For systems smaller than shown, use half the quantity of antifreeze/coolant required for a system twice as large. Ethylene Glycol-Based Engine Antifreeze/Coolant Protection Chart
dictate which of the glycols is chosen for a particular application - toxicity and viscosity. Toxicity. EG is more toxic than PG. About 2 - 4 ounces of EG can be fatal if ingested by an adult human. Conversely, PG is a food additive which is not harmful to humans if ingested in moderate amounts. Comparison of Ethylene Glycol vs. Propylene Glycol
