So my parents are now seriously considering buying a 4th gen Prius and given that I have a oil drinker now, as well as reports of the 3rd gen 2010-2015 cars drinking oil, I kinda want to stave off the issue before it rears its head around the 120-150K mark. I can't steer them towards a thrifty non-hybrid or Tesla, it's out of my control. The 4th gen 2016-current cars still use the same 2ZR-FXE engine as the previous generation.
While I do think D1G2 oils are a great improvement in many areas, the Prius doesn't get a proper break-in, it's the nature of the beast. From what I've read, it's the rings coking that cause the oil consumption issue, same issue that plagues many Camrys and Corollas, as well as the Scion xA/xB, Echo and Yaris as they age.
My thought was to instead of a SN Plus/D1G2 oil in 0W-20, is to run a VW 509/BMW LL-14FE/MB 229.5 oil like M1 ESP X2 or Castrol Edge Professional 0W-20 to stave off the oil coking issues. Or don't loose sleep when they get the car and stick with D1G2 oils that are easier and cheaper to get and occasionally run Kreen or BG EPR before an oil change to keep the ring packs clean?
