The Unsung Hero of Automotive Cooling: Inside PAG-Based A/C Compressor Oils – And the Launch of OSCAR PAG 46 & PAG 100
By Oscar Lubricants
As temperatures rise across the globe and vehicle technologies continue to evolve, one component remains critical to driver comfort and system efficiency: the automotive air conditioning compressor. While most discussions focus on refrigerants like R134a or R1234yf, very few talk about the lifeblood of the system—the compressor oil.
Today, Oscar Lubricants proudly announced the launch of OSCAR PAG 46 and OSCAR PAG 100, two premium-grade polyalkylene glycol (PAG)-based compressor oils engineered for compatibility with R134a, R1234yf, and R1234yf systems in hybrid and electric vehicles.
This launch not only marks a new milestone in our portfolio—it reflects our commitment to next-generation vehicle technology and extreme climate performance.
Why PAG-Based Compressor Oils Are Critical
Air conditioning compressor oils must perform in tight spaces, under high pressure, and at rapidly shifting temperatures. PAG oils are the industry standard for modern A/C systems due to their:
- Excellent lubricity under high load
- Thermal and oxidative stability
- Compatibility with synthetic refrigerants like R134a and R1234yf
- Good miscibility with refrigerants for effective circulation
However, not all PAG oils are created equal. Viscosity, additive balance, and purity levels make all the difference in compressor longevity and system efficiency.
Introducing OSCAR PAG 46 & PAG 100
After months of lab development and real-world testing in the Middle East’s extreme climate, we now introduce:
OSCAR PAG 46 – Low-viscosity, fully synthetic compressor oil ideal for new-generation R1234yf systems and electric vehicles, where lower drag and higher
efficiency are required.
OSCAR PAG 100 – Higher viscosity formula designed for larger displacement compressors and systems operating under more demanding thermal conditions,
including high-output A/C units in SUVs and commercial vehicles.
Both formulations are:
-
Fully synthetic PAG oils
-
Compatible with R134a, R1234yf, and hybrid systems
-
Non-conductive (suitable for EV systems)
-
Contain advanced additives for anti-wear, corrosion resistance, and seal conditioning
Application Versatility
OSCAR PAG oils are tested across a wide range of vehicle platforms:
-
Passenger Cars – Smooth cooling and quiet compressor operation
-
Hybrid & Electric Vehicles – Non-conductive and low moisture content
-
Commercial Fleets – Extended service life and better system protection
-
Aftermarket Servicing – Fully OEM-compatible for workshops and AC specialists
Each product is packaged for OEMs, professional workshops, and distributors, with bulk availability from our blending plant in the UAE.
Built for the GCC Climate
Vehicles in the Gulf region endure intense A/C use—often for 8 to 10 months of the year. This puts massive thermal and mechanical stress on the A/C system. That’s why we’ve designed OSCAR PAG oils to perform in:
- High ambient temperatures exceeding 50°C
- Dusty environments prone to contamination
- Long service intervals typical of the region
Our in-house R&D lab has validated both grades using ASTM D97 (Pour Point), ASTM D445 (Kinematic Viscosity), and lubricity tests to ensure durability and protection in harsh conditions.
Ready for the Future of Mobility
As OEMs shift to low-GWP refrigerants like R1234yf and design systems for electrified powertrains, the compressor oil must keep pace. Oscar Lubricants is proud to support this evolution with cutting-edge solutions like OSCAR PAG 46 and PAG 100.
