I have always used Zerex Pre Charged HD in my equipment. Its the old school green Ethylene glycol that came in the machines so that's what I put back in. It's cheap but I have found I have to order it online as no one around me carries it. I figure continue to run whatever it came with.
I have thought about changing to a newer Extended life coolant (the old stuff is marked that it's only good for 2 years) but I'm always afraid I won't completely get it out of the passages in the block, water jackets, etc and end up screwing it up. So I just run the old cheap stuff.
