DENSO ND-OIL 8 is a PAG 46 (Polyalkylene Glycol) compressor oil designed for conventional belt-driven A/C compressors in passenger vehicles. DENSO Corporation manufactures it in Japan for piston, rotary, scroll, and sliding vane mechanical compressors operating with R134a refrigerant.
DENSO ND-OIL 8 is a synthetic PAG 46 lubricant formulated specifically for mechanical A/C compressors found in conventional passenger vehicles. The PAG 46 viscosity grade provides optimal lubrication for piston-type, rotary, scroll, and sliding vane compressors that are driven by the engine's serpentine belt. It delivers excellent thermal stability, a high viscosity index, and chemical inertness, ensuring the compressor operates efficiently while minimizing wear.
This oil is compatible with R134a refrigerant and is manufactured to meet DENSO's stringent quality standards. OEM part numbers include DND08250 (250 ml), 446963-0030, and the Toyota cross-reference 08885-09109. DENSO ND-OIL 8 is widely specified across Toyota, Lexus, Honda, and other automotive platforms with conventional belt-driven A/C systems.
DENSO ND-OIL 8 is used in service and replacement scenarios for passenger vehicle air conditioning systems equipped with mechanical belt-driven compressors. It is the designated lubricant for piston, rotary, scroll, and sliding vane compressor types when the system uses R134a refrigerant.
When a mechanical A/C compressor is replaced on a passenger vehicle using R134a, ND-OIL 8 provides the correct PAG 46 charge. The 250 ml can is the standard workshop service fill.
After a system flush following contamination or compressor failure, fresh PAG 46 replaces oil lost during recovery. Using ND-OIL 8 restores the OEM-specified lubrication grade.
Where a service sheet lists Toyota 08885-09109 or DENSO 446963-0030, ND-OIL 8 (DND08250) is the correct 250 ml PAG 46 compressor oil for the job.
Independent service centers performing multiple A/C jobs on conventional R134a systems can rely on ND-OIL 8 as a trusted PAG 46 grade for mechanical compressor types across various OEM platforms.
Before you order: confirm the compressor is belt-driven and the refrigerant is R134a. Electric compressors (EV/hybrid) require POE oil, not PAG. Through Vane and TVS compressors may require PAG 100 (ND-OIL 9) instead of PAG 46. See the ND-OIL selection table below.
PAG 46 is the industry-standard viscosity grade for piston, rotary, and scroll compressors in conventional automotive A/C systems. The "46" designation refers to the oil's kinematic viscosity, which is optimized for the operating speeds and load conditions of belt-driven compressors. Using a viscosity grade outside the OEM specification can lead to insufficient lubrication or excessive drag, reducing compressor lifespan and system efficiency.
DENSO ND-OIL 8 is chemically compatible with R134a and with the elastomer seals, hoses, and O-rings used in conventional A/C systems. It resists moisture absorption better than mineral oils and provides superior protection against wear compared to earlier refrigerant oil types.

This oil is manufactured and supplied by Guangzhou Qishanr Technologies Co., Ltd., trading as the brand QISHANR. The company is based in Foshan, Guangdong, adjacent to Guangzhou Port, and has been producing lubricants for more than 10 years from its own blending plant. That plant runs at an annual capacity of 6,000 tonnes, which is what allows us to hold stock on the grades we list and quote firm lead times rather than promising on behalf of a third party.
Refrigeration oils are the core of the business, but they are not the whole plant. The same lines produce general industrial lubricants, so a mixed enquiry that covers both refrigeration oils and ordinary industrial grades can be quoted, packed and shipped together instead of being split across suppliers.
This is not the full range. Specialised ester base oils and lubricant additives are produced in-house as well, which is the reason the synthetic ester grades can be specified to a target rather than bought off a shelf. If the grade you need is not listed above, send the specification or the product you are replacing and we will confirm whether we produce it.
Long-term partners get pricing that reflects a stable manufacturing base rather than a trading margin, and the same technical contact stays with the account from grade selection through to repeat orders.
The grade designations, part numbers and compatibility information on this page follow the manufacturer documents listed below.

Request ND-OIL 8 QuoteDENSO ND-OIL 8 is a PAG 46 (Polyalkylene Glycol) synthetic compressor oil made in Japan by DENSO Corporation. It is specified for conventional belt-driven A/C compressors in passenger vehicles, with compatibility for R134a refrigerant and mechanical compressor types including piston, rotary, scroll, and sliding vane.
No. ND-OIL 8 is compatible with R134a only. For R1234yf systems with mechanical belt-driven compressors, use ND-OIL 12 (PAG 46). For R1234yf systems with electric compressors, use ND-OIL 14 (POE).
The Toyota OEM equivalent is part number 08885-09109. The DENSO part numbers are DND08250 (250 ml) and 446963-0030. All three refer to the same PAG 46 compressor oil specification for mechanical R134a compressors.
ND-OIL 8 (PAG 46) is for piston, rotary, scroll, and sliding vane compressors. ND-OIL 9 (PAG 100) is for Through Vane, Through Vane Scroll (TVS), and scroll compressors specifically called out for the higher viscosity grade. Check the compressor nameplate or service manual for the specified viscosity.
No. ND-OIL 8 is a PAG oil for belt-driven compressors. Electric compressors (found in EV and hybrid vehicles) require POE oil due to electrical insulation requirements. Use ND-OIL 11 (POE, R134a/R1234yf) or ND-OIL 14 (POE, R1234yf) for electric compressors.
For the PAG 100 grade used in conventional R134a through vane and scroll compressors, see DENSO ND-OIL 9 PAG 100 compressor oil. For POE oil used in electric compressors on EV and hybrid vehicles, see DENSO ND-OIL 11 POE compressor oil.
