A heads up, Peak has changed their 10x into a Dex-Clone instead of the previous pHOAT formula:
It looks like the non-2-EHA pHOAT inhibitor package lives on in Peak EcoShield and a new Peak Titanium on OWI’s website. For those who are avoiding 2-EHA, you have been warned. It might not matter in many cases.
I’m going to use Peak Final Charge Pro Series in my Toyota applications, my test car using Prestone hasn’t lost coolant, but I’m switching another car I had Cor-Guard in to Final Charge. I noticed a mysterious coolant level drop in a year and half - it might be evaporation FWIW but knowing Toyota’s love of RTV FIPG to seal water passages(or almost 20 year old radiator tank seals/bypass gaskets about to cry uncle) I can’t be sure.
