In this video I am going to explain thoroughly the difference between premium unleaded gas and regular unleaded gas, I will explain what the octane rating on these fuels mean, whether it improves gas mileage or not, should you put regular gas in a car that recommends or requires premium gas, or should you put premium gas in a car that does not require it in order to save money on your gas bill. I will also explain what Engine Knock or Detonation and what Compression Ratio is and how it relates to whether or not you should use higher Octane Fuel.
