Iff you plan on your first long oil change interval, check your oil level at least every 1000 miles.

Subaru made some engines that blew up before their first oil change.

At my son-in-law's dealer they had to test some of their new cars by filling them carefully and bringing them in again (I do not know how many miles) to check how much oil they burned.

My son-in-law, the top tech at the dealer had to re-ring several cars.

He won a reward from Subaru because he found a place to put a vice grip during reassembly because if one followed Subaru's instructions for reassembly the timing chain was noisy!
