TSI Supercool 1234yf PAG-46H Compressor Oil 8 oz — Synthetic, Moisture-Resistant Lubricant

TSI Supercool 27262 is an 8 oz synthetic PAG-46H compressor lubricant formulated specifically for automotive A/C systems that use HFO-1234yf refrigerant.

This PAG 46H oil delivers targeted lubrication for compressors operating with 1234yf, offering moisture resistance, anti-wear protection, and conditioners to help keep A/C components moving smoothly. Packaged in a convenient 8-ounce size, it’s designed for topping off or servicing compressors during repairs and retrofits. The formula is compatible with systems that may contain R134a components and emphasizes long-term protection rather than short-term performance spikes.

What does this lubricant do for my 1234yf A/C compressor?

It provides the necessary film strength and friction control inside the compressor, helping bearings, shafts, and valve assemblies operate with reduced wear. The added conditioners and inhibitors help maintain internal cleanliness and protect metal surfaces under load.

• Delivers 46 cSt viscosity suited for many automotive compressor designs
• Reduces metal-to-metal wear with anti-wear agents
• Supports stable lubrication across typical vehicle operating temperatures

How does this oil handle moisture and contaminants?

TSI Supercool PAG 46H is formulated to resist moisture uptake better than some baseline PAG oils, helping reduce the risk of corrosion and acid formation. The package includes inhibitors and conditioners that help neutralize or limit the effects of minor contamination that can enter during service.

• Advanced moisture resistance minimizes hydroscopic issues
• Inhibitors protect internal components from corrosive byproducts
• Conditioners help maintain consistent oil performance over time

Is this product compatible with other refrigerants and systems?

Primarily designed for HFO-1234yf systems, this synthetic PAG lubricant is also safe for use in R134a systems when specified by the service procedure. It’s not intended to be mixed indiscriminately with ester-based or POE oils without following manufacturer guidance or a full system flush.

• Formulated for HFO-1234yf automotive systems
• Can be used in R134a systems when allowed by service instructions
• Avoid mixing with incompatible oil chemistries unless system has been properly cleaned

How much oil do I need and when should I use this 8 oz bottle?

The 8 oz bottle is convenient for topping off compressors after minor service, small repairs, or when replacing a clutch or seal. For a full compressor rebuild or replacement, verify the manufacturer’s specified oil charge — larger quantities may be required.

• Ideal for topping off or adding to an existing oil charge
• Use during clutch, seal, or small component repairs
• Check compressor manufacturer specs for full-charge amounts

Who is this product for: Technicians, DIY mechanics, and automotive service centers working on vehicles equipped with HFO-1234yf A/C systems who need a reliable, high-performance synthetic PAG oil in a handy 8 oz package. It’s suited to those who require moisture-resistant lubrication with anti-wear additives and who follow proper service procedures when mixing or replacing oils.
