Blaming the EGR for anything and everything is currently a "thing" on Priuschat.

The only vehicles I've ever seen have pcv problems RELIGIOUSLY are all Chevrolet car profile v8s. Those things need a 1" ID pcv system at minimum to not suck oil. *shakes head*

The EGR recirculates carbon in to the intake. That can be an abrasive.

3D printers that print carbonfiber filament have rapid wear of the nozzle.

Not saying this is a cause, just relevant things that pop in to my mind.

I never thought about that, great point! I blocked off my Civic's EGR because I didn't want my intake manifold getting full of soot and heat soaking from the hot exhaust. I can't really say that I noticed a difference in the way it runs or a difference in gas mileage, but YMMV (no pun intended)

I wish it was more abrasive because I've noticed a lot of people have clogged egr coolers lol

Alright just changed the oil in the Prius. 172k. I put in 5 quarts 9000 miles ago and 2.1 quarts came out. So the car consumed 2.9 quarts. That's similar to 1.6 quarts every 5000 miles. Just changed the oil with a can of 6 cylinder engine restorer and some more 0W-20 oil. So 5 quarts total goes back in and we will see what comes out.
Update:
YUP THE PIG IS SUCKING OIL!
Air filter is clean after 80k miles now. Top side of the throttle body is clean. Back side of the throttle body was oily. Got a screw drive to prop it open... There is literally a reservoir of oil in the intake.
Time to go to Prius Chat and complain.
