Technical Conclusion:

The oil fails to meet several critical parameters required for compliance with various standards, indicating its unsuitability for the intended applications.

1. Phosphorus:

Measured Value: 0.0899%Standard Requirement: <0.08% for ACEA E6, MTU 3.1, and

MAN M3477Analysis: The elevated phosphorus content exceeds the limits set by ACEA E6, MTU 3.1, and MAN M3477 standards. Excessive phosphorus can lead to deposits and reduced efficiency of exhaust after-treatment systems, such as catalysts and diesel particulate filters.

2. Foamability:

Measured Values: 30/0, 80/0, 0/0 Standard Requirement: 10/0, 20/0, 10/0 for ACEA ,

Analysis: The oil exhibited excessive foam formation, particularly at 93.5°C (value of 80/0), significantly exceeding the acceptable range. Excessive foam can impair lubrication efficiency, leading to decreased engine performance and increased wear.

3. Pour Point:

Measured Value: -33°CFor 10W-40 Oil: This pour point is relatively high. Additionally, the oil cannot be classified as synthetic with such a high pour point. Synthetic oils typically have much lower pour points, allowing for better performance in cold temperatures. The relatively high pour point of this oil indicates that it does not possess the low-temperature properties expected of a synthetic oil, further limiting its suitability for applications where synthetic oil performance is required.Analysis: A pour point of -33°C is insufficiently low for a 10W-40 oil, potentially leading to difficulties in cold starts in harsh climatic conditions.

4. Total Base Number (TBN):

Measured Value: 8.48 mg KOH/g Standard Requirements’

E7: Not less than 9 mg KOH/g

MTU3.1: Not less than 12 mg KOH/g

MB 229.5: Not less than 10 mg KOH/g

Analysis:

The low TBN indicates insufficient acid-neutralizing capacity, which can lead to faster oil degradation and an increased risk of corrosion and deposits in the engine.

This makes the oil unsuitable for engines requiring compliance with ACEA E7, MTU 3.1, and MB 229.5 standards.

5. Ash Content:

Measured Value: 0.9%Standard Requirement: 1.0-1.5% for MB 229.1 / 229.5

Analysis:

The ash content is below the required range for MB 229.1 / 229.5 standards. Insufficient ash content may affect wear protection and engine durability.

Conclusion:

The oil does not comply with the requirements for phosphorus content, foamability, pour point, TBN, and ash content, making it unsuitable for classification under ACEA E6, E7, MTU 3.1, MAN M3477, and MB 229.1 / 229.5 standards. These nonconformities can lead to reduced lubrication efficiency, increased engine wear, and challenges with cold starts. It is strongly recommended to address these deficiencies to ensure the oil meets the necessary regulatory standards and provides reliable engine protection.
