Please explain because this does not make sense.
I've never seen a non GDI gas powered vehicle turn oil black under normal conditions unless there was a reason. Off the top of my head, my old 78 Chevy truck when I was a kid, the choke was so out of wack it would flood itself on warmup to the point of fouling the plugs, oil turned black. One year the fuel pump diaphragm dumped a bunch of gas into the oil. Level went way up and looked black. Same truck, now parked and gets ran once every few years. I changed the oil around 8 years ago and it looks like new still even after some run time and 8 years of sitting.
79 Chevy 305 had a bad camshaft, misfiring on one cylinder. Oil was always black.
Customers car coming though the Pennzoil, if they went way over their oil changes, oil is black, sludge in the valve cover, sometimes engine noise, as soon as you change it, it would turn black again. If we liked the person, sometimes we'd do a double oil change.
Anything well maintained, it stays relatively clean up until the point that it needs to be changed. I have no idea what healthy vehicles you've seen that turn oil black that quickly. I've been around a lot of cars and paid attention to oil, done a lot of oil changes. That has never been my experience.
It may look black once drained into the pan, but on the stick you should at least be able to see through it.
