You should be fine as long as you don't mix anything other than dexcool with it. Just make sure the cooling system is topped off and doesn't aerate. too much air will make it foam up and turn to mud. Almost every vehicle on the market today uses a coolant based and the poly-glycol in dexcool. The problems with dexcool had to do with how people where using it. it is not a liftime coolant it's only good for about 2 years or 50000 miles.
I would run it, it's not going to hurt anything at all.
