2000 5.3L with 145,000kms

started up my truck to move it in to the driveway this morning and it started fine. parked it, turned it off, changed my mind to move it back in the garage, upon start up had very rough idle, lights dimming etc for around 10 seconds. put it in drive, still very rough, turned off. waited 5 seconds tried again, same thing. tried 3 more times same thing? feels like fuel pump. no check engine lights came on.

  Good to see all of the smart logical early retirees.

  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.

  Cost me just under $3k to fill all 3 of my #2 tanks. That place was more than .50 cents a gallon cheaper than everyone else. I'll be set for a while.
