Manufactured by TSI Supercool, a reputable brand known for automotive fluids, this oil meets OEM performance specifications and is approved for use in a variety of makes and models. The product comes in a compact 8‑ounce container, weighing just 8 pounds, making it easy to store and handle during service. Its inclusion of a UV dye allows technicians to quickly locate leaks, saving time and reducing the need for extensive diagnostic procedures.

Key specifications include a product dimension of 9.5 x 7.5 x 6.5 inches, a weight of 8 pounds, and a model number P46-128D. The oil is compatible with all standard R134a systems and is designed to resist moisture absorption, a common cause of reduced cooling performance and component corrosion. With a customer rating of 4.8 out of 5 stars from 55 reviews, users consistently praise its reliability and effectiveness.

Beyond its core performance attributes, the oil also offers environmental benefits. The synthetic base reduces the need for frequent oil changes, thereby decreasing waste and the overall carbon footprint associated with vehicle maintenance. Its stable chemical composition ensures that it does not break down quickly, providing long‑term protection for the air‑conditioning system.

For service centers and independent garages, the oil’s packaging includes clear labeling and safety information, complying with industry standards. The product’s best‑seller rank of #22 in Air Conditioning Oils highlights its popularity among professionals seeking dependable lubrication solutions. Whether you are performing a routine service or addressing a specific compressor issue, this oil delivers the performance and peace of mind required for high‑quality automotive care.

In addition to the technical benefits, TSI Supercool provides comprehensive support resources, including technical data sheets, safety data sheets, and application guides. These resources help technicians understand the correct usage procedures, dosage recommendations, and best practices for achieving optimal system performance. The brand’s commitment to quality assurance is reflected in rigorous testing protocols that validate the oil’s durability, thermal stability, and compatibility with a wide range of compressor designs.

Usage

This oil is suitable for a broad spectrum of automotive air‑conditioning applications, from compact cars to larger SUVs. It excels in environments where the system is exposed to high humidity, temperature fluctuations, and frequent cycling. By providing excellent moisture resistance, the oil helps prevent the formation of acids that can corrode internal components, thereby extending the service interval and reducing maintenance costs.

When performing a compressor replacement or a complete system flush, the oil should be introduced after the system has been evacuated and dried. The recommended dosage is typically one ounce per pound of compressor weight, but technicians should consult the vehicle’s service manual for precise quantities. The UV dye included in the oil enables quick visual detection of leaks during pressure testing, allowing for immediate corrective action.

For DIY enthusiasts, the oil’s user‑friendly packaging and clear instructions make it accessible for home garage projects. The oil can be applied using a standard funnel or a dedicated oil injector, ensuring accurate delivery without spillage. It is also compatible with common refrigerant recovery equipment, making it a versatile choice for both professional and hobbyist applications.

In high‑performance or racing vehicles, where the air‑conditioning system may be subjected to extreme operating conditions, the oil’s high viscosity and anti‑wear additives provide an extra layer of protection. This helps maintain consistent cooling performance even under sustained high‑load scenarios, contributing to driver comfort and component longevity.

FAQ

What makes the 46V viscosity suitable for modern R134a systems?

The 46V viscosity strikes a balance between fluidity and protective film thickness. It flows easily at low temperatures, ensuring quick start‑up, while maintaining a robust lubricating layer at higher operating temperatures. This helps prevent metal‑to‑metal contact inside the compressor, reducing wear and extending the component’s service life.

Can I use this oil in a system that previously used mineral oil?

Switching from mineral oil to synthetic PAG oil requires a thorough system flush to remove any residual mineral oil, which can react with the new formulation. After flushing, the system should be dried and evacuated before introducing the PAG oil. Following these steps ensures compatibility and prevents potential performance issues.

How does the UV dye assist during leak detection?

The UV dye is mixed uniformly within the oil, allowing technicians to illuminate the system with a UV light source. Any leaks will fluoresce, making them visible even in hard‑to‑reach areas. This method speeds up the diagnostic process, reduces the need for extensive disassembly, and improves overall service efficiency.

Is this oil compatible with all makes and models that use R134a?

Yes, the oil meets OEM specifications for a wide range of manufacturers that employ R134a refrigerant. However, it is always advisable to consult the vehicle’s service manual or the manufacturer’s recommendations to confirm compatibility, especially for specialty or high‑performance applications.

What after‑sales support does TSI Supercool provide?

TSI Supercool offers a dedicated technical support line, detailed product documentation, and a warranty covering material defects. Customers can also access online resources such as installation videos, safety data sheets, and troubleshooting guides, ensuring they have the information needed for successful application and maintenance.
