COMPRO™ Compressor Fluids


COMPRO™ Compressor Fluid is a premium quality lubricant specifically designed to provide long and highly reliable service life in industrial air compressor applications.

COMPRO’s unique chemistry starts with a blend of 99.9% pure base oils, produced using the HT Purity Process. These crystal clear fluids are free of impurities that can hinder lubricant performance. Utilizing more than 30 years of formulating experience, Petro-Canada fortifies these thermally stable fluids with specially selected additives to provide strong protection against oxidative breakdown, wear and corrosion.


With stronger resistance to sludge and varnish formation versus leading mineral oils, COMPRO provides worry-free operation and can reduce overall compressor maintenance costs

Features & Benefits

  • Resists oxidative breakdown better than leading mineral oil based fluids

    • Strong resistance to oxidative breakdown caused by exposure to air at high discharge temperatures.​

    • Keeps compressor components free of sludge and varnish to ensure trouble free operation and lower maintenance costs on fluid change-out.

    • Provides oil change intervals of up to 2,000 hours service in rotary screw compressors, and 500 hours service in reciprocating compressor.

    • Reduces oil thickening, which can improve compressor efficiency and lower energy consumption costs.

  • High thermal stability reduces carbon deposit formation

    • Improves compressor efficiency​

    • Extends maintenance intervals for valves and intercoolers

  • Excellent protection against wear

    • Prolongs the service life of working components​

    • Can extend the time between compressor overhauls

    • Reduces overall maintenance costs

  • Protects against rust and corrosion 

    • Helps to extend component life, especially when running intermittent service in high humidity conditions​

  • Low volatility reduces oil carry-over into the air system

    • Reduces fluid consumption cost​

Operational Considerations

The full benefits of a change to COMPRO Compressor Fluid will only be realized by minimizing contamination with the previously used oil. Certain makes of compressors do not permit complete draining, so if the drained oil is heavily oxidized (shown by significant increase in the oil’s total acid number and viscosity), recharging with COMPRO may not result in optimum performance and fluid service life.


While COMPRO, COMPRO XL-S and COMPRO XL-R Compressor Fluids are fully compatible with most mineral and synthetic compressor fluids, they should not be mixed or contaminated with fluids containing polyalkylene glycols or silicones. COMPRO Synthetic Compressor Fluid is compatible with polyalkylene glycols but should not be mixed with mineral oils or silicones.

Compressor Fluid Grade Selection & Service Life

Note: The above are general guidelines only.

COMPRO Compressor Fluids are designed for air compressors running under moderate conditions. For severe service or special compressor applications, we recommend the following:


COMPRO XL-S Compressor Fluid

  • Specially formulated to extended fluid life in rotary screw compressors

  • Provides up to 8,000 hours (4X longer) service life in rotary screw compressors operating at air discharge temperatures of up to 85 degrees C)

  • Available in ISO 32, 46, 68, 100 and 150 viscosity grades



COMPRO™ Synthetic Compressor Fluid

  • Specially formulated to extended fluid life in rotary screw compressors operating under extreme conditions, or where the risk of compressor downtime cannot be compromised

  • Provides up to 8,000 hours (4X longer) service life in rotary screw compressors operating at air discharge temperatures of up to 105 degrees C

  • Available in an ISO 32/46 v
