Dexcool vs. Conventional

Good Evening, I have a few coolant questions that have been asked before. I have been driving my '93 RMW for a year, and I've put 10,000 miles on it, and its been great. The other day I was low on coolant, for some reason, the 2 years of owning the car we never checked the coolant, so my dad and I noticed orange coolant (Dexcool) at the bottom of the reservoir, he had me fill it back up with the dexcool we had from another car. So I think at one point a dealer decided switch to dexcool, and the previous owner had them start using that. Is dexcool ok for my '93 MRW? I think its time for a coolant flush soon, if I do, should I go  convential or dexcool?

Thanks, hopefully its been completely flushed out, and completely with dexcool, but next time I get the coolant flushed, Ill most likely go with el-cheapo. Yeah though, when you mix the two you get the orange sludge(Dexcrap?), and it can blow head gaskets I heard from someone.

Don't go by the reservoir, it can look orangish from rust build up. Take off the rad cap and check the colour.

Auto zone has a yellow coolant that can be added to either....... Use up the coolant in the jug, refill with piss, and return defective (smells like piss)  coolant to "the zone"!
Once the chemists figure out what you returned (piss) they can distill it, dye it blue, and re-sell it as DEF (diesel exhaust fluid).....

I worked at a GM Dealer from '94-'01 as a tech, and Dex-Cool caused a lot of issues, but those have all been addressed since '03 or so, so no worries at this point. Most of the coolant out there at auto parts stores, and department stores carry coolant that can be used with either coolant. I use green personally.... Posttraumatic Stress from the hundreds of intake gaskets I did on Dex filled cars.
