I like that, looks pretty secure, I remember 1960s/70s Fords had terminal lugs on the battery instead of round posts, they were secure too but, some cars had caps secured with a self tapper, a fail waiting to happen.
I always change oil and filter at 5k or yearly whichever comes first, these days it's yearly but, I'm talking much older than 2021.
my current car is a 25 year old Merc if, I went by the service indicator it would be much too long.
