Technical Conclusion:
The Comma Prolife 5W-30 504/507 oil exhibits several critical issues concerning its performance and compliance with industry standards:
Key Issues:
- Low-Temperature Performance:
- Pour Point: -33°C
- Analysis: The pour point of -33°C suggests that the oil is likely to fail the MRV (Mini-Rotary Viscometer) test at -35°C, a requirement for 5W-30 oils. If the oil cannot pass this test, it may not provide adequate flow during cold starts, particularly in very cold climates. This inadequacy increases the risk of poor engine lubrication, potentially leading to engine damage under extreme low-temperature conditions.
Conclusion:
The Comma Prolife 5W-30 504/507 oil, with its insufficient low-temperature performance indicated by a pour point of -33°C, poses significant risks for adequate engine lubrication in cold conditions. It is recommended to select oils with better low-temperature properties to ensure reliable engine protection and performance in harsh environments.
