TSI Supercool PAG 100 Synthetic A/C Compressor Oil 32 oz with Built-In UV Dye — R134a Compatible, High-Viscosity Protection

TSI Supercool P100-32D is a 32 oz high-viscosity PAG 100 synthetic lubricant with built-in UV dye formulated for R134a automotive A/C systems.

This lubricant combines a moisture-resistant synthetic PAG base with additives designed to minimize wear, control oxidation, and keep A/C systems cleaner longer. It’s engineered to meet OEM performance expectations for modern R134a compressors and contains a UV tracer to simplify leak detection without needing separate dye products.

How does this PAG 100 oil protect my R134a A/C compressor?

The formulation uses targeted anti-wear agents and friction modifiers to lower metal-to-metal contact in compressor components. By reducing wear rates and smoothing operation, it helps components run more efficiently and can slow the development of mechanical wear that leads to premature failure.

• Anti-wear chemistry that reduces compressor surface damage
• Friction modifiers to improve moving-part efficiency
• Synthetic PAG base designed for high-temperature stability
• Compatible with typical R134a compressor materials when specified

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

The integrated UV dye makes hidden refrigerant leaks visible under a UV lamp, eliminating the need to add a separate tracer. Technicians can inspect for dye traces around hose connections, seals, and service ports to quickly pinpoint leak sources during diagnostics.

• Built-in tracer simplifies leak detection workflow
• Works with standard UV lamps and inspection lights
• Visible dye deposits appear at leak points for targeted repairs
• Eliminates extra dye-handling steps during service

Why choose a 100 viscosity synthetic PAG instead of a lower viscosity oil?

A 100 viscosity grade provides a thicker film at operating temperatures, which is beneficial for certain compressors and systems designed for that oil weight. Thicker oil films can offer improved boundary protection under heavy load or higher-temperature conditions where thinner oils might break down or fail to maintain adequate lubrication.

• Higher film strength for better protection under stress
• Improved resistance to moisture ingress compared with some alternatives
• Designed to meet OEM viscosity requirements for select R134a systems
• Helps maintain consistent lubrication in robust compressor designs

How does this product help keep the A/C system cleaner and more reliable?

Anti-oxidants in the formula slow oxidation reactions that lead to sludge, varnish, and deposits inside the system. Cleaner internals preserve heat-exchange efficiency and minimize blockages in expansion devices, helping the A/C system deliver steady performance over time.

• Anti-oxidants limit sludge and deposit formation
• Cleaner internals reduce risk of orifice blockages and valve sticking
• Maintains thermal transfer efficiency in evaporator and condenser coils
• Supports longer service intervals when installed correctly

Who is this for: TSI Supercool P100-32D is intended for automotive technicians, fleet maintenance teams, and informed DIYers who work on R134a air conditioning systems that specify a PAG 100 oil. It suits systems where OEM guidance calls for a 100 viscosity PAG lubricant and when integrated UV tracing is desired for efficient leak diagnostics. Always verify compatibility with vehicle manufacturer requirements and follow proper service procedures when adding or replacing compressor oil.
