Technical Conclusion:
The COMMA Ecoren 5W-30 oil fails to meet critical performance specifications, particularly for cold-weather performance:
- Low-Temperature Performance:
- Pour Point: The oil has a pour point of -33°C, which may not allow it to flow properly at -35°C during cold starts. This suggests that it could fail the MRV (Mini-Rotary Viscometer) test at -35°C, impairing its ability to provide adequate lubrication in cold temperatures, potentially causing poor cold-start performance.
- Consequences for Buyers:
- Cold Start Issues: The oil may cause increased engine wear, reduced efficiency, and possible engine damage if used in colder climates due to its poor cold-weather performance.
- Warranty Concerns: Using this oil in vehicles requiring compliance with the specified standards could lead to warranty issues, especially if engine damage occurs due to the oil’s insufficient cold-start performance.
