Supreme Performance Synthetic (PAG) Industrial Gear Oil

PETRONAS Gear Syn WI Series are supreme performance industrial gear oils specially developed for worm gear drives across wide temperature range.

Formulated with high viscosity index polyalkylene glycol synthetic base oil (PAG) enhanced with advanced anti-wear, anti-oxidant, anti-rust and anti-foam additives, PETRONAS Gear Syn WI oils provide excellent anti-wear protection, outstanding load carrying properties, smooth operation of the gear drives systems and extremely long lasting performance allowing in some cases even “filled for life” type of applications.

PETRONAS Gear Syn WI Series meets or exceeds key industrial specifications and OEM requirements.


PETRONAS Gear Syn WI Series are recommended for use in:

  • enclosed worm gear drives demanding extremely long life lubrication, in some cases even “filled for life” approach is possible
  • calenders and compressors operating in conditions exceeding capabilities of conventional mineral oils
  • high temperature bearing and circulation systems with bulk oil temperatures up to 200°C

Note: Ordinary industrial paints soften in the presence of PAG based products. Internal gear drives surfaces should ideally be unpainted, or coated with resistant materials, for example a resistant epoxy coatings. PETRONAS Gear Syn WI oils must never be mixed with mineral oil or PAO based products. They are free of chlorine, sulphur and metal based additives.
