#Octane Rating

Octane Ratings basically tell how much the fuel can be compressed before it spontaneously ignites. To explain further, an octane rating is the measurement of KNOCK RESISTANCE of a fuel. How would you know which octane rating is for your vehicle? For starters, powerful vehicles that have high-performance engines can compress the fuel-air mixture more than normal engines do which is why they need gasoline with a higher octane rating. Prevention of knocking in high-performance cars is the only reason to purchase fuel with a higher octane rating. As for most modern vehicles, they usually do not require higher octane fuels unless specifically expressed in your owner’s manual (which you should actually read) that says explicitly if it’s REQUIRED or RECOMMENDED. Does a higher octane rating mean more power? This is one of the most common misconceptions that come with octane ratings.
