There's a lot of stuff "ticking." The trick is knowing what is bad.
Cut open your oil filter, especially after the first oil change. Tony sends his oil for analysis, me likey.
It wouldn't hurt to run 5W30 oil in the warm weather. As previously stated, I prefer Full synthetic oil.
He referenced piston slap. Pistons are not perfectly round when cold. As the engine warms, they swell, becoming rounder. A little piston slap when cold is not terrible since the skirts are usually coated or machined to be "slippy;" as long as it quiets down when the engine reaches operating temperature.
I had a Subaru that had cold piston slap from day one and we drove it 14 years, before the body returned to mother earth.
In summary; DI pumps, injectors, cam phasers, mechanical noises, OK. Metal in the oil, low oil pressure, high oil consumption, loud noises that don't go away; cause for concern. Remember, two engines in one!

In my defense, I was left unsupervised.
