it will not damage the engine.
all modern cars have knock sensors, and will retard timing if detonation is sensed. So youll get less power under hard acceleration, and perhaps worse fuel economy using a lower octane than the 91 the car is designed for.
using 94 will provide you no benefit and just waste money. 94 is only needed if your car is "tuned" or has the computer chip altered from factory settings to increase power.
