Technical Conclusion:
The Comma Prolife 5W-30 504/507 oil exhibits several significant issues regarding 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. Such a temperature is more typical for 10W-30 oils. If the oil cannot pass this test, it may not provide adequate flow during cold starts, particularly in very cold climates. This situation 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 inadequate low-temperature performance indicated by a pour point of -33°C, raises significant concerns about its ability to ensure reliable engine lubrication in cold conditions. It is advisable to select oils with better low-temperature properties to protect engine performance and integrity in harsh environments.
