Among them is the mechanical setup, geometrical configuration, compression ratio, and even the environmental conditions where the vehicle is running. Know that the bigger the number for the octane rating, the better that fuel is at resisting knocking or pinging when the engine is running. The vehicle manufacturer, in this case Toyota, is the one who makes the recommendation on fuel octane rating.
According to Toyota, the Prius needs to be refueled using unleaded gasoline with an octane rating of Meeting the Prius octane rating is important, if you want the hybrid car to run as it was designed. In some situations, you might not be able to purchase anything with an octane rating of 87, forcing you to go with 89 or higher.
Certain vehicles need gas with a higher octane rating. This could be from using a high-compression engine or advanced electronic controls. With those cars, you can use a lower octane fuel, but it will negatively impact power output and fuel economy. Now that you know what kind of fuel your Toyota Prius uses, you can make more confident choices at the gas pump. Get a life.

In my previous car before my Prius , I ran three tank full of Costco, and then three tank full of There was enough difference in mileage to make the 76 gas actually cheaper than Costco.
Earlier, we laid out what will happen if the wrong fuel is put in a vehicle that requires premium. But what if the reverse happens? It will make for a more expensive stop for gas but no other problems. In fact, most vehicles employ a fuel system that will change certain settings to make it run on almost any fuel.
