Important Information

Choosing the Correct Engine Oil

Use the viscosity grade and service category recommended by the engine or equipment manufacturer.

01

Check SAE Viscosity

Confirm that SAE 15W-40 is an approved viscosity grade for your engine and expected operating conditions.

02

Check API Category

Choose CI-4+, CH-4 or CF-4 only where the engine manufacturer specifies that category or confirms an applicable replacement.

03

Confirm Technical Data

Refer to the current technical data sheet and certificate of analysis for actual viscosity, flash point, pour point and other test results.

Technical information: For numerical laboratory values such as kinematic viscosity, viscosity index, flash point, pour point, TBN and density, please refer to the latest approved product TDS / batch COA. Confirm the required SAE grade and API service category with the engine manufacturer before use.
