Solving the Increasing Oil Shortage: Engine Oil Analysis Results After Approximately 54,341km of Driving Released

Kawawe Co., Ltd. (Headquarters: 3-3-9 Minami-Horie, Nishi-ku, Osaka; Representative Director: Takamitsu Iibe) announced that verification conducted by Chiba Green Energy Co., Ltd., the manufacturer of the engine oil additive "BANSHOU," confirmed no significant abnormal trends in engine oil after approximately 54,341km of driving in a vehicle using "BANSHOU," based on an investigation by a third-party analysis institution. In this verification, engine oil was collected from a vehicle that had undergone actual long-distance driving, and items such as wear metals, soot content, fuel dilution, kinematic viscosity, and total base number (TBN) were analyzed. The condition of the engine oil was quantitatively confirmed. The results confirmed that "performance was maintained even at mileage levels typically considered for replacement."

"Approaching 'Oil Supply Anxiety': A Solution to Engine Oil Supply Concerns"

Amid recent changes in international affairs, uncertainty surrounding the Strait of Hormuz, a crucial chokepoint for global crude oil transportation, is increasing. Japan relies heavily on the Middle East region for much of its crude oil imports, raising concerns about potential impacts on the supply and price trends of petroleum-related products. Engine oil, being one such petroleum-derived product, may also be affected by fluctuations in raw material prices and logistics costs. Against this backdrop, attention is focused on "how to effectively utilize finite resources for as long as possible" and "how to suppress engine oil consumption." In light of these societal circumstances, continuous verification is being conducted on the potential of the engine oil additive "BANSHOU" to maintain oil performance. This time, the analysis by a third-party institution of engine oil used in a vehicle that had driven approximately 54,341km confirmed that engine oil degradation was suppressed, and its performance was maintained.

Third-Party Analysis of Engine Oil After Approximately 54,341km of Driving

Engine oil was collected from a Lexus NX300 vehicle after approximately 54,341km of driving and subjected to analysis by a third-party analysis institution.

The analysis confirmed the following items:

・Wear metals (Iron, Copper, Aluminum, etc.)
・Soot content (Combustion products)
・Fuel dilution rate
・Kinematic viscosity (Lubrication performance indicator)
・Total Base Number (TBN: Cleaning performance indicator)

Analysis Results:
Item | Analysis Result
---|---
Iron (Fe) | 11ppm
Copper (Cu) | 1ppm
Aluminum (Al) | 5ppm
Soot content | 0.02%
Fuel dilution | 1.3%
Kinematic viscosity (40℃) | 72.41mm2/s
Total Base Number (TBN) | 2.09

The analysis results confirmed that kinematic viscosity was maintained within the specified range, and wear metal levels remained low. Furthermore, the soot content was 0.02% and the fuel dilution rate was 1.3%, indicating that oil performance was maintained even after long-term use.

Regarding Verification of Long-Term Engine Oil Use

With increasing interest in crude oil prices and the risk of petroleum product supply due to changes in global conditions, a new approach to engine oil usage is required. Our company is focusing on the possibility of appropriately extending engine oil replacement intervals based on actual analysis data, and we will continue verification by third-party analysis institutions. Furthermore, by releasing analysis data obtained under actual usage environments, we aim to provide useful information to users and strive to propose new options for more efficient utilization of limited resources.
