An A-C compressor oil formulated to protect and lubricate R134a systems, Denso ND-oil 8 Compressor Oil. Reliable operation and reduced maintenance worries help workshops and careful owners complete jobs with confidence. Does the specification and OEM approval make it the sensible choice for regular compressor care?
⚡ At a Glance
- • Viscosity Performance: PAG 46 grade maintains a consistent viscosity profile across operating temperatures
- • Best for: Technicians and vehicle owners servicing R134a A-C compressors
- • Not ideal for: Systems that use refrigerants other than R134a or require non-PAG lubricants
Formulated as PAG 46 oil for R134a compressors with a high viscosity index. Double end-capped chemistry reduces moisture uptake and meets DENSO Thermal Systems' OEM requirements.
Consistent Lubrication – Thanks to PAG 46 formulation
PAG 46 base oil provides the required viscosity profile for R134a compressors, maintaining flow and lubricating film across a wide temperature range. The higher viscosity index gives steadier shear characteristics under service conditions.
Stable lubrication reduces metal-to-metal contact and wear during operation, supporting longer compressor life and fewer unexpected failures.
Reduced Moisture Risk – With double end-capped chemistry
Double end-capped molecules limit hygroscopic behaviour, slowing moisture absorption compared with uncapped alternatives. Lower water uptake reduces potential for acid formation inside the system.
Reduced moisture uptake helps prevent corrosion and acid-related damage, which supports cleaner system internals and longer service intervals.
Manufacturer Compatibility – Thanks to DENSO OEM approval
Meets the specifications set by DENSO Thermal Systems for use in their compressors and is formulated specifically for R134a applications. OEM approval indicates suitability with DENSO-manufactured compressor materials and tolerances.
Compliance with DENSO requirements gives workshops confidence when selecting lubricants for installations and repairs that rely on manufacturer guidance.
