Fubex DEO 5W-40 CI-4 Diesel Engine Oil

The DEO 5W 40 Cl-4 diesel engine oil is a multi viscosity oil as it has lesss vviscosity at low temperatures (as indicated by the 5W) but it thickens as temperature increases. At high temperatures it has the viscosity rating of ‘40’ which is pretty high. Therefore the ZEXER 5W 40 Cl-4 fully synthetic diesel engine oil is a multi viscosity engine oil.

5W-40 is cl-4 is a unique grade as it is a multi viscosity grade. The oils in this grade, such as the  DEO 5W 40 Cl-4 diesel engine oil have low viscosity in low temperatures but thicken up as temperatures increase. This means that these oils perform well in both hot and cold temperatures. The Cl-4 specification tests oils in a vast number of parameters such as Emission control, wear protection, soot handling, oxidation and thermal stability and compatibility with diesel engines, setting it aside from other specifications.

The DEO 5W 40 Cl-4 fully synthetic diesel engine oil  is applicable to nearly all vehicles, including gasoline and diesel engines, turbo as well as four valve. However, it still does not 100% apply to all types, so make sure to consult your user manual before using.

The The DEO 5W 40 Cl-4 synthetic diesel engine oil has a low viscosity at low temperatures so provides a cold start, and a high viscosity at high temperatures so provides a thick film. Therefore it is very much suitable for extreme weather conditions.
