell me he's seen them blow clear out on that year and motor. It's worth a look.

Dump a can of seafoam in the crankcase and drive it around town for a bit. I also had an oil consumption issue which I believed was the rings from smoke on start up and idle so Ive ran 15-40 in it since. 100000 miles all good.
