I have a '99 Chevy Tahoe and almost two years ago did a good flush and re-fill with the green stuff. Talked to a mech. friend of mine and he is totally sold on going "gren" but really emphasized (sp?) about doing a good flush. At the same time I put in a new thermostat (195 degree) and a re-useable gasket. No problems and runs cool in the summer and great heat in the winter.
