How Does your Car's Gasoline Octane Level Affect your Car? | Automotive Parts Suppliers

All cars are composed of four-stroke gasoline engines. Of these four, the compression stroke is the one that condenses air and gas into a smaller volume in a cylinder before it is ignited by the spark plug. The amount compressed would then be called compression ratio. The gasoline octane level of a vehicle will tell how much compression the fuel needs before it can ignite. Usually the compression ratio is 8:1. Thru this ratio, one can accurately determine the octane rating of the gas that one must use in his or her car.

For a car engine to assume a high-performance level, it must have a high compression ratio and a high octane fuel. A high compression ratio involves a higher horsepower though the gasoline for the engine may cost higher as well. Making use of high octane gasoline prevents engine knocking as it tends to burn slower than low octane gasoline. Although it is important to note that this is not a fixed principle as certain cars can react differently to various types of gasoline. If your car is running on low octane gasoline running and has not experience engine knocking, then switching to high octane will not result to any significant advantages. It all really depends upon the build of the vehicle’s engine.
