It doesnt matter what kind you use, as long as you don't mix different types (ethylene and propylene glycol) of coolant. Personally, I use the green stuff (Prestone), but I perform a complete flush every year on my vehicles. I will drain the AF out, then fill with DI water, run it then drain it again. Repeat the process until the water is clear. Then I fill with the new coolant. This process will ensure that your coolant is completely removed from the block (which is not done with a simple drain and fill).
