Every hydraulic system — from a CNC press in Chakan MIDC to an injection moulding machine in Bhosari — depends on one thing going right: the hydraulic oil grade. Specify ISO VG 32 in a system designed for ISO VG 46, and you face seal incompatibility, erratic cylinder movement, and accelerated pump wear. Specify ISO VG 68 where 46 is required, and energy losses climb while response times slow. Getting the grade right matters — and so does getting it from a supplier who understands why.
Imperiea Engineering & Sourcing Pvt. Ltd. is an ISO 9001:2015 certified ISO VG 46 Hydraulic Oil Supplier in Pune, supplying genuine ISO VG 46 Hydraulic Oil in Pune from GS Caltex (Kixx) and Savsol to manufacturers across Pune, PCMC, Chakan, Talegaon, Ranjangaon, and Bhosari MIDC. Whether your plant runs 10 hydraulic presses or 200 CNC machining centres, we supply the right grade, in the right quantity, on time.
What is ISO VG 46 Hydraulic Oil?
ISO VG 46 is a viscosity grade designation defined by ISO 3448 — International Standard for Industrial Liquid Lubricants. ‘VG 46’ means the oil has a kinematic viscosity of 46 centistokes (cSt) at 40°C, with a tolerance range of 41.4–50.6 cSt. This mid-range viscosity makes ISO VG 46 the most widely specified hydraulic oil grade globally — suitable for the majority of industrial hydraulic systems operating in normal ambient temperature conditions (15°C to 40°C).
In Pune’s manufacturing environment — where plant temperatures typically range from 20°C to 38°C across seasons — ISO VG 46 delivers the ideal balance of film strength at operating temperature and cold-start flow at morning startup. It is the default specification for most Japanese and Korean machine tool OEMs (Mazak, DMG Mori, Doosan, Hyundai WIA) and European press manufacturers (Bosch Rexroth, Eaton Vickers).
Where is ISO VG 46 Hydraulic Oil Used?
| Equipment Type | Industry / Sector | Why ISO VG 46 |
| CNC Machining Centres & Turning Centres | Auto Components, Precision Engineering | OEM-specified for most CNC hydraulic systems |
| Hydraulic Presses & Power Presses | Sheet Metal, Stamping, Forging | Maintains pressure stability across operating cycle |
| Injection Moulding Machines | Plastics & Rubber, Auto Parts | Controls clamping force and injection speed precisely |
| Excavators & Construction Equipment | Infrastructure, Mining | All-season viscosity for field-use hydraulic circuits |
| Industrial Hydraulic Power Units | General Engineering, Process Plants | Standard grade for centralised HPU systems |
| CNC Grinding & Milling Machines | Tooling, Die & Mould | Precise slide movement control, low heat generation |
ISO VG 46 vs ISO VG 68 — Which Does Your Machine Need?
The two most common hydraulic oil grades in Pune’s manufacturing plants are VG 46 and VG 68. Here is how to decide:
| Parameter | ISO VG 46 | ISO VG 68 |
| Viscosity at 40°C | 46 cSt (41.4–50.6 range) | 68 cSt (61.2–74.8 range) |
| Ambient Temperature | 15°C – 40°C (standard Pune conditions) | 25°C – 50°C (high ambient or tropical) |
| Best For | CNC machines, presses, injection moulding | Heavy presses, outdoor equipment, high-load systems |
| OEM Guidance | Japanese & Korean CNC OEM default | Many European press OEMs recommend 68 |
| Cold Start Performance | Better — flows faster at morning startup | Slightly slower cold-start flow |
| Film Strength at High Load | Adequate for normal industrial systems | Stronger — better for shock loads |
Rule of thumb: if your machine OEM manual says ‘ISO VG 46’ or ‘HLP 46’ — use VG 46. If unsure, share your machine model and our technical team will confirm the correct grade before you order.

Frequently Asked Questions — ISO VG 46 Hydraulic Oil Pune
Q: How often should I change ISO VG 46 hydraulic oil in my CNC machine?
A: For most CNC machines running single-shift operations in Pune conditions, ISO VG 46 hydraulic oil should be changed every 2,000–4,000 machine hours or annually — whichever comes first. For machines running two or three shifts, or operating near coolant contamination sources, a 12-month change interval is safer. Always check your machine OEM manual for the manufacturer’s recommendation.
Q: Can I mix ISO VG 46 from different brands in my hydraulic tank?
A: Mixing lubricants from different brands is strongly discouraged, even if both are ISO VG 46. Different additive packages can react adversely, causing foam, sludge, or filter blockage. If switching brands, drain and flush the hydraulic tank completely before filling with the new product. Our team can advise on the correct flushing procedure.
Q: Do you supply ISO VG 46 hydraulic oil in small quantities for trial?
A: Yes. We supply Kixx Hydro and Savsol HY Fluid ISO VG 46 in 20-litre pack sizes for initial trials. After confirming suitability for your system, we can supply in 55-litre and 210-litre drums for regular use.
Q: Is ISO VG 46 hydraulic oil suitable for excavators and construction equipment?
A: Yes, ISO VG 46 is the standard hydraulic oil for most excavators, wheel loaders, and hydraulic construction equipment operating in India’s climate. For equipment operating in extreme heat (above 40°C ambient) or very cold conditions, a VI-improved grade like Kixx Hydro HDZ 46 or a synthetic grade may be preferable.
