Motor gasoline is a refined fuel specifically designed for spark-ignition internal combustion engines commonly found in cars, motorcycles, and light equipment. It is produced through the distillation and processing of crude oil, followed by blending various hydrocarbon components and additives to meet strict performance, efficiency, and emission standards.

A key performance measure of motor gasoline is its Research Octane Number (RON), which reflects the fuel’s ability to resist knocking or detonation during combustion. Engines with higher compression ratios require gasoline with higher octane ratings to operate efficiently and safely. Modern gasoline formulations also include additives that enhance combustion quality, reduce engine deposits, prevent corrosion, and support cleaner emissions.

Common RON grades available include:

• RON-100 – premium high-performance fuel for advanced, high-compression engines.

• RON-98 – high-octane fuel offering excellent engine performance and efficiency.

• RON-95 – widely used mid-high octane fuel suitable for most modern vehicles.

• RON-92 – standard gasoline for general-purpose engines with moderate compression.

• RON-80 – lower octane fuel typically used in older or low-compression engines.

Overall, motor gasoline serves as a vital energy source for transportation, offering multiple octane grades to accommodate diverse engine designs and performance needs.
