Why is 5W-40 CI-4 considered a multi-viscosity 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.

What makes 5W-40 CI-4 unique compared to other oil grades?

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.

Can I use 5W-40 CI-4 in all types of engines?

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.

Is 5W-40 CI-4 suitable for extreme weather conditions?

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.

Can I mix 5W-40 CI-4 with other oil grades?

Mixing the DEO 5W 40 Cl-4 diesel oil , while possible, I not recommended as it may damage your engine. Even when mixing, make sure to follow proper instructions

How often should I change 5W-40 CI-4 oil?

Oil change interval when using the DEO 5W 40 Cl-4 diesel engine oil  or any oil for that matter, depends upon your type of vehicle and how much you run it. There is no universal number for this.

Can I use 5W-40 CI-4 in older diesel engines?

Yes, you can use   DEO 5W 40 Cl-4 diesel engine oil in your older vehicle if your vehicle shows compatibility to the oil. Make sure to check your vehicle’s user manual for confirmation.
