Been doing as much research as I can on this topic. I'll try to keep things brief.
To start, it's really surprising how complex coolant is. From an outsider's standpoint, there only colors - green, blue, red, etc. - that's about the extent other forums take it. Not including the water choice, DI, purified/RO, tap, etc., the additives/packages/chemicals in coolant alone can be overwhelming as far as what your car "needs."
So, for a 2006 Mitsubishi Evo which sees very few miles yr and sits all winter, as far as I can tell I'm thinking:
1) Flush the system using RMI-25
2) Run Zerex Asian Vehicle Anti-freeze coolant (http://www.valvoline.com//products/brands/zerex/antifreeze/105) mixed 50:50 with demineralized water
3) Flush every year
Originally I was thinking of making the switch to Evans waterless, but it doesn't seem to perform that well in reality.
Thoughts on this?
