Savant Labs offer testing according to (Society of Automotive Engineers) SAE J300 to determine an engine oil’s SAE viscosity grade. Four viscosity tests determine the multi-grade parameters. A multi-grade oil’s viscosity grade is often expressed as #W##, for example 5W30 or 0W20. The “W” in the viscosity grade stands for “winter”.
Low-Temperature tests the determine the first number in a multi-grade oil:
- ASTM D5293 Cold Cranking Simulator
- ASTM D4684 TP-1 MRV Viscosity
High-Temperature tests that determine the second number in a multi-grade engine oil:
- ASTM D445 Viscosity, Kinematic at 100°C
- ASTM D4683 High-Temperature High Shear / TBS Viscosity at 150°C
Savant Labs can run tests to confirm or help you determine the SAE J300 viscosity grade. The Savant Labs' technical team has a deep understanding of this testing slate and we can help you. For more information contact us or request a quote for your next testing project.
