■ About the “Use All at Once” Recommendation
The recommendation in our catalog to use the entire contents at once is to prevent potential performance degradation caused by mixing with other additives or improper storage after opening.
In particular, exposure to moisture or foreign matter after opening can alter the formulation and reduce the product's effectiveness. Therefore, we provide this guidance as a precaution.
However, if the unused portion is kept clean, tightly sealed, and properly stored, it can be safely used at a later time.
■ Storage Method and Shelf Life
Storage： Store in a cool, dark place away from direct sunlight, preferably inside the original packaging. Avoid high temperature and humidity.
Sealing: After opening, tightly close the cap and ensure no contaminants or moisture enter the container.
Shelf life： Even after opening, the product can be used within approximately two years if properly stored.
■ Important Usage Notes
Do not use this product in combination with other engine oil additives. Doing so may cause chemical reactions or sedimentation.
When adding the product, measure accurately and use at 5–10% of the total engine oil volume.
