200,000 Mile Club

I can finally fill this out now! 206,000 miles currently on our 2015 Prius Four. We bought it new in July of 2015 and my wife used it up until March of 2024 and 173,000 miles. We got her a new Rav4 hybrid and I took over driving the Prius at that time.

1) Did you replace the HV battery pack? Do you maintain it? No it has the original HV battery. Only opened it up once at 173k to clean the fan.
2) Did you replace the 12v battery? No still original 12V battery
3) Did you replace the transaxle fluid? How often? Replaced at 173k, was completely black at that time. Changed again at 200k.
4) Did you replace the brake pads? Yes, on our 3rd set. My wife drove it like she stole it and I used autopart store pads and rotors the first time I changed them, they didn't hold up nearly as well as the oem pads/rotors which are now installed.
5) Your lifetime MPG (if available)? 40-45mpg in the winter, 50-55mpg in the summer
6) How often do you change your oil? Does your Prius consume oil? What brand / product did you use? Oil was changed by the dealer every 10k miles when my wife was driving it, now I change it every 5k with Mobil 1. I converted to a spin on filter as well. It does not consume any oil.
7) How about posting a picture of 200,000 miles on ODO?
8) Did you install an oil catch can? How often do you inspect or dump it? No occ installed
9) Have you cleaned the egr circuit? How frequently? Once @ 173k, planning to do about every 50k miles from now on
10) Any other maintenance? Engine and inverter coolant flushed twice, spark plugs changed twice, preemptively changed waterpump and pcv valve, installed updated intake manifold, been through a few sets of tires, brakes flushed a few times, engine air filter and cabin air filter changed as needed.
