Idemitsu PAG 46 Compressor Oil for R134a — 8 oz can, thermal‑stable PAG lubricant

This compact 8 ounce can of Idemitsu PAG 46 delivers the specialized viscosity and chemical stability modern automotive air conditioning systems demand. Engineered with Idemitsu's double‑end‑capped PAG technology, this oil resists thermal breakdown and hydrolysis while providing the correct lubrication characteristics for compressors designed for PAG 46 and refrigerant R‑134a. The small size is ideal for top‑ups, service work, or keeping in a technician’s kit for spot repairs.

How does Idemitsu PAG 46 protect my A/C compressor?

Idemitsu PAG 46 is formulated to reduce wear and maintain proper lubrication under the high temperatures and pressures inside automotive A/C compressors. Its chemical and thermal stability helps prevent varnish and deposit formation that can impair moving parts.

• High lubricity that minimizes metal‑to‑metal contact in compressor components.
• Chemically stable formula reduces oxidation and deposit buildup.
• Hydrolysis resistance protects performance when trace moisture is present.
• Specifically matched viscosity for compressors requiring PAG 46.

Is this oil compatible with my R‑134a system and seals?

Yes — this PAG 46 oil is intended for automotive A/C systems that use R‑134a and specify PAG 46 lubricant. It is formulated to be compatible with common elastomers and components found in modern vehicles, though full system compatibility depends on manufacturer requirements.

• Compatible with compressors and components designed for PAG 46 oil.
• Designed to work with standard A/C hose seals and O‑rings used with R‑134a.
• Not for use in systems requiring mineral oil or POE without manufacturer approval.
• Refer to vehicle service manual for exact oil specification and capacity.

How much oil should I use and when is an 8 oz can appropriate?

Compressor oil volume varies by vehicle and service task. The 8 oz container is best for adding small measured amounts, topping off after repairs, or servicing vehicles with small oil capacities; it is not intended to replace a full system charge when large volumes are required.

• Use for small top‑ups or when adding precise ounces during compressor replacement.
• Ideal for technicians needing portable, single‑service containers.
• Consult vehicle specifications for total compressor and system oil capacity.
• Measure and return captured oil where applicable during component swaps.

What manufacturing standards and performance features does Idemitsu PAG 46 meet?

Idemitsu PAG 46 is produced to rigorous industry standards to ensure consistent quality and performance. The formula includes the brand’s patented double‑end‑capped PAG chemistry for improved long‑term stability under automotive operating conditions.

• Manufactured to ISO and IATF quality standards for consistent production.
• Double‑end‑capped PAG technology for superior thermal and chemical stability.
• Optimized for automotive A/C efficiency and compressor longevity.
• Provides reliable wear protection under elevated temperature and pressure.

Who this product is for: The Idemitsu PAG 46 8 oz compressor oil is designed for professional technicians, independent mechanics, and knowledgeable DIYers who service automotive A/C systems that specify PAG 46 lubricant for R‑134a refrigerant. It’s a practical choice when you need a precisely measured, high‑stability oil for compressor installation, small top‑ups, or on‑the‑go repair kits. Always confirm your vehicle manufacturer’s lubricant specification before use to ensure compatibility and correct fill volumes.
