Dex-Cool
For all of you with a GM 8.1L engine, do you still use Dex-Cool, or have you switched to standard Long Life anti-freeze in the cooling system?

I still use Dex-Cool and after 80,000 miles I see no reason to change. Since I do most of my own service work, I do not fear someone adding a coolant that is not compatible with my Dex-Cool.
