Sure you can. You can also use straight tap water. It just isn't recommended

It is not recommended to use tap water in a cold area since the water could get frozen. LOL

The terrorists win.

No, really though, the only things I know about the two is that they're different chemically, they both protect against corrosion, its bad to mix them, and the orange is longer lasting.

If you are going to do a drain, might as well swap the thermostat at the same time.

The Toyota engineers would say their formula provides the necessary properties to maintain proper function of the various components. I've seen the reservoirs of enough Toyota's filled with all kids of different coolants. My Celica has had Prestone, Valvoline, Dex Cool and when I do this next round, I'll use Toyota. For the LS, it is just as easy to buy a jug from Toyota and know this is the Toyota recommendation.

guy at the shop is an idiot, the green and red and etc. colors are generally very different in addititves and base compositions. should NEVER mix them, and some are suited for iron/alum/plastic heads/intake.
