Gasoil 5000ppm (5000) – Technical & Operational Overview
Product Definition
Gasoil 5000ppm is a mid-sulfur diesel fuel primarily deployed in off-road and industrial applications where ultra-low sulfur mandates do not apply. With sulfur content capped at 0.5% (5000ppm), it balances cost-efficiency with adequate performance for legacy equipment.
1. Key Specifications
| Parameter | Typical Value | Operational Significance |
|---|---|---|
| Sulfur Content | ≤5000 ppm | Exceeds modern road fuel limits |
| Flash Point | ≥52°C (125.6°F) | Meets basic safety requirements |
| Viscosity @40°C | 1.9–4.1 mm²/s | Suitable for mechanical injection |
| Cetane Index | ≥45 | Acceptable ignition quality |
| Density @15°C | 820–880 kg/m³ | Higher energy density than kerosene |
| Pour Point | −6°C to −24°C (seasonal) | Cold weather operability limits |
2. Primary Applications
Off-Road Equipment
-
Construction: Excavators, bulldozers, cranes
-
Agriculture: Tractors, harvesters, irrigation pumps
-
Mining: Haul trucks, drilling rigs
Stationary Combustion
-
Industrial boilers (steam/power generation)
-
Gas turbines (peaking power plants)
Niche Marine Use
-
Auxiliary engines on older vessels
-
Non-ECA zone operations
3. Regulatory & Environmental Context
Global Sulfur Standards
| Region | Permitted Use Cases |
|---|---|
| Developing Nations | Unrestricted off-road/industrial use |
| OECD Countries | Phased out (replaced by ULSD) |
Emission Profile
-
SOx Emissions: ~15x higher than 10ppm diesel
-
Particulate Matter: Increased sulfate particulates
-
Aftertreatment Impact: Incompatible with DPFs/SCR systems
4. Operational Considerations
Equipment Compatibility
-
Recommended For:
-
Pre-2000 diesel engines without exhaust treatment
-
Mechanical injection systems (non-common rail)
-
-
Prohibited For:
-
Tier 4 Final/Stage V engines
-
Urban vehicles subject to emission testing
-
Storage & Handling
-
Tank Requirements: Mild steel acceptable (sulfur inhibits microbial growth)
-
Fuel Stability: Antioxidants recommended for long-term storage
-
Filtration: 30-micron pre-filtration sufficient
5. Market Position & Alternatives
Cost Advantage
-
Typically 20–25% cheaper than 10ppm gasoil (reduced hydrotreating costs)
Transition Pressures
-
Replacement Technologies:
-
Bio-blended gasoil (B7-B20)
-
LNG for stationary power
-
Electrification of off-road fleets
