What color Antifreeze!

What color Antifreeze has the best rust inhibitors?
I have seen alot of bad freeze plugs, and Dual Climate control valves (DCCV).
All Makes and models Prestone long life 5-year/100k miles is probably the same as other dyed
organic antifreeze.

The Prestone old Green isn't enviroment safe.

The pink/100,000 mile coolant has superior rust inhibitors, but I have also read there has been problems with the pink stuff deteriorating the radiator hose if it's left in for 5 years. Some still use it, but change it every 2 years as they would the green to prevent deterioration it could cause.

Stick with the "color" that's recommended for your vehicle. They're formulated or specified by the vehicle manufacturer to work best with your car/truck. Changing colors, especially without completely flushing the old stuff out, can cause the two types to interact, gel up, and clog your system.
