I switched everything to Peak Final Charge Global. Google their site for all the details.
Reason.....it is compatible and can mix with all types of green and ELC and does not require a flush. As long as you can get 70% dilution it is the same as 100%.
Makes it very easy to switch, then you can run one brand in everything. It does not require additives and I think it is good for 12,000 hours before you have to test.
