Recommended 100k Mile Maintenance ?

start with the maintenance schedule that came with the car, then add tranny fluid change

 

I'd second the transaxle fluid change. I'd really recommend to do it about 90K back, but no time like the present.

Some more:

1. Do a full brake inspection. Long overdue.

2. A brake fluid change would be a good idea too.

3. Throttle body cleaning.

And then, depending on how long you intend to keep the car, and how deep you want to get into it:

4. Exhaust gas recirculation system inspection/clean. Start with the pipe, easiest, get some idea of the rest.

5. Intake manifold inspection/clean.

6.. Oil Catch Can install on the Positive Crankcase Ventilation circuit.

Watch @NutzAboutBolts videos, pinned at top of 3rd gen maintenance forum, lots of insights and tips.

pads aren't difficult, but there are some precautions on a prius that other vehicles don't have.

such as, the brakes are electric, so if you don't disconnect the 12v, and open the drivers door, the pistons will shoot out, and then you'll be changing the brake fluid too.

best to watch a how to video if you can find one.

otoh, prius pads can last a long time, so measure the thickness, don't just change them for no reason.

 

it will be interesting to see how clogged your egr is. you have the upgraded pistons and rings, and we don't see many 15's with 100k already.

 

My 14 has 95000 so I’m right behind them. Mine only has the newer rings right? Or is it the pistons?


iPhone ?

 

rings, correct. time to take a peek inside

 

right behind you at almost 90,000

 

Your model year being 2014, I believe just the revised pistons. I compiled this list querying replacement pistons and rings (for various years) at McGeorge Toyota Parts:



One thing puzzles me though: why McGeorge would not suggest the updated parts, regardless of year.

The technical service bulletin relating to excess oil consumption (attached) instructs to tear down the engine and replace the pistons and rings with the revised (2015 model year) parts. The implication there is that these pistons and rings are better, less prone to causing oil consumption down the road.

But it's not stated. I would think if you did the engine tear down and replaced piston and rings with the old numbers, it would also likely stop oil consumption, likely for the practical life time of the car.

Which leaves the question: are the new pistons and rings that much better? Maybe, but who knows. It'd be interesting to see side-by-side comparison pictures of them, measurements, any variations. Maybe the new rings spring out more? The piston oil draining channels are larger or more?

I started a thread with a poll: what year do you have and how's your oil consumption:

So far the preponderance of votes have been early years, no 2014, and two 2015's. Not enough of a sample to draw any conclusions I think. Feel free to vote btw, get a 2014 in the poll.

 

Just bought a 2014 with 88k

 

congrats and welcome!

same goes for you
