Because cold-temperature storage can be detrimental to the performance of some AMSOIL products, AMSOIL provides the following cold storage recommendations:
Freeze-Tolerant Lubricants
Store all AMSOIL lubrication products at temperatures at least 10°F above the lubricant’s pour point (-20°F to be safe). Some lubricants are designed for use in extreme cold temperatures, which also effectively lowers their cold storage limit. However, ideal storage temperature is 32°F (0°C) to 85°F (29°C). Long-term storage in temperatures out of this range can cause additive separation over time, reducing overall lubrication effectiveness and lifespan.
Gear Oil: SEVERE GEAR® SAE 250 above 0°F
Freeze-Tolerant Fluids
These AMSOIL products either do not freeze or suffer no adverse effects from a freeze-thaw cycle:
Fuel Additives
Diesel Injector Clean + Cetane Boost
Other Fluids
Slip Lock®: If product separates, warm to room temperature and shake well before use.
Heavy-Duty Degreaser: warm to room temperature before use.
Brake Fluid: Do not store below -40°F longer than two weeks.
