Is Prestone Antifreeze Highly Corrosive?

[Karla]

Prestone Antifreeze is non-corrosive as long as it is genuine. Below is relevant information: 1. Composition: Prestone Long-Life Universal Antifreeze/Coolant contains no phosphates, borates, or silicates. It utilizes special chemical components and formulation technology to extend the lifespan of corrosion inhibitors, making it particularly suitable for areas with water containing extremely high mineral content. 2. Usage: The ready-to-use formula is easy to apply and compatible with any type or model of automobile or light-duty truck currently on the market, as well as any existing antifreeze. It can also be mixed with antifreeze of any color. A 50% antifreeze mixture provides temperature and corrosion protection, while the remaining 50% specially treated softened water enhances heat transfer properties. Since no mixing, measuring, or adding water is required, simply pouring this product into the radiator or overflow tank immediately protects the vehicle's cooling system.
