What does regular gasoline typically have as an octane rating range?

Regular gasoline typically has an octane rating range from 85 to less than 88. The octane rating measures a fuel's ability to resist knocking or pinging during combustion, which is crucial for engine performance. Regular gasoline is designed for use in most vehicles, particularly those with lower compression engines that do not require high-octane fuel.

The octane rating can vary slightly by region and manufacturer, but generally, the range for regular gasoline falls within those values. Understanding the octane rating is important for ensuring the fuel used in an engine is appropriate for the manufacturer's specifications, optimizing performance, and preventing engine damage. Using a fuel with too low an octane rating can lead to engine knocking, which harms engine efficiency and longevity.
