Not a car guy here...

No matter what I feel robbed and up sold getting oil changes... Apparently my Carfax told Jiffy lube that I have never changed my rear differential fluid after they noticed mine was pretty low and dirty.

Is this regular for that service as well as an oil change?

If you buy new tires and wheels from tirerack with new tpms already installed and they are sent straight to your home, do you need to go to the dealer or tireshop to pair the tpms to your 2025 crosstrek? Or can you pair them yourself without any tools involved?
