Diesel engine oil series

What is Diesel Engine Oil?

Engineered for Heavy Loads & Extreme Conditions

Diesel Engine Oil is a specialized lubricant formulated to withstand the high compression ratios, soot contamination, and extended operation cycles of diesel engines. Its advanced additives combat acidic byproducts from combustion, prevent piston ring deposits, and protect turbochargers under extreme heat. Unlike gasoline engine oils, diesel-specific formulas feature:

• Higher TBN (Total Base Number): Neutralizes acids for 2-3x longer drain intervals (up to 60,000 miles in highway trucks).

• Low SAPS (Sulphated Ash, Phosphorus, Sulfur): Compatible with DPF/SCR systems to meet Euro VI/EPA Tier 4 emissions standards.

• Shear-stable viscosity: Maintains film strength under heavy loads (e.g. towing, mining).

Trusted by fleet managers and OEMs, our diesel oils are rigorously tested to API CK-4, JASO DH-2, and CAT ECF-3 specifications.
