TriboDyn TRI-EX² 15W-40 is a full synthetic heavy-duty diesel oil engineered with patented ceramic coating technology — the first oil to receive a United States Functional Patent in over 30 years. This advanced formulation actively bonds to metal surfaces, creating a self-lubricating ceramic film that reduces friction and wear under extreme pressure and heat. This technology is particularly valuable in diesel engines because it can help repair worn metal surfaces and reduce blow-by, a common issue that leads to power loss and increased oil consumption.
Independent testing has shown that TriboDyn formulations deliver measurable fuel mileage gains by dramatically reducing internal friction. Meeting or exceeding API CK-4 (the latest standard for diesel engines), API SN, and ACEA E9/E7/E4/E2 specifications, this 15W-40 oil is specifically designed for modern low-emission diesel engines equipped with EGR and DPF systems, while remaining fully backward compatible with older diesel engines.
It provides superior soot control, high detergency to keep pistons clean, and excellent TBN retention (10.0) for extended drain intervals. This oil is the ultimate choice for heavy-duty trucks, construction equipment, agricultural machinery, and mixed fleets.
