Overview
Automotive Gas Oil (AGO) is a middle-distillate petroleum product used primarily as fuel in diesel engines for vehicles, trucks, buses, and industrial machinery. Unlike heavy residual fuels, AGO is a lighter, cleaner-burning diesel fraction that provides reliable performance across transport and industrial applications.

Technical Characteristics

• Grade: Automotive Gas Oil (diesel-type distillate fuel)
• Appearance: Clear to light yellow liquid
• Density @ 15°C: 0.820–0.870 kg/L
• Cetane Number: Minimum 45–51 (depending on regional standard)
• Sulfur Content:
  • Low Sulfur AGO (LSAGO): ≤ 0.25% by weight
  • Ultra-Low Sulfur AGO (ULSAGO): ≤ 0.05% by weight (50 ppm)
• Flash Point: Minimum 55°C (ASTM D93 / EN ISO 2719)
• Viscosity @ 40°C: 2.0–4.5 mm²/s
• Pour Point: −6°C to −18°C depending on grade
• Cold Filter Plugging Point (CFPP): Regional (−5°C to −20°C typical)
• Ash Content: ≤ 0.01% by mass

Specifications & Standards

• Conforms to ASTM D975, ISO 8217, and EN 590 (regional variants)
• Meets emission standards where regulated (Euro III–VI equivalents depending on sulfur grade)

Applications

• Automotive: Fuel for diesel-powered passenger cars, buses, and light commercial vehicles
• Transport & Logistics: Widely used in freight trucks and long-haul vehicles
• Industrial & Construction: Fuel for heavy-duty engines, off-road equipment, and agricultural machinery
• Marine (Inland Vessels): Suitable for small vessels requiring middle distillates

Performance Advantages

• Versatility: Can be used across road, industrial, and light marine applications
• Lower Sulfur Grades: Reduce particulate and sulfur oxide emissions, compatible with emission-control technologies
• Good Ignition Quality: Ensures efficient combustion in compression-ignition engines
• Seasonal Adaptability: Available in winterized grades for cold climate operation

Handling & Storage

• Must be stored in clean, sealed tanks free from water and microbial contamination
• Recommended to keep storage below 40°C to avoid oxidation and fuel degradation
• Requires regular filtration before end-use to maintain fuel cleanliness

Compliance & Testing

• Verified against ASTM, EN, and ISO standards for cetane number, sulfur content, and lubricity
• Typically accompanied by third-party Quality & Quantity (Q&Q) inspection (e.g., SGS, CIQ, Intertek)
