Heavy-Duty Lubricant Selection Checklist

Correct lubricant selection protects engines, transmissions and hydraulic systems while reducing unplanned maintenance. Use this checklist before requesting a quotation.

1. Confirm the application

Identify whether the oil is for a diesel engine, heavy-duty gearbox, axle or hydraulic system. Different systems require different additive packages and performance standards.

2. Check the required standard

• CK-4, CI-4 or CH-4 for heavy-duty diesel engines
• GL-5 85W-90 for suitable heavy-load gear systems
• HM-46 for compatible hydraulic equipment

3. Match viscosity to the environment

Consider ambient temperature, load, operating hours and cold-start conditions. Always follow the equipment manufacturer manual when it specifies a grade.

4. Verify packaging and supply

Confirm package size, quantity, label language, pallet requirements and destination port. Ask for product specifications and available quality documents before shipment.

5. Send a complete inquiry

Provide equipment model, required grade, viscosity, quantity and destination. This allows a faster and more accurate recommendation.
