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

Bar and Chain Oil
