Frequently Asked Questions
What are the primary applications of API CF-4 diesel engine oil?
API CF-4 engine oil is primarily designed for high-speed, four-stroke, heavy-duty diesel engines. It is ideal for turbocharged and naturally aspirated engines used in commercial trucks, buses, agricultural machinery, construction equipment, and mining operations.
How does Longhai API CF-4 oil control engine deposits at high temperatures?
Our oil formulation features advanced high-temperature detergents and dispersants that actively prevent the formation of carbon deposits, sludge, and varnish on critical engine components like pistons, cylinder liners, and turbochargers under extreme operational heat.
Why is TBN retention important for heavy-duty diesel engines?
Total Base Number (TBN) retention indicates the oil's ability to neutralize acidic combustion byproducts. Longhai API CF-4 maintains a robust TBN over extended drain intervals, protecting engine components from corrosive wear, especially when using high-sulfur diesel fuels.
How does this oil handle soot and prevent viscosity increase?
The oil features advanced soot dispersancy technology. It encapsulates soot particles to keep them finely dispersed in the oil, preventing them from agglomerating into larger abrasive structures that cause oil thickening, filter plugging, and engine wear.
Is Longhai API CF-4 diesel engine oil compatible with modern emission control systems?
Yes, our low-sulfur, eco-friendly formulation is engineered to be compatible with exhaust aftertreatment systems such as Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR) systems, helping fleets meet strict emissions standards.
