Regular (87 Octane) Gasoline is a light, highly refined petroleum fuel formulated for spark-ignition internal combustion engines operating under normal compression ratios. It is the most widely consumed gasoline grade globally and is optimized for everyday passenger cars, two-wheelers, light commercial vehicles, and small engines that do not require higher octane fuels.
The 87 octane rating (measured as Anti-Knock Index, AKI = (RON + MON)/2) represents the fuel’s ability to resist engine knocking or pre-ignition under standard operating conditions. This balance ensures reliable engine performance, acceptable fuel economy, and controlled emissions without the need for premium-grade fuel.
Refining & Production Process
1. Crude Oil Distillation: Gasoline-range hydrocarbons are separated during fractional distillation (boiling range approx. 30–200°C).
2. Secondary Refining Processes: To achieve the required octane level and performance, gasoline blending components are produced through:
- Catalytic Cracking: Converts heavy hydrocarbons into lighter gasoline fractions
- Catalytic Reforming: Raises octane by converting paraffins into aromatics and isoparaffins
- Isomerization: Enhances octane by rearranging molecular structures
- Alkylation: Produces high-octane, clean-burning blending components
3. Blending Operations: Final gasoline formulation includes:
- Reformate
- Alkylate
- Isomerate
- Cracked gasoline streams
- Optional ethanol blending (up to 10%) depending on regional fuel regulations
4. Quality Control Parameters: Each batch is tested and controlled for:
- Octane rating
- Vapor pressure
- Sulfur content
- Aromatic and olefin limits
- Distillation curve
- Density and flash point
Environmental & Regulatory Considerations
- Designed to meet BS-VI / Euro-VI / EPA fuel standards
- Low sulfur content to protect catalytic converters
- Reduced evaporative and tailpipe emissions
- Ethanol blending helps: Lower carbon monoxide emissions and reduce fossil fuel dependency
