TSI Supercool PAG Compressor Oil 46 Viscosity with UV Dye, 32 oz — Synthetic PAG for R134a

TSI Supercool P46-32D is a 46-viscosity synthetic PAG compressor lubricant formulated for R134a automotive A/C systems and includes UV dye for leak detection.

This high-performance synthetic PAG oil is engineered to protect and lubricate automotive air conditioning compressors that use R134a refrigerant. It combines moisture resistance, anti-wear chemistry, and antioxidants to reduce friction, inhibit sludge formation, and help extend compressor service life. The built-in UV dye simplifies leak locating without affecting routine maintenance, and the formulation meets relevant OEM performance specifications for compatibility and reliability.

What makes this 46-viscosity PAG oil suitable for R134a systems?

The P46 formulation balances film strength and flow characteristics to match many R134a compressor requirements. Its synthetic PAG base resists moisture uptake better than conventional oils, which helps maintain lubrication quality over time.

• 46 centistoke viscosity at reference temperature for stable oil film
• Synthetic PAG base optimized for R134a refrigerant compatibility
• Moisture resistance to reduce oil degradation and corrosion risk
• Meets OEM performance standards for fit-and-forget serviceability

How does this oil protect the compressor and A/C components?

P46-32D includes anti-wear agents and friction modifiers that reduce metal-to-metal contact inside the compressor, lowering wear rates and improving efficiency. Antioxidants slow deposit and sludge formation so the system stays cleaner and operates closer to original performance.

• Anti-wear additives reduce bearing and vane wear
• Friction modifiers help lower operating load and energy use
• Antioxidants discourage sludge and varnish buildup
• Result: longer compressor life and steadier cooling output

How does the included UV dye help during service and diagnosis?

The integrated UV tracer dye allows technicians to quickly locate refrigerant leaks under UV illumination without separate dye-addition steps. Because it’s blended into the oil, the dye disperses with the lubricant and refrigerant for reliable detection during inspections.

• Pre-blended UV dye saves time during leak detection
• Visible under UV light to identify leak points precisely
• Compatible with standard A/C diagnostic UV lamps and filters
• Helps target repairs faster and reduce refrigerant loss

Is this oil compatible with my vehicle and how should it be used?

Use TSI Supercool P46-32D only in systems specified for PAG oil and R134a refrigerant with a 46-viscosity recommendation. Follow the vehicle manufacturer’s fill volumes and service procedures; always verify compatibility before mixing with other lubricant types.

• Designed for systems calling for PAG 46 with R134a
• Do not mix with mineral or ester oils unless specified by OEM
• Use correct service quantities and observe contamination controls
• Store and handle in a clean, dry environment to prevent moisture ingress

Who this is for: Professional technicians, independent A/C shops, and informed DIYers who work on R134a automotive air conditioning systems and need a reliable, OEM-grade PAG 46 lubricant with built-in UV tracing for efficient servicing and longer compressor life.
