Excessively and 100% sure unnecessary soon. 8252mi on it right now. Got changed at 80, 1000,
3000ish (edit - 2434mi), and at least 3 more times that I can’t recall off the top of my head in between. Part of my post track day inspection I ask my local 86 specialty shop to do alignment when they inspect all the aftermarket parts prior to tech sign-off. Sometimes I forget to ask them and have my tech at dealer sign off. Then it goes to dealer for oil change and tyre rotation. I have absolutely no doubt Blackstone would tell me I’m being silly but it makes me feel warm and fuzzy

Lots of free oil changes + relatively cheap insurance plus I take track inspections pretty seriously. I do not want to be responsible for causing an accident due to negligence on my part.
Edit: Duh, I forgot most of these are in the app, does not register work done by my local 86 shop so this is not 100% complete and accurate, I've slept since then
10 Feb - 2mi off truck; check in, left dealer with 6mi on odometer
26 Feb - 569 mi; first registered oil change at dealership '80mi oil change was at local 86 shop if i recall correctly so not in recorded in app', radio disconnect 'CarPlay' issue initially brought up if I recall, I may have brought this up sooner
03 Mar - 746 mi; radio issue 'CarPlay' escalated to Toyota corporate via service manager due to no improvement, spoiler install, few other msc items; received HomeKit long life battery mirror and installed myself (date may be off on mirror by a few weeks)
~2ish week of Mar - 1K oil change done by third party since falls outside of my free oil change agreement
7 Apr - 2434 mi; oil change and rotation , rear diff fluid change; could have swore I did rear diff sooner than this 'app does not appear to be 100% accurate'; in between this and next visit had almost 100% of all aftermarket parts installed 'rim/tyre installationat dealer' and camber adjustment at said 86 tuning shop 'they do superb work btw, kudos to my dealer as well they have been phenomenal'; tech inspection and sign-off by mechanic

1 May - 27 May; Tech inspection prior to NCM by either dealer or 86 shop, I cannot remember which one

There's definitely a few items missing but this is the bulk of it without spending time going through emails after email. When zits are fixed on front bumper and prior/post surgery will have another oil change prior to Sept trip. ~5K trip overall so planning on oil change once I'm there then another one when I return home.
These records above are just what shows up in my app, not 100% of all work maintenance and inspections done so far. Just what is easily accessible.
Going forward, I plan on sticking with oil changes approx. 2500mi since this falls within severe duty and tyre rotation/balance every other oil change. Had to postpone having the 4 zits on the front fixed 1 Aug due to cheque running behind from insurance and juggling surgery and other misc fun things happening. Was supposed to have at minimum 2 additional HPDEs but have cancelled remainder for this year. Not sure how recovery time will be and do not want to occupy a novice spot in HPDE that someone can use.
Tl;dr, I'm kind of a maintenance nut and do not want Toyota corporate to point to me neglecting oil changes and frequent oil level checks as a source of engine failure should the worst happen. This car has every single record of every single thing ever done to it as of 6mi of ownership.
