I don't care about brands unless my hydrometer complains. As long as I've got a hose nearby, I'll take whatever 100% green is available.

a/c delco 50/50 dexcool all the way. Its made with lubricants to help the water pump. As long as you do you required flushes (90k miles on most GM'*)(But i like to go every 45k) you will have no problem. I'm big on using OE products becuase thats what the vehicle was designed to have in it.

LOL ... I admit there are a few exceptions but being a GM tech, I have seen waht kind of damage can happen when something other than what is recommended is used, be it parts or fluids.
