STARK 20W-50 CH-4-SJ

The STARK 20W 50 CH4-SJ is a Diesel engine oil used for lubricating a vehicle engine and reducing friction in moving parts. The 20W 50 is the viscosity rating of the STARK 20W 50 CH4-SJ Diesel engine oil . The rating in this case tells us that the oil is thick and is not able to flow and lubricate well at low temperatures. However, at high temperatures, it provides a thick film and lubricates very well. The CH-4 is a specification formulated by the American Petroleum Institute (API) meant for diesel engine oils . Oils rated as CH-4 exhibit better oxidation protection, wear protection, soot control and deposit prevention.  SJ is also an API classification and SJ oils exhibit better performance than oils of older specifications.

The STARK 20W 50 CH4-SJ diesel engine oil is typically applicable in fixed diesel engines, public work materials as well as mixed fleets of trucks and cars. This oil is oil is typically suitable for supercharged diesel engines or gasoline engines operating in cold climates. Therefore , even tho it has a vide application field, it does not necessarily apply to all vehicles.

 20W 50 oils, like the  STARK 20W 50 CH4-SJ Diesel engine oil are generally  hick and at high temperatures,  provide a thick film and lubricates very well. These oils are very resistant to high temperature and can be used in extremely hot climates.

There is no universal number as to how often you should change your  STARK 20W 50 CH4-SJ Diesel engine oil . It depends solely upon your vehicle type and the load you put on it. Consult your vehicle manual for guidance.

Using the STARK 20W 50 CH4-SJ diesel engine oil  indeed effects fuel efficiency positively. The oil reduces friction and minimizes energy losses, thus saving you fuel.
