Balmerol HP GL-4 80W-90 Extreme Pressure Multigrade Gear Oil – 1L

Balmerol HP GL-4 80W-90 Gear Oil 1L is a mineral-based extreme-pressure multigrade gear oil formulated for manual transmissions, drive axles and differentials where an API GL-4 80W-90 gear oil is specified. Official Balmer Lawrie product pages position this oil as a multi-purpose heavy-duty, long-drain-interval gear oil with selective EP additives for protection against wear and scoring, along with oxidation stability and service life support. This makes it a strong fit for buyers who need proper gearbox / transmission oil rather than a generic lubricant or engine oil substitute.

Your bottle photos confirm the key pack-side identifiers: Balmerol HP, GL-4, 80W-90, Extreme Pressure Multigrade Gear Oil, and 1 litre net content. The rear label also states that it is recommended for use in hypoid, spiral bevel or worm gear transmission systems of cars, buses and trucks, and the pack lists the commodity as lubricating oil. This is useful because many weak seller pages do not explain actual use cases properly and often leave buyers confused between gear oil, engine oil, hydraulic oil and differential oil.

This listing is intentionally written to prevent wrong orders. This oil is for applications that call for a GL-4 80W-90 gear oil. It is not a blind-buy replacement for every manual transmission fluid, every differential oil, or every GL-5 application. Some modern gearboxes, limited-slip differentials, CVTs, AMTs, DCTs, or manufacturer-specific transmission systems need very different fluids. So the correct way to buy this product is simple: check your owner’s manual or workshop recommendation first, verify the viscosity grade and performance level, and then match it to this bottle.

Why Buyers Choose This

Compatibility / Application

Best suited for:

• Manual mechanical transmissions where API GL-4 80W-90 is specified
• Drive axles and conventional differentials where GL-4 80W-90 is recommended
• Hypoid, spiral bevel or worm gear transmission systems as mentioned on the pack label
• Cars, buses, trucks and similar applications requiring this exact grade/spec

Check before ordering:

• Whether your application specifically requires GL-4 or GL-5
• Whether your gearbox needs manufacturer-specific manual transmission fluid instead of gear oil
• Whether the recommended viscosity is 80W-90 in your climate and service interval
• Whether your bike, scooter or automotive system actually uses separate gearbox oil

Not the right product for blind buying:

• Engine oil applications
• Brake fluid or hydraulic systems
• CVT, ATF, DCT or AMT transmission systems
• Limited-slip differential fluids unless separately approved
• Any application where the manufacturer clearly calls for GL-5 or OEM-specific fluid

Variants

• Single Bottle: 1 L

• Avoid skin contact with used oil and dispose of waste oil responsibly
• Do not assume this is suitable for modern automatic or specialty transmission systems

Frequently Asked Questions

Q1. What is Balmerol HP GL-4 80W-90 used for?
It is a gear oil for mechanical transmissions, drive axles and gear differentials where an API GL-4 SAE 80W-90 oil is specified.

Q2. Is this engine oil?
No. This is gear oil, not engine oil.

Q3. Can I use it in any gearbox?
No. Use it only where the manufacturer or workshop specification calls for GL-4 80W-90 gear oil.

Q4. What does GL-4 mean?
GL-4 is a gear-oil performance classification used for certain manual transmission and axle applications. It should not be treated as automatically interchangeable with every GL-5 or OEM-specific fluid requirement.

Q5. What vehicles can use this oil?
The official product page recommends it for heavy-duty gear differentials, mechanical transmissions and drive axles, while the bottle mentions cars, buses and trucks. Actual suitability still depends on the exact specification required by the machine or vehicle.

Q6. Can I use it in a limited-slip differential?
Not as a blind purchase. Limited-slip systems often need dedicated friction-modified fluids or specific approvals.

Q7. Can I use it in my motorcycle?
Only if your motorcycle or transmission specifically requires a separate GL-4 80W-90 gear oil. Do not assume universal motorcycle fitment.

Q8. Is this mineral or synthetic?
Retail specification listings identify it as mineral-based gear oil.

Q9. Is 1 litre enough for my vehicle?
That depends entirely on your gearbox, axle or differential oil capacity. Check your service manual before ordering.

Q10. What should I verify before ordering?
Verify the viscosity grade, performance level, application type and fill quantity required by your vehicle or machine.
