TL;DR: Prioritize LUBTEX TEXOIL GEAR 320 EP for heavy-duty Malaysian gearboxes experiencing high humidity and heat
High oxidation stability prevents chemical breakdown under thermal stress, which extends the operational lifespan of the fluid.
Demulsibility properties force rapid separation of water from the oil, preventing the formation of emulsions in high-humidity environments.
Extreme pressure additives create a high-strength physical barrier on metal surfaces to stop friction wear and gear tooth pitting.
Pass rating on corrosion metrics ensures active chemical protection against rust on internal components.
Low pour point characteristics maintain fluid mobility during cold startups or localized temperature drops.

| Kinematic Viscosity @ 40°C | 319.4 mm²/s |
| Viscosity Index (VI) | 102 |
| Flash Point (COC) | 248°C |
| Pour Point | -16°C |
| Corrosion Test | Pass |
| FZG Gear Test (Load Stage) | >12 |
Enclosed industrial gearboxes including spur, bevel, helical, and spiral reduction gear configurations.
Industrial circulating systems supplying continuous lubrication to heavy-duty plain and rolling-element bearings.
Industrial machinery processing lines requiring an extreme pressure fluid that maintains strong film strength under load.
Do not use in automotive hypoid differentials requiring API GL-5 specifications unless explicitly authorized by the machinery manufacturer.
Do not use in systems containing silver-plated components, as active extreme pressure additives can react with and corrode soft white metals.
The hydrotreated base oil configuration exhibits strong resistance to molecular shearing, maintaining the target oil film thickness under heavy mechanical loads.
An FZG load stage rating of greater than 12 demonstrates that the specialized additive package prevents scuffing and adhesive wear when gear teeth mesh under high torque.
The viscosity index of 102 ensures the fluid maintains sufficient kinematic viscosity to separate moving metal parts even as operating temperatures rise toward the 248°C flash point.
Active demulsifiers prevent moisture from bonding with the oil molecules, ensuring water drops directly to the bottom of the sump where it can be drained without degrading lubrication quality.
Suitable For: Maintenance engineers managing heavy manufacturing plants, palm oil mills, cement factories, or rubber processing facilities operating in tropical, high-humidity climates.
Suitable For: Procurement teams sourcing standard industrial gear oil replacements for European or Asian machinery specifying an ISO VG 320 extreme pressure lubricant.
Not Suitable For: Heavy sliding worm gearboxes where non-EP or specialized compounded gear lubricants are specified to protect yellow metals.
Not Suitable For: Food processing environments requiring NSF H1 food-grade registered lubricants due to potential incidental food contact risk.
Lock out and tag out the machinery according to plant safety regulations.
Drain the existing, degraded gear oil completely from the gearbox sump while the system is still warm to maximize fluid removal.
Flush the gearbox with a light flushing oil if heavy sludge or particulate contamination is present.
Clean or replace all internal oil filters and magnetic drain plugs to remove trapped metallic debris.
Fill the reservoir with new oil directly from the container using a clean pump or transfer container to avoid contamination.
Verify the fluid level via the physical sight glass or dipstick, ensuring it reaches the center line or designated full mark.
Restart the machinery and inspect all seals, gaskets, and external lines for leaks.
Mixing this mineral-based fluid with synthetic polyglycol (PAG) lubricants, which causes immediate fluid incompatibility, phase separation, and lubrication failure.
Overfilling the gearbox housing, leading to oil churning, increased operating temperatures, premature oil oxidation, and shaft seal leaks.
Operating the machinery beyond the designated oil drain interval, which depletes the extreme pressure additives and increases the risk of gear pitting.
Leaving oil storage drums uncovered outdoors, allowing rainwater to pool on the drum lid and breach the bung seals via thermal breathing.
Store the product in tightly sealed original containers within a well-ventilated, dry indoor facility away from direct sunlight and heat sources.
Utilize oil-resistant gloves and safety glasses during handling to prevent skin irritation and accidental eye contact.
Dispose of used industrial lubricants and contaminated packaging exclusively through licensed local environmental waste contractors in accordance with national regulations.
Avoid releasing used fluid into soil, water drainage systems, or local waterways.

What specific gearbox types are best suited for this oil?
This fluid is designed for enclosed industrial reduction gearboxes using spur, bevel, helical, or spiral configurations.
What does the FZG rating of >12 indicate?
It indicates high resistance to mechanical scuffing and tooth surface wear under heavy-duty extreme pressure conditions.
How does high humidity affect this lubricant?
The formula includes robust demulsifiers that rapidly separate water from the oil, allowing operators to drain moisture out of the sump easily.
Is this product compatible with synthetic gear oils?
No, it should not be mixed with synthetic base oils like PAGs due to chemical incompatibility risks. A complete system flush is required before switching fluid types.
