Technical Conclusion:
For 5W-30 oil, a pour point of -33°C is considered high, as the MRV (Mini-Rotary Viscometer) standard is measured at -35°C. This suggests that the oil does not meet the requirements for the 5W-30 classification and is more accurately classified as 10W-30.
Implications of High Pour Point:
- Insufficient Low-Temperature Performance: The elevated pour point indicates inadequate low-temperature performance, which can result in poor cold start protection and reduced flow at low temperatures. This deficiency can lead to increased engine wear and potential damage during cold starts.
Conclusion:
Given these factors, this oil does not conform to the 5W-30 standard and should be reclassified accordingly. It is essential for users to be aware of this classification to ensure optimal engine performance and protection, particularly in cold conditions.
