PETRO TRANS HD 40 (TBN 10)

API CF/SF Certified Heavy-Duty Engine Oil with High TBN for Extended Drain Intervals & Extreme Conditions

PETRO TRANS HD 40 (TBN 10) is a premium high-performance diesel engine oil engineered for heavy-duty applications, particularly in industrial and commercial vehicles operating under extreme conditions. Formulated to meet the rigorous demands of modern diesel engines equipped with turbochargers or superchargers, this oil delivers exceptional protection against oxidation, wear, and deposit formation. It is specifically designed for use in high-speed diesel engines that require robust lubrication performance under high loads, extended operating hours, and fluctuating temperatures.

This advanced engine oil features a balanced formulation with high Total Base Number (TBN) of 9–11 mg KOH/g, which ensures excellent neutralization of acidic byproducts generated during combustion—especially critical in engines running on low-quality fuels or biodiesel blends. The oil maintains outstanding viscosity stability across a wide temperature range, thanks to its superior Viscosity Index (≥100), ensuring reliable lubrication whether the engine is cold-starting or operating at peak heat. With a flash point above 200°C and pour point below -9°C, PETRO TRANS HD 40 remains safe, stable, and fluid even in harsh environments. Its detergent-dispersant additives effectively control sludge, varnish, and carbon deposits, keeping engine components clean and prolonging service life.
