LLC “Nefteprodukt” offers a wide selection of hydraulic oils under the “Optimal” trademark with delivery throughout Ukraine. We have been producing lubricants since 2001 and guarantee high quality, confirmed by certificates and testing. You can order oil in bulk or retail, packaged from 1 to 200 liters, with delivery via Nova Poshta or transport companies.

Hydraulic oil is a key element of any hydraulic system, playing a critical role in the transmission of mechanical energy. Properly selected oil ensures trouble-free operation of equipment, reduces component wear, and saves on repairs. For stable and long-term operation of a hydraulic system, it is important to follow the manufacturer’s recommendations and replace the oil regularly. This not only extends the service life of equipment but also reduces operating costs.

Types and Properties of Hydraulic Oil

Modern hydraulic oils are developed with key characteristics in mind, such as low-temperature stability and viscosity. Viscosity is an important indicator for proper system operation, as it affects movement speed and lubrication efficiency in equipment components.

Viscosity grades ISO VG and their applications:

  • ISO VG 32 — used at temperatures down to -20°C. Suitable for construction equipment and forklifts.

  • ISO VG 46 — used at temperatures down to -15°C. Applied in machine tools, hydraulic presses, and other industrial equipment.

  • ISO VG 68 — used at temperatures down to -10°C. Recommended for hydraulic systems operating in warm indoor environments.

  • ISO VG 100 — used at temperatures down to -5°C. Applied in heavy-duty hydraulic systems, industrial equipment, and heavy presses.

Low-viscosity oil can lead to increased operational losses, poorer lubrication, and even cause fatigue wear of working components. On the other hand, high-viscosity oil may create difficulties in low-temperature operation, increase mechanical losses, and cause additional resistance.

Modern hydraulic systems use oils that comply with ISO VG standards, which indicate the oil viscosity level at 40°C. This allows precise oil selection depending on operating conditions and equipment requirements.

Modern Standards and Environmental Requirements

With the development of technology, hydraulic oil manufacturers follow international standards such as DIN 51524, ISO 6743, and SAE J300. In addition, environmental requirements are becoming stricter: biodegradable oils are increasingly in demand, especially in industries where environmental safety is a priority.

We offer both traditional mineral oils and modern biodegradable oils that are safe for the environment.

Advantages of “Optimal” Hydraulic Oils

LLC “Nefteprodukt,” actively developing since 2001, has become one of the largest manufacturers of automotive and hydraulic oils in Ukraine. The “Optimal” brand oil is highly chemically and oxidatively stable, enabling it to perform effectively in a wide range of temperatures without forming deposits or sludge.

Features of “Optimal” oils:

  • high filterability;

  • resistance to water exposure;

  • minimal foaming;

  • anti-corrosion properties;

  • availability of quality certificates and compliance with international standards;

  • positive feedback from customers in various industrial and agricultural sectors.

When to Change Hydraulic Oil

There are several signs indicating the need to replace hydraulic oil:

  • foaming;

  • increased acidity;

  • sulfur odor;

  • increased specific gravity;

  • reduced transparency.

We recommend changing oil every 1,500–2,000 operating hours or according to the manufacturer’s recommendations.

It is also important to remember that mixing oils from different manufacturers or with different additive types can negatively affect system performance. If you need to replace oil, be sure to thoroughly clean the hydraulic tank and other system components.

Recommendations for Oil Replacement

When replacing oil, it is recommended to use pumps for filling to prevent air and debris from entering the system. This increases equipment efficiency and reduces the likelihood of malfunctions.
