What you need to know about gas engine oil

If the gas generator you use requires a lubricant, it’s always best to select a specialist gas engine oil. Manufacturers like Mobil produce such lubricant products that are designed especially for
generator gas engines. A specific set of additives in gas engine oil products offer the highest level of protection from deposit build-up, wear and oxidation.

Gas engine oils can also ably cope with elevated temperatures, as they offer enhanced properties of thermal stability. Such lubricants can be used where the level of oil consumption is low; typical examples include high-speed, four-cycle engines or gas compressors. Other formulations are best suited to lean-burn or stoichiometric engines as well as cogeneration or ebullient cooled procedures. Gas engine lubricants also protect equipment, prolonging its life and lowering downtime, and display reliable chemical stability.

What’s different about gas engine oil?

The formation and accumulation of ash and carbon deposits are kept at bay by detergency and dispersion systems contained within the gas engine oil’s formula. The build-up of such deposits can reduce engine performance in the longer term. Specialist formulas also boast a superior level of resistance to corrosion, which helps to prevent scoring, scuffing and other types of damage to components, especially such parts as cylinders, valves, rings, bearings and pistons. This can result in a longer engine life, as well as a reduction in the requirement for maintenance and repair, which saves users money.

What are some of the best gas engine oils?

Mobil’s Pegasus range is a great example of a lubricant that has been designed to perform within high-demand, high-output gas engines, such as a turbocharged stoichiometric gas engine or lean-burn engine. A carefully chosen set of additives ensure superb performance levels, and it can also be used in conjunction with ebullient cooled or cogeneration applications.

Mobil Pegasus 1, for instance, features a unique formulation that helps to minimise of ash deposits, and build-up that can occur around ring belts and piston lands. This gas engine oil can also reduce wear on the valve face and seat, and minimise liner scuffing. It also offers low volatility, a high viscosity index and impressive oxidation resistance, which leads to improved engine performance at extreme temperatures and lower oil consumption. A low traction coefficient, meanwhile, assists during operations at high speed or high loading.

Pegasus 710 from Mobil is another premium gas engine oil, designed chiefly for lubricating high-speed four-cycle engines. Typically such engines feature a lean-burn design, which makes it challenging to get sufficient lubricant to the valve guide areas. This particular formula is also ideal for the lubrication of gas compressors. Its additives protect engine and compressor parts, while impressive chemical stability and oxidation resistance help to guard against wear and deposit build-up. It also boasts exceptional detergency and dispersancy, and it is robust enough to be used with engines that contain low amounts of corrosives.

Mobil Pegasus 805’s formula is also resistant to oxidation, and its thermal stability can extend equipment life. This lubricant has exceptional load carrying capability, which reduces wear on piston rings and liners.

Using the ideal gas engine oil has huge benefits for performance, productivity and engine longevity, so it’s wise to select just the right formula for the gas generator concerned.
