The 5W-20 simply refers to the viscosity rating of the The ZEXER 5W 20 Cl-4 diesel engine oil . The ‘’5W” tells us that it is has low viscosity at low temperatures and the “20” shows that the oil retains it’s fluidity at high temperatures. Meaning it provides a great cold start and lubricates easily.

The Cl-4 specification for any diesel engine oil, including the ZEXER 5W 20 Cl-4 means that the oil was tested for a wide range of lubricant qualities such as Emission control, wear protection, soot handling, oxidation and thermal stability and compatibility with diesel engines. Therefore any Engine oil that meets the  Cl-4 specification qualifies in all these parameters at once.

The dual compatibility of the ZEXER 5W 20 Cl-4 as both a gasoline engine oil and a synthetic diesel engine oil sets it aside from other oils. In addition to its features such as advanced wear protection, oxidation resistance, engine cleanliness and soot handling.

Yes, The ZEXER 5W 20 Cl-4 diesel engine oil also works as a gasoline engine oil and hence can be used in gas vehicles.

The  ZEXER 5W 20 Cl-4 diesel engine oil protects your engine against wear and corrosion and prevents sludge and soot buildup all while reducing overall friction. Therefore this oil indeed extends your engine life.

The  ZEXER 5W 20 Cl-4 diesel engine oil is a low viscosity oil and as such is not recommended for high performance vehicles.

The   ZEXER 5W 20 Cl-4 diesel engine oil can operate in temperatures as low as -35℃ to temperatures higher than 100℃.
