I recently bought a Echo PB-755 Backpack Blower to blow leaves in my
yard.

I am very puzzled by it. It is a 2 stroke engine. Takes 50:1 oil.

There is no separate tank/port/opening for engine oil.

The manual has not a single word mention of engine oil (like 10w30 or
whatever).

So, all indications are that this engine needs no oil.

I can hardly believe this as all gas engines I have seen so far needed
engine oil.

Is my conclusion that the engine needs no oil, correct?

No separate oil other than the oil mix in the gas.
The oil-gas mix lubricates all internal parts.
