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?
