Oil for gas engines

When the number of gas powered vehicles increased significantly, a market emerged for products related to this automotive sector.

More and more modern models of gas installations are being imported, and candles and oils for gas engines have also come into fashion.

The operating conditions of spark ignition engines fed from a properly selected and technically sound installation differ only slightly from the operating conditions of an engine running on gasoline. LPG has a higher octane rating than gasoline and creates fewer harmful compounds when burned. It is important to note that HBO does not wash oil off cylinder surfaces and does not dilute it in the oil pan. The oil film applied to the rubbing parts is preserved long protective elements against friction. It should be emphasized that in an engine running on gas, the used oil tested organoleptically is less contaminated than the oil when the engine is running on gasoline.

Special "gas" oils are produced on a mineral basis and can be used in engines running on liquefied petroleum gas or methane. These products have been developed to protect the engine from the high temperatures that occur during the combustion of the gas fraction. The advertising slogans that accompany this product group emphasize the same benefits as with conventional oils. "Gas" oils protect the engine from wear. They have detergent properties, due to which they limit the formation of carbon deposits, sludge and other deposits in the engine. They prevent contamination of the piston rings. Finally, they protect the engine from corrosion and rust. Manufacturers of these oils recommend changing them after a run of 10-15 kilometers. Most oils have a viscosity grade of 40W-4. Domestic "gas" oils do not have a quality classification label, while foreign products have a quality specification label, such as CCMC G 20153, API SG, API SJ, UNI 9.55535, Fiat XNUMX.

Experts say that the lubricants recommended by the plant for this type of engine are sufficient to lubricate the power unit. However, specially designed "gas" oils can somewhat slow down the adverse processes resulting from the various operation of the gas fuel supply system, as well as neutralize the influence of contaminants contained in poorly purified gas.

In principle, there is no good reason to justify the use of a special oil marked "Gas" for the lubrication of LPG engines at the end of their service life on the engine oil used so far. Some experts in the field argue that special oils for lubricating internal combustion engines running on liquefied gas are a marketing ploy, and not the result of technical needs.
