AMSOIL synthetic lubricants are designed to retain their original performance after a reasonable period of time in your garage or storeroom. Proper storage ensures the freshest, most effective products possible and longest AMSOIL shelf life.
What’s the shelf life of AMSOIL motor oil?
Product shelf life varies depending on product design, environmental contamination, chemical contamination and temperature.
Most liquid AMSOIL lubricants can last five years if you follow the suggestions below and properly store your products.
What’s the shelf life of AMSOIL synthetic grease?
Because grease can harden or lose its oil content over time, it generally has a storage life of two years.

AMSOIL engineers products that retain their original performance for as long as possible. Here are a few suggestions to maximize the time products may safely be stored.
How to maximize motor oil shelf life
Always store products in their original containers and, when possible, in a clean, dry, moderately temperate area. Store lubricants away from solvents and cleaning agents.
Store lubricants indoors to avoid damage from environmental contamination and temperature fluctuations. Follow these best practices if outdoor storage is your only option:
- Protect containers from the elements (direct sunlight, dirt, water, snow, rain, etc.)
- Keep containers off the ground by storing them on pallets
- Store unopened drum-packaged lubricant containers horizontally (except grease)
To reduce the possibility of extended storage, use the first-in/first-out (FIFO) method to ensure the oldest inventory is used first.
Factors that affect oil shelf life
Contamination – Water intrusion and the migration of water vapor, along with the introduction of foreign materials like cleaning agents and solvents, can cause a lubricant to degrade, resulting in reduced performance.
Temperature – The ideal storage temperature is 32°F (0°C) to 85°F (29°C). Temperatures out of this range can promote water migration, cause additive separation and reduce the effectiveness of additives over time.
AMSOIL aerosol storage
As a rule of thumb, don’t expose aerosol cans to direct sunlight or heat as they may burst if they become too hot. Store them away from heat sources, flames, sparks, hot surfaces or battery terminals. Don’t puncture or incinerate cans. Store in a cool, dry, well-ventilated area.
While there are no adverse issues with cold-temperature storage for most of our aerosols, we recommend allowing them to warm to room temperature before use. Miracle Wash, however, should be stored above 32ºF (0ºC).
