Recently we purchased a 2023 Tahoe high country with a 6.2 new (had I think 3 miles on it when they literally drove it out of the showroom for us).

Considering this is a direct injection engine I decided to put an oil catch can on it at around 500 miles. Here's what that oil catch can caught after only 3000 miles of use.

All that nasty, including whatever those solids are that stayed in the bottom, would've ended up glued to the back of the intake valves, or stuck along the intake port after mixing with EGR gases, if not for the catch can.

I'm now a believer in the need for oil catch cans on GDI engines (probably wouldn't hurt on port injected engines either, but NEEDED on direct injected ones).

Keep track of the amount of oil caught in the catch can, and the amount of miles driven. I empty my catch can and record its volume whenever I change the motor oil. I average about 0.9 fl. oz. of oil in the catch can for every 1000 miles driven.

I was surprised to find my catch can full after only 3,474 at the first check since I installed it. I imagine it accumulated even more although probably drank it away anyways considering it was full.

How much of that 3,400 miles was above 3500 rpms giddy ups?

When my wife drive my truck, it uses oil. When I drive it, no oil of consequence is used up. I get 3 mpg or better than she does generally.

I drive mildly. Not one full throttle in that time period. RPM wise, I don't know. Mostly suburban/city driving with some mixed highway here and here. However, my oil level is never low. I check the oil regularly.

Just curious, what weight oil do you run? Also what engine and how many miles?

That does seem excessive to me for only 3500-ish miles.
