Safety and Toxicity Information:
SIERRA Antifreeze is formulated with
propylene glycol rather than conventional ethylene glycol the base used for
traditional antifreeze. While attaining performance characteristics comparable to ethylene
glycol based antifreeze, SIERRA Antifreeze provides additional benefits. SIERRA
Antifreeze's propylene glycol formula is less toxic and therefore safer than ethylene
glycol coolants. This provides safety to children, pets, and animals in the environment
exposed to antifreeze leakage. Moreover, SIERRA Antifreeze's less toxic
base remains safer even after use in your engine.
