Gear STR

Premium Quality Industrial R&O Gear Oils

PETRONAS Gear STR is a premium quality R&O industrial gear oil specially formulated for the lubrication of plain and anti-friction bearings, gears and crank mechanisms in which lubricants with extreme pressure (EP) and detergent properties are not required.

It is manufactured from specially selected premium quality base oils for their oxidation stability and water separating characteristics, and further fortified with selected oxidation and corrosion inhibitors to ensure long lasting protection. It is available in ISO 32 through ISO 460 viscosity grades.

Customer Benefits

Superior thermal and oxidation stability to resist oil degradation and thickening for longer oil service life.

Rapid water separation and anti-foam properties to ensure trouble-free operation.

Specially selected additive system prevents the formation of damaging deposits, varnish and rust.

Its additive system will not corrode bronze or silver components.


Recommended for the lubrication of enclosed gears, mobile or stationary hydraulic systems and non-turbine circulating oils where an EP type of lubricant is not required.

Highly recommended for industrial equipment requiring R&O type oil such as electric motor bearings, blowers, pumps, compressors and machine tools. It is particularly recommended for lubrication on bronze on steel worm gears.

The lighter grade is for used in bearings and gears working under high speeds and low loads while the more viscous grades are for bearings, cranks and gears working under low speeds and high loads as well as for high pressure compressors.

Pressol Syn RS

Synthetic Food Grade Compressor Lubricants

PRESSOL SYN RS Series are high quality non-toxic synthetic compressor lubricants. These series are based on synthetic hydrocarbons (PAO), formulated with FDA approved ingredients only and approved by the USDA for applications where incidental food contact may occur.

PRESSOL SYN RS series meet USDA H1 approval with NSF International for use in food and beverages processing plant applications.

Customer Benefits


Less compressor maintenance

Excellent oxidation resistance

Excellent anti-wear properties

Fewer oil changes

Lower oil consumption

Reduced varnish lacquering and deposits

Greatly reduced fire and explosion hazard

Compatible with compressor seals, gaskets, hoses and air system components.


PRESSOL SYN RS series are recommended for all types of compressors where incidental food contact may occur with oil in the discharge air.

May also be considered for other applications requiring an oxidation resistant lubricant.

PRESSOL SYN RS series are available in viscosity range from ISO VG 32 to 150, make it an ideal lubricant for many applications in the food processing industries. For example: chains, hydraulic, pumps, gear-motor and bearings.

Nominal operating Range is -37°C to 180°C


18 Liters pail, and 209 Liters drum


PRESSOL SYN RS series are compatible to mineral oil and is similar to mineral oils in their compatibility with paints, seals, gaskets and hoses. No special precautions related to compatibility required when changing over from a mineral oil lubricant to a PRESSOL SYN RS synthetic hydrocarbon based lubricant.


PRESSOL SYN RS synthetic lubricants are field tested, approved or recommended by most major compressor manufacturers. Should you have any questions regarding the suitability of PRESSOL SYN compressor lubricants for a specific manufacturer's model compressor, please contact PETRONAS DAGANGAN BERHAD.

Danol XHT

High Quality Inhibited Heat Transfer Oil

PETRONAS Danol XHT is A high quality heat transfer oil formulated for use in most direct and indirect fired heat transfer systems with forced circulation where the fluid is subjected to the most severe operating conditions. It is made from premium quality high viscosity index paraffinic base oils for their excellent heat transfer properties (specific heat and thermal conductivity) at all temperatures to provide more rapid heating and greater system flexibility. A thermally stable oxidation inhibitor additive is added to enhance its outstanding thermal and oxidation stability which can easily resist thermal cracking and chemical oxidation and maintain in solution any decomposition product that forms to maintain heat transfer system efficiency.

Customer Benefits

Outstanding resistance to thermal cracking and oxidation thus preventing excessive sludge and coke deposits formation for longer oil service life.

High thermal conductivity - heats quickly for fuel economy and even heat distribution.

Low vapour pressure - minimized fluid loss due to evaporation, vapour lock and hazards of flammability.

Low temperature start-up for prompt circulation.

Non-corrosive to aluminium, brass, bronze, copper and steel.


For use in both open and closed heat transfer systems with forced circulation. For closed systems, maximum heater outlet temperature is 305 °C and maximum heater wall temperature is 320 °C.for any open system, the operating temperature shall not exceed 200 °C for safety purposes

Operating Advice

When starting up a new unit or restarting a unit after maintenance work or operating a unit irregularly, the temperature of the unit should be reduced to around 100 °C to allow steam blow off before returning to the normal operating temperature.
