Premium Performance Natural Gas Engine Oils

PETRONAS Geo NG Series are premium performance natural gas engine oils specially developed for the lubrication of a wide range of spark-ignited gas-fuelled engines in order to improve fuel- efficiency and reduce emissions.

Formulated with high quality selected mineral base oils enhanced with advanced anti-wear, anti- oxidant, detergent, dispersant, anti-rust and anti-foam additives, PETRONAS Geo NG oils provide excellent piston deposit, sludge and ash control, excellent TBN retention and thermal stability as well as resistance to oxidation/nitration.


PETRONAS Geo NG Series are recommended for use in:

  • medium to high speed four-cycle engines requiring a low ash oil
  • engines experiencing valve face and seat wear
  • lean-burn and stoichiometric four-cycle engines
  • engines equipped with catalytic converters
  • applications using alternate fuels containing low levels of sulfur or chlorine
