My 2007 Suburban with aluminum 5.3 used 2-3 litres of oil from 42,000km to 190,000km
I work in a diesel repair shop and see 700-900,000 km on Duramax and Cummins... I asked "how come"?
My boss says 15W40 Shell and a fuel filter eveytime..

I switched my Burb to reg 5W30 Dyno oil and always use Wix filters
I am not kidding, the Burb at 235,000km now uses 1/2 liter per 5000km now Never was a ticker

We just bought a 2006 5.3 L33 Z71 cab 1/2 from wind generator construction company 451,000km on it it been ticking a left side lifter for 2 weeks Dropped the oil today and added 15 W40 Shell and no more noise

Just saying
