Ethylene glycol vs water
WebViscosity. PG is more viscous than EG, this difference is especially noticeable at lower temperatures where viscosity increases. When operating at ~170°F the viscosity difference between EG and PG is about 10% and generally unnoticeable. At colder temperatures and start up conditions, PG will require significantly more energy.
