Fubex LASER 15W-30 CG-4/SJ Diesel Engine Oil

Laser 15W 30 is a high-quality mineral oil of a Universal nature. It is a gasoline engine oil as well as a diesel engine oil. It is particularly suited for naturally aspirated or super-charged engines powered by diesel as well as gasoline engines.






Laser 15W 30 engine oil lubricates the moving parts of engine thus, preventing wear and corrosion. Since Laser 15W 30 can be used as a hydraulic oil, it possesses features like demulsibility.


Laser 15W 30 diesel engine oil is recommended for mixed fleets of trucks and cars operating in cold climatic conditions. It is also suitable for fixed diesel engines and hydraulic systems. 

Laser 15W 30 engine oil is designed to lubricate engines requiring API CG-4/SJ performance lubricants

15W-30 CG-4/SJ engine oil is a mineral engine oil.  It works equally well in gasoline and diesel engines. CG-4/SJ is the API service classification. CG-4 indicates that it is suitable for high-performance, four-stroke diesel engines. SJ means that this gasoline engine oil is suitable for gasoline engines designed before 2001.

15W-30 CG-4/SJ oil is primarily well suited for diesel engines, automobiles such as cars and trucks and is also a good choice for hydraulic systems such as backhoes and implements.

It is the lubricant’s viscosity grade according to the SAE. The first part, 15W indicates the viscosity of engine oil in winter. The number 30 represents the oil viscosity at 100C.

Yes indeed, Laser 15W 30 mineral engine oil is suitable for both gasoline and diesel engines.

There is no universal number as to how often you should change your Laser 15W 30 mineral engine oil. It depends solely upon your vehicle type and the load you put on it. Consult your vehicle manual for guidance.

Using the Laser 15W 30 Diesel engine oil indeed effects fuel efficiency positively. The oil reduces friction and minimizes energy losses, thus saving you fuel.

The Laser 15W 30 Diesel engine oil provides great lubrication and reduces friction. The oil is characterized by its superior engine cleanliness, wear Protection, acid neutralizing ability and low Ash content
