They mix fine, but if the Prestone is supposed to be five year, 50,000
mile "new technology" coolant, it won't last any longer than the regular
stuff if there is more than 10% of it in the mix.

It is best to stick with one brand since the corrosion inhibitor
additive packages are all a bit different, and there is no guarantee
that mixing brands won't reduce corrosion protection.
