TSI Supercool POE 68 Automotive A/C Compressor Oil Quart — 1234yf EV/Hybrid with UV Dye

TSI Supercool 48663-32D is a quart of POE 68 lubricant formulated with UV dye for leak detection and safe use in 1234yf electric and hybrid vehicle A/C compressors.

This synthetic polyol ester (POE) oil is engineered for modern automotive air conditioning systems that use 1234yf refrigerant, including electric vehicles and hybrids that require non-traditional compressor lubricants. The bottle contains a complete additive package and built-in ultraviolet dye to help technicians locate leaks quickly during diagnostics and service. With a 68 cSt viscosity rating, it balances flow and film strength to support lubrication and system compatibility across a range of temperatures encountered in vehicle A/C circuits.

How does this oil work with 1234yf in EV and hybrid A/C systems?

TSI Supercool POE 68 is compatible with 1234yf refrigerant and formulated to mix and circulate with refrigerant in automotive A/C loops. Its POE base is chosen for chemical compatibility with modern compressor materials and seals commonly found in electric vehicle systems. The included additive package helps maintain system cleanliness and performance during operation.

• Formulated specifically for 1234yf refrigerant systems
• POE base designed for electric/hybrid compressor compatibility
• Additives aimed at protecting internal components and reducing deposits
• 68 cSt viscosity to balance lubrication and refrigerant circulation

What does the UV dye do and how is it used for leak detection?

The bottle contains UV-reactive dye that disperses through the A/C system with the oil and refrigerant, making leaks visible under a UV lamp. Technicians run the system to circulate the dye, then inspect hoses, fittings, and components with a UV light to identify dye traces. This speeds up locating leaks compared with pressure or soap tests alone.

• Pre-mixed dye saves a step during service and diagnosis
• Visible under standard automotive UV inspection lamps
• Helps pinpoint leaks at seals, hoses, and fittings quickly
• Compatible with common A/C diagnostic workflows

Is this product safe for the compressors and seals used in electric vehicles?

TSI Supercool POE 68 is formulated to be safe for the elastomers, bearings, and electrical components typically found in EV and hybrid compressors when used as directed. POE oils are commonly specified for modern systems because they are compatible with the chemistry of current lubricants and materials. Always follow vehicle manufacturer guidelines for oil type and charge amounts to ensure system integrity.

• Designed with materials compatibility in mind for EV/hybrid compressors
• Appropriate viscosity for lubrication and oil return in A/C circuits
• Contains protective additives to minimize wear and deposits
• Not a substitute for following OEM oil quantity and service procedures

Who is this for: Technicians and DIYers servicing modern automotive A/C systems using 1234yf refrigerant—especially electric and hybrid vehicle owners and repair shops—will find this TSI Supercool POE 68 quart helpful for maintenance, repairs, and leak detection. It is intended for use where POE oil with UV dye is recommended; always verify compatibility with the specific vehicle make and model before adding lubricant.
