My stock tailpipe is marked as T-409 stainless steel.

I am sure that the upper parts, at least to the catalysts, are partially stainless- the feds force the manufacturers to warranty emission hardware for ten years or 100,000 miles-

  So using that analogy. Honda,Toyota, VW and others go extended. All my Hondas at 5K miles are at 50 percent with oil changes. My Camry I bought new my Grandaughter now drives gets 10K oil changes. All mentioned vehicles are past 100k miles. Most past 150K. Two at 170K. I’m the only one who checks oil. The only one who changes early. When they visit I check their oil, tires etc. if they were to use oil I would swap out with them. So I know they wouldn’t run dry. They don’t use oil according to the dipstick. One 2010 Mazda 3 we found really cheap another grand daughter drives. It’s getting near 180K no oil usage. That’s again is according the dipstick. I can’t make it any clearer.

  My question(s) are direct to this point, with no insult intended, could the dipstick not be showing an amount of loss comparable to what I see by measuring the volume drained at change time? I think most GM vehicles light comes on at max 7500 miles. I've also noted how much larger the oil pan capacity has grown - 10 quarts in my L5P, 9 in the Yukon, 10 in my previous Sierra. If 5 quarts in yesteryear could last 5k miles, the 10 should be doing 10k miles. That thought process isn't about oil life and degradation, but I'm alluding to maybe the capacity has grown to account for the 'loss' and prevent "seizing up all over the place" due to oil starvation.

  My interest isn't what is or isn't oil use, I'm interested in your measuring the use (or lack of) to compare to my own experience/measurements.
