High Performance Anti-wear Circulating Oil

PETRONAS Circula Series are high anti-wear circulating oils specially developed for a wide range of heavy duty circulating systems.

Formulated with high quality selected mineral base oils enhanced with advanced anti-wear, anti- oxidant, anti-rust and anti-foam additives, PETRONAS Circula oils provide very good anti-wear, rust and corrosion protection, smooth operation of the circulating system and up to 2x longer lasting performance*.

*vs. minimum requirements of ISO 11158 HM fluids based on TOST (ASTM D943)


PETRONAS Circula Series are recommended for use in:

  • various heavy duty circulating systems requiring high anti-wear properties
  • circulating systems including plain or rolling-element bearings and hydraulics
  • spur and helical gear drives where no EP performance is required


Very good anti-wear protection

Protects equipment components from excessive wear and provides long equipment life

High oxidation stability

Maintains performance levels under regular temperatures and pressure

Very good rust & corrosion protection

Inhibits the corrosion process that occurs in presence of water, improving equipment life

Very good water separability

Due to water separability the system is protected from water degenerative effects, maintaining circulating system efficiency at required level and reducing maintenance costs
