What’s the difference between 50/50 and regular dex coolant and which would be better for my 06 Colorado?? TIA

Prestone All Vehicles fluid protects the cooling system resulting in longer engine life. This is done by Prestone's Cor-Guard inhibitors. Dex-Cool is formulated to the guidelines and specifications outlined by GM. Both fluids will provide protection to your vehicle's cooling system. However, Prestone All Vehicles protects for 10 years/300,000 miles and Dex-Cool protects for 5 years/150,000 miles. Prestone All Vehicles provides superior protection. To fully maximize the benefits of the antifreeze+coolant perform a cooling system flush, clean and refill.
