Does octane rating really affect how my car runs?
It depends on your car. Indeed cars are designed for a certain octane rating. If you use lower octane rating than that one that your car allows, your car performance will be affected.

The main point to remember is that when your engine knocks or pings during acceleration, your octane is too low. The ideal octane for your car is the lowest grade you can give it without encountering the dreaded knock and ping. Otherwise if you use a higher octane rating you won´t get any benefit.


Gasoline is a mixture of 20 to 30 different fuels, octane being the heaviest fuel in unleaded gas. A gasoline's octane rating is simply the percentage of octane fuel it contains. High octane gas is better for summer driving because it won't evaporate quickly; low octane gas is used in winter because it ignites easily.
