When a single engine airplane loses its engine, it becomes a glider. A glider is a flyable aircraft. Smart pilots of single engine aircraft take glider training (as have I) and know what to do when the engine quits: trim for best glide; find the best landing position given your altitude and the prevailing winds; maneuver to that spot with minimum bank, and land as slowly as possible.

When a multi-engine aircraft loses an engine, it becomes a barely manageable mess of asymmetric thrust. Plus multis are heavier, so their glide characteristics are worse. There’s a reason a multi engine license is harder to get than a single engine.
