The Toyota Long Life Factory Red Antifreeze Fluid is: Ethylene Glycol, diethylene glycol, and then the third listed component is water. Exactly the same is printed on Prestone. However Toyota states that it contains no silicates (that may harm water pump seals) and no borates (that may cause aluminum corrosion/pitting) Prestone also states that the additives in it protect aluminum corrosion.
I believe the two are very very similar or maybe even the same exact product.
