First oil change!
Exactly 4.3l of Rotella T6. Maybe placebo, but the engine sounds quieter. It'll need another change in about 8 years
Also topped off the coolant reservoir.
Hydro change at another time.
To the bolded, viscosity breakdown will lead to louder clacking so I don't think your ears are playing tricks on you.
On a related note, isn't it funny how good an oil change makes us feel?
