Gas or gasoline is the most common automobile fuel and is used all over the world to power cars, motorcycles, scooters, boats and other machinery. Gas are of three types based on their octane levels - Regular gas has the lowest octane level of 87, Mid-grade gas has an octane level of 89 and Premium gas has the highest octane levels from 91 to 94.


Gasoline, commonly known as gas, stands as the most prevalent fuel for automobiles worldwide. Its ubiquitous usage extends to powering a diverse range of vehicles, including cars, motorcycles, scooters, boats, and various machinery, playing a fundamental role in global transportation and industry.

Gasoline comes in three primary types, classified based on their octane levels, a measure of the fuel's resistance to premature combustion:

1. **Regular Gas:** With the lowest octane level among the three, regular gasoline typically carries a rating of 87. Suited for many standard vehicles, it strikes a balance between performance and cost.

2. **Mid-Grade Gas:** Positioned between regular and premium, mid-grade gasoline features an octane level of 89. This option caters to vehicles that may benefit from a slightly higher octane rating to optimize performance.

3. **Premium Gas:** Boasting the highest octane levels, typically ranging from 91 to 94, premium gasoline is designed for high-performance or luxury vehicles. These vehicles demand superior combustion control and efficiency.

The octane rating serves as an indicator of a fuel's ability to resist engine knocking or pinging. While regular gas is suitable for many vehicles, those with high-performance engines may require mid-grade or premium gasoline for optimal efficiency and to prevent potential engine issues.

The availability of different gasoline grades offers consumers flexibility in choosing the fuel that aligns with their vehicle's specifications and performance requirements.
