Why does it anger you that
Why does it anger you that other people have issues with a car that you don't? Go check the prius forums, the EGR issue is all over the place there.
You have a 2012, which didn't have as bad of an EGR issue because Toyota fixed the piston rings for 2012, causing less blowby, causing less oily exhaust, causing less oil going through the EGR cooler/valve. This resulted in less issues with the EGR. 2010-2011 is the years to watch out for.
