Over time using premium gasoline in a car that doesn’t require it can lead to engine knock. Engine knock is a knocking or pinging sound that happens when the air-fuel mixture in the cylinders is detonating too early.

In addition to engine knock using premium gasoline in a car that doesn’t require it can also lead to decreased fuel economy. That’s because the higher octane rating of premium gasoline means that it takes more energy to ignite the fuel.

So if you’re using premium gasoline in a car that doesn’t require it you’re essentially wasting money.
