1. Sealing
Use the original bottle cap or a replacement seal (such as a food-grade plastic cap) and ensure it is fully tightened. If the original tinfoil film is damaged, cover the bottle opening with multiple layers of clean plastic film, fold it in half, and then tighten it. If possible, use wax to seal.
For industrial-grade oil tanks, check that the breather valve is unobstructed to prevent secondary contamination caused by negative pressure.
2. Storage Environment
Select a cool, dry, and dark indoor environment. The recommended temperature is 5-30°C. Keep away from fire, high temperatures, and chemicals.
Avoid direct sunlight or humid areas (such as basements) to prevent oxidation or emulsification of the engine oil.
3. Storage
Store engine oil tanks upright to maintain pressure balance and reduce the risk of leakage.
Industrial oil tanks should be stored securely. When stored outdoors, store them horizontally and covered with a rainproof sheet. 4. Classification and Labeling
Store different types of engine oil (mineral, semi-synthetic, and fully synthetic) separately and label them with the date and type of opening. Follow a first-come, first-served basis.
Unopened engine oil has a shelf life of 3-5 years. Once opened, mineral oil should be used within 6 months, while fully synthetic oil can be stored for 12 months.
5. Safety and Protection
Metal oil tanks should be treated to prevent rust, and plastic drums should be protected from contact with strong acids and alkalis.
Check the seals regularly and address any leaks or odors immediately.
6. Usage Precautions
When adding engine oil, leave a small amount of residue at the bottom to prevent moisture or impurities from entering the engine.
Check the oil condition (color, odor, and fluidity) before use after long-term storage.
