PAG 150 R134a A/C Compressor Oil – 8 oz, ISO VG 150, Heavy-Duty Systems

The HCPRO Performance PAG 150 is a high-viscosity PAG compressor oil for heavy-duty R-134a A/C — trucks, fleet vehicles and light HVAC equipment running R-134a.

Key features

• ISO VG 150 PAG — film strength for high-pressure, heavy-duty systems
• Heavy-duty fit — trucks, fleet vehicles and certain commercial applications
• Thermal stability — 455°F flash point, -31°F pour point, wear protection
• Tested to ASTM and ANSI-ASHRAE 97-1989 — lubricant performance standards
• 8 oz / 237 mL — single, 6-pack or 12-pack

Who this oil is for

Heavy-duty truck A/C technicians. Fleet maintenance teams servicing commercial vehicles. Auto A/C techs working on full-size SUVs and pickups where OEMs spec heavier viscosity. Service techs on certain commercial refrigeration and light HVAC units running R-134a with PAG 150.

When to use it

During R-134a A/C compressor service when the OEM calls for ISO VG 150. Full compressor refill: 4–8 oz per OEM spec (heavy-duty systems often run higher capacities — check the manual). Top-off after recharge: 1–2 oz per circuit. The right choice for high-pressure or high-load applications.

Why PAG 150 vs PAG 100, PAG 46, or POE

PAG 150 is the heavy-duty choice for high-pressure R-134a compressors. PAG 100 is standard for domestic vehicles; PAG 46 for lighter-duty imports. POE is for modern HFC and A2L refrigerant systems — not compatible with R-134a PAG systems. Running PAG 100 in a PAG 150 system causes premature wear under load.
