An unopened, factory-sealed bottle of motor oil generally has a shelf life of
up to 5 years under proper storage conditions.
Storage Conditions Matter Most
- Ideal Temperature: Keep between 0°C and 29°C (32°F to 85°F).
- Avoid Extreme Heat: High heat accelerates oxidation and additive breakdown.
- Avoid Freezing & Thawing Cycles: Extreme cold causes additive packages (like detergent dispersion agents) to separate from the base oil.
- Keep Dry: High moisture or humidity can lead to condensation inside the plastic container over time.
