There is no such thing as a 50k service.

Intervals:

45k, 52,500 k, 60k.

Dealerships are normally full of shit !

>Read what came with your car, do those services solely.<

Me personally:
My 2015 FRS (manual trans) has now 26k on it. So far I've done the oil and filters at 7500 mile intervals....and plan to always continue that, tire rotation at same interval as well.
The cabin and air filters I can check myself, clean them, or replace them as I see fit. And certainly I can replace washer fluid, wiper refills.
Honestly, I'm not gonna do much of anything else till it needs spark plugs or coolant change...whenever the book, my book states it should be done.
Looking now: Spark plugs at 60k, coolant at 137,500 mi...after I'm dead for sure.
Brake pads: whenever I rotate tires, I'll look at them.
Battery fluid level: check once in a while...yearly, close enough.
I most likely won't ever change brake fluid, trans fluid, or diff fluid...let the next owner deal with that. Who's gonna know but me...LOL.
Former Auto Tech here.
The car is Made in Japan...so give her only what she begs for, and she'll do just fine.

Nothing, I mean it, has gone wrong so far with my car. Zero warranty claims so far.

Thank you again for giving me the privilege of serving you. If you have any questions or need further assistance, please don't hesitate to ask...LMFAO !
