Petromin Petrogas 2 (Low Ash)

DESCRIPTION
Petromin Petrogas 2 (low ash) Oil Series is gas engine oils blended using solvent treated base oils and low ash chemical additives. Petromin Petrogas 2 (low ash) is primarily designed for two and four cycle, spark ignition, industrial gas engines, where minimization of lubricant ash induced port plugging is main consideration.

APPLICATIONS

Suitable for crankcase lubrication of natural gas fueled engines of high compression ratio and turbo charged models where oils meeting API CF and United States Engine Manufacturer’s Association (US EMA) Lowash category are required. Also suitable for Two-cycle stationary engines on sweet natural gas or LPG, also use in older-fourcycle stationary engines on sweet natural gas or LPG.


BENEFITS

• The low-phosphorus detergent additive provided excellent piston deposit control & balanced sulphated ash level reduces valve surface deposits.

• Outstanding oxidation minimizes acid number increases, provided protection against bearing corrosion.

• Very high oxidation stability protects against the formation of gums and varnishes, reduces oil thickening and increases oil life.

• Low phosphorus content also ensures exhaust system catalyst compatibility, and therefore maximizes unit’s service life.

• Protects copper lead bearing corrosion.
