AKA the most extensively proven and fielded coolant additive in history
What's the problem here? You do know 2-EHA is used in many different coolants, not just Dexcool?
It's one of the most proven OAT additives out there.
The old GM problems are history and weren't caused solely by the coolant used.
2-EHA may be proven at this point, but it’s NOT what those manufacturers want. Specifications mean something, they’re there for a purpose. Someone might try to swap something else in and be ok... but the outcome might not be what is desired.
I don’t mind Preston products, but when something is pushed on folks as one thing, and it’s a different thing, that’s an issue.
