No, it’s not. One of my best friends is a professional mechanic and he stresses oil changes over everything. I have heard the exact same thing from diesel specialists that I’ve paid to work on my vehicles.

Engine oil is the buffer between all of the moving components in your motor. As the move (thousands of times per minute) they all rub. When metals rub they shave microscopic pieces off of each. Your oil becomes filled with huge amounts of hard and abrasive materials. The oil also gets degraded from micro plastics (gaskets degrading) and hydrocarbons (ICE by products).

No amount of efficiency upgrades stop or mitigate these processes.
