Gas engine oils used in biogas or natural gas engines have special formulations that differ from diesel and gasoline engine oil formulations. This is because natural gas engines have:

• A clean burning process with no soot contamination. Therefore, the oils require less detergency/dispersancy (lower ash levels).
• A gaseous fuel source with no risk of fuel dilution. The prevention of a viscosity increase in the oil is more critical.
• A hotter burning process, which is typically from 165 to 235 degrees C. Thus, oxidation/nitration is of greater concern. (The heat may be caused by hot spots within the oil’s circulation located near the piston rings and the combustion chambers.)    

For gas engines, the goal is to obtain a lubricant with higher thermal and oxidative stability or to create a lubricant with a minimal oxidative degradation. Standard results for lubricants with poor oxidation protection/control are:

• Sludge formation/filter blockage
• Oil thickening /increased viscosity
• Formation of deposits/oxidation products such as lacquers, varnishes, etc.
• Increased acidity

These operating problems can be prevented by the combination of a good quality base oil with a supplemental antioxidant package. A typical gas engine oil formulation may contain multiple antioxidant additives to help protect the base stock from excessive heat or catalytic degradation. 

Antioxidants added alone or in synergistic combinations extend the operating life of the oil by improving its oxidation stability. During their use in lubrication systems, oxidation inhibitors will deplete to a certain critical level, at which point the fluid will start to degrade/polymerize at an accelerated rate. When this happens, important changes in the physical properties of the base stock occur. The oil or lubricant is no longer able to protect the equipment, and its useful life is over.

There is a growing interest in methods predicting an oil change by measuring antioxidant concentration during the lubricant’s lifetime. Monitoring the onset and the propagation of oxidation will lower operating costs and allow users to detect abnormally oxidized and degraded lubricants.

The basic mechanism of oxidative degradation and the role that different antioxidants play begin with the formation of reactive compounds, better known as free radicals, hydro peroxides and peroxides. These reactive compounds propagate into oxygenated hydrocarbons, such as alcohol, acids and sludge. The antioxidants act in two ways: by removing radicals (primary antioxidancy) or by decomposing hydro peroxides to form non-reactive products, which do not participate in further oxidation of the lubricant. Currently, the most commonly used primary antioxidants are the phenolic, phenates, salicylates and amine types; the secondary antioxidants are usually sulfur or metal-containing additives.

Once the antioxidant additives are depleted, the base oil is more vulnerable to oxidation. This may explain why the oil’s viscosity tends to increase as more operating hours accumulate on the gas engine.

Figure 1 shows a RULER voltammogram for different gas engine oil formulations. As you can see, the selection of different types of antioxidants is applied for the gas engine oil formulations, where the following types of antioxidants are used:  Zincdithiophosphates (ZnDTP), aromatic amines, phenates, phenols and salicylates.

MANUFACTURING PROCESS OF ENGINE OIL is not very complicated. For the production, there is need usable and tried a formulation, ingredients ( performance and another additives, base oils,foam agent, pour point depressant, etc. ) and process tank. For ingredients to be used, quantities to be used and ingredients usage rankings, you should look into this formulation and manufacturing process. Therefore, formulation and productıon process of MULTIGRADE, MONOGRADE,SYNTHETIC,SEMI SYNTHETIC MOTOR OIL are important. If you have not a good formulation, you cannot make healthy and  efficient production of any lubricating oils.
