Dexcool is a great product ONLY if it is put in a new engine at the factory because at that time it will seal the metals at that time. That is why you must keep using it. That is also why putting Dexcool in after the green stuff does nothing and will NOT last the 5 years.
Changing it at 30K is fine with me.
My goals were:
a) to use a silicate and phosphate free antifreeze
b) to use an antifreeze that meets the spec number under the hood.
The Havoline Dex-Cool met those specs.
It was also cheaper than regular Prestone.
But, I ended up taking back the DexCool and got the Prestone anyways. So, no orange stuff for me this time I guess.
