Product Overview
AGREX REX Gold 15W40 is a high-performance, heavy-duty multigrade diesel engine oil formulated to meet the demanding requirements of emission-controlled engines. Combining premium Group II base oils with advanced shear-stable viscosity modifiers and specialized soot-dispersant detergents, REX Gold 15W40 shields critical engine components from wear, soot abrasion, and corrosive acids. It is highly recommended for modern BS-IV and BS-VI diesel vehicles operating with SCR, EGR, and DPF exhaust technologies.
Key Features & Benefits
- Soot & Sludge Dispersion: Actively binds combustion soot, preventing abrasive wear on valve guides and timing gears.
- Low-Ash Formulation: Minimizes ash deposits on Diesel Particulate Filters (DPFs), maintaining fuel efficiency.
- Corrosion & Acid Neutralization: Premium alkaline additives neutralize blow-by acids, protecting copper-lead bearings.
- Extended Drain Intervals: Excellent oxidative resistance keeps the oil from thickening, extending service drain intervals.
Applications & Suitability
- Commercial trucks, highway transport fleets, long-haul trailers, and passenger buses.
- Modern agricultural tractors (Swaraj, John Deere, Mahindra) operating under heavy loads.
- Heavy earthmoving, quarrying, and mining equipment (excavators, dumpers).
- Offshore marine engines and stationary diesel generator sets.
