  • Gasoline

    Fuel for passenger cars and SUVs with gasoline engines. World-class detergents keep engines clean for smoother, quieter rides.

  • Diesel

    Fuel for diesel SUVs and passenger cars, as well as industrial/home boilers. Enables complete combustion for low noise, better economy, and high output.

  • Kerosene

    Fuel for residential and commercial/industrial boilers. Highly refined for cleanliness and excellent combustion performance.

  • Heavy Fuel Oil

    Used in ceramics, metal smelting, marine engines, and large boilers. Encompasses light/medium/heavy grades and is cost-effective with high calorific value.

  • LPG (Liquefied Petroleum Gas)

    A liquefied petroleum gas, classified into butane and propane. Butane is common for vehicle fuel and portable stoves; propane is a clean fuel widely used from homes and restaurants to industry.

  • Lubricants

    Oil-based substances that reduce friction and dissipate heat on moving surfaces—used across cars, ships, farm machinery, industrial equipment, and construction gear.

  • Asphalt

    The base material for asphalt concrete (asphalt + aggregate), produced during crude oil refining. It’s visco-elastic and temperature-dependent… Common refinery grades include AP-5 and AP-3.

  • Bunker Fuel

    A marine fuel for main propulsion engines, generators, and boilers. Produced from crude refining (HFO or MGO) and used in line with IMO and domestic regulations.

Heavy Fuel Oil

Cost-effective with high calorific value, widely used as a heat source for engines and boilers. Classified into B-A (light), LRFO (medium), and B-C (heavy) by properties; select the grade by application.

Category Applications
Light Fuel Oil (B-A) Ceramics, smelting, boilers, small marine engines
Medium Fuel Oil (LRFO) Boilers, medium marine engines
Heavy Fuel Oil (B-C) Large boilers, large marine engines

LPG

An eco-friendly energy enabling complete combustion thanks to outstanding cleanliness… divided into propane and butane.

Category Propane Butane
Usage Commonly used for household and restaurant cooking and heating applications. Used primarily for indoor cabinet heaters, automobile fuel, and portable gas stoves.
Vaporization Characteristics With a boiling point of –42°C, propane vaporizes easily even at low winter temperatures. Therefore, propane cylinders for household use can be stored and used outdoors during winter. With a boiling point of –0.5°C, butane does not vaporize well in cold temperatures. For this reason, butane must be used indoors (e.g., cabinet heaters) or with systems equipped with forced-vaporization mechanisms, such as automotive fuel systems.
√ Term Description: Boiling Point The temperature at which a liquid begins to boil as bubbles form both at the surface and within the liquid.

Premium Gasoline

Upgraded from regular gasoline to enhance acceleration, cleanliness, and fuel economy while protecting the engine.

  • RON 98 or higher

    Higher knock resistance than regular gasoline (RON 91–94), boosting power, protecting the engine, and improving ride quality.

  • Improved Acceleration

    Optimized parameters deliver sharper throttle response for noticeably quicker starts.

  • Cleaner Engine & Better Economy

    Extra detergents keep engines cleaner, improving mileage and reducing emissions.

Gasoline

SK Energy gasoline markedly improves engine protection and acceleration over conventional regular gasoline.

  • Clean-Up: Powerful Detergency

    Advanced detergents prevent intake-valve deposits, keep engines clean, and remove buildup—boosting power/economy and lowering emissions.

  • Drive-Up: Smoother, Quieter Ride

    Lowers required octane to reduce knock and ORI, improving engine durability and ride comfort.

  • Environment Clean-Up: Eco-Friendly

    Helps cut NOx and other pollutants for a cleaner environment.

Diesel

Our diesel enables complete combustion for quieter operation, better economy, and higher output.

  • Excellent Ignition Quality

    Optimized cetane characteristics for superior compression-ignition performance.

  • Balanced Viscosity & Lubricity

    Protects injection pumps and maintains cold-startability and flow at low temperatures.

  • Appropriate Distillation Profile

    Balanced volatility for efficient combustion without sacrificing lubricity.

Kerosene

Highly refined for clean combustion and low emissions—ideal for indoor heaters and home boilers.

  • Excellent Clarity (Color)

    Indicates refinement/contamination; slight discoloration may occur over long storage.

  • High Smoke Point

    Longer smoke-free flame length keeps indoor air more pleasant.

  • High Flash Point

    Higher temperature at vapor ignition enhances safety.

Lubricants

Lubricants reduce friction and dissipate heat, critically impacting equipment performance and life.

  • Optimal Lubrication & Wear Protection

    Forms a strong oil film that minimizes wear and maximizes efficiency and service life.

  • Stable Viscosity & Temperature Control

    Maintains proper viscosity across temperatures for reliable operation in varied conditions.

  • Outstanding Cleanliness & Corrosion Protection

    Disperses contaminants, prevents deposits, and protects metal surfaces from rust and corrosion.

Asphalt

Produced in refining and used as the base for asphalt concrete.

  • Exceptional Quality

    Warm-mix paving cuts fuel/energy 20–30%… Superphalt and PMA offer superior viscosity, elasticity, storage stability, and resistance to rutting, cracking, and stripping—ideal for heavy-duty structures.

  • Eco-Friendly

    Uses RAP for circularity and ESG; warm-mix reduces GHGs, odors, hazardous fumes, and time; certified for carbon reduction (2023).

  • Reliability

    2 million tons/year capacity and nationwide distribution ensure stable supply across AP-5, Premium Asphalt, PMA, and more.

Bunker Fuel

With inherent viscosity and high heating value, it’s suited for long voyages and powers large vessels.

  • Low-Sulfur Fuel Oil (LSFO)

    ≤0.5% sulfur for IMO 2020 compliance, excellent stability/viscosity, and accepted worldwide.

  • Low-Sulfur Marine Gas Oil (LSMGO)

    ≤0.1% sulfur mandatory in ECAs; high-purity refining yields great cold-flow and ignition with clean burning.
