Well, FR-S10, I think what we have here is a "old school" vs. "new school" (or old, new engines vs, new, new engines) thing working.
(that outta get ol
dttaz all twisted up ....
.)
Back in the day, when engines were machined, lots of metal shavings were present with a new engine, thus many felt it was a good practice to flush out the "break in oil" after a thousand or so miles ..... to get the shavings out of the oil and most that settled in the oil pan.
It's my understanding that modern engines are machined closer and produce much less by-products of the parts getting used to working together. Thus, a longer interval before the first oil change.
The use of synthetic oil extends the interval even longer.
So, ya wanna be old school or new school ...
