Thread: How many people still use Dex Coolant

I too will not use the green...I do use the universal prestone.
regardless you have yet to give me solid reason as to why dexcool is good, in fact you have only convinced me further of it's problematic issues, say its faulty gaskets, well perhaps the gaskets are faulty because of what they retain.... and yes the acidity is caused by the air getting in, but wouldn't you rather use something that doesn't turn to acid????
once again i will post this just this one link, i know the guy who took the time to put it together.... please check it out, and read through everything...same type gaskets, with the dex ones having much lower miles then the other and yet they look much much older.... the results speak for themselves
The potential role of DEX-COOL®

Dexcool has not caused issues in other cars besides the 60* V6 family and the 3800. Two families of engines known to develop leaky gaskets no matter what coolant you run.

Why doesn't it leak in the Corvette? The Solstice? The Tahoe? The Escalade? Saturns? The list goes on. It is because of faulty gaskets and Dexcool is the scape goat.

This is true. Whenever I need to add coolant, I add the Prestone. But, I haven't been in a rush to flush because my Dexcool isn't giving me any problem because I keep it well maintained. I'm probably a little over half and half between Dexcool and Prestone by now since I did my gaskets.

I have seen that link before, and I've seen gaskets like that on a L67 that had the Dexcool removed after five miles. Those gaskets fail like that, end of story. Not because of Dexcool, but bad design. I refer you back to my argument of why every GM engine doesn't have gasket issues then? The same material was used across the board.
