Another article I read online awhile back was saying that there are times when technological advancements are made in an industry (like the automotive industry) and the current support or technology has to "catch up" for it to work properly. The most recent thing that comes to mind is the switchover to digital tv. The digital tv was a newer technological advancement over analog, and in order for people to take advantage of it they had to either buy a newer digital tuner , tv, subscribe to cable/satellite, or buy a digital converter. The same can be said for the Dex Cool issue. Dex Cool is a "newer technology" but the remaining items, (gasket materials, designs, etc.) are still the "old style technology". In order for everything to work in unison, the older technology items also need re-working and upgrading which either didn't happen in time, or were poorly planned and executed. By this I mean the LIM gasket materials and design, and properly educating consumers on how to maintain the coolant, etc . Advancements have been made in order for everything to work together and time will tell if it has been successful. |
I think Dexcool is compatible with convential green but I'm not saying anyone should top their cooling system full of Dexcool with green. I meant if you drain most of the Dexcool out, you could switch to green if you wanted to. Dexcool and green are both ethyl glycol based only the additive package is different, with Dexcool being an OAT like you said. My thinking of why people believe that mixing the two leads to gumming is probably from cases where they were adding green to a system that had a leak and other problems that were causing the dexcool to gum anyway.
