Premium Gasoline is a high-octane, highly refined petroleum fuel engineered for modern internal combustion engines operating under high compression ratios, turbocharging, or advanced ignition timing. It provides superior knock resistance, enhanced combustion efficiency, reduced engine deposits, and excellent thermal stability.
Produced through advanced refinery processes such as catalytic reforming, isomerization, and alkylation, Premium Gasoline is blended with precision additive packages to meet stringent international fuel quality standards including Euro VI, BS-VI, ASTM, and EN.
Key Characteristics
High octane rating (typically 91–94 RON or higher)
Enhanced detergent additives for cleaner engines
Improved combustion quality with lower deposits
Superior thermal stability under extreme conditions
Reduced engine wear through friction-reducing additives
Chemical Composition & Refining Background
Iso-paraffins for improved octane and stability
Controlled aromatic content for emissions compliance
Low olefin levels to reduce gum formation
Optional oxygenates (ethanol or MTBE, region-dependent)
