When I got back home I checked my Prestone Extended Life Antifreeze bottle.  It says:

1. May be added to the antifreeze/coolant of any make or model auto or light truck on the road today,     foreign or domestic.
2. May be added to ANY color antifreeze
3. Protects aluminum and all other engine metals
4. Provides extended life protection for up to 150,000 miles or 5 years

This is definitely not Dex - what ever that brand is!!
   
I first ran across the Prestone extended life (orange in color) when it was in the new C35 (M35BC engine) that came from the dealer. 

I wouldn't immediately rush out an change my antifreeze, but if you were to change a hose, replace a riser or have some other reason to drain the antifreeze - I'd replace it with the Orange Extended life.  Also remember to dilute with distilled/rain water, so the chemicals in tap water don't change the chemistry.
