I’d love to read about how emissions / fuel economy is causing the oiling problems. Any articles?

Would putting an aftermarket oil pump in these modern engines protect them or is it a deeper design issue?

They spec the thinnest stuff they can get away with to add .0001mpg. Multiply that by all the Chevy 1500s GM makes or F150s Ford makes and you see the draw.

Sometimes it turns out that the thinnest stuff they can get away with just not quite thick enough at the margins or in transient conditions. And of course they stretch out the oil change interval to reduce on-paper TCO as well which doesn't help.

You can mitigate this with thicker oil (what GM did for the recall) by can go too far and create other oiling issues because thick oil drains back slower and going to some super high spec 0-W-<whatever> Euro oil may cause other problems related to soot and sludge so there's no silver bullet.

The "safe" advice most people give out is to use whatever the <nation with no emissions or fuel economy rules> version of your owners manual says to use for oil.

And if you have a high strung turbo engine you ought to take your oil change intervals seriously.
