I just drained out some nasty water from my car, as it will be in my unheated (when i'm not in it) garage I needed to put in some antifreeze for the winter storage season. My question is what is the best summer coolant to use when I drain this that will not cause excessive slickness in the case of a coolant loss on track?

I know 100% distilled water is a simple alternative, but it can cause other issues that coolant is designed to help with. Corrosion, water pump seal lubrication, better flow, etc. It looks like all of these will work and be safe on the track, any suggestions?

In looking quickly for alternatives I see;

"RaceCool" - https://www.alligatorperformance.com...FdgUgQodLqwGwg

"PurpleIce" - https://www.kseriesparts.com/cr/RP-0...FZM7gQodv8oNYA

Summit Racing's "Ice Water" - http://www.summitracing.com/parts/lqp-0699/overview/

And of course good ol Redline Water Wetter - https://www.pegasusautoracing.com/pr...FZM7gQodv8oNYA

or premixed as "SuperCool" - http://www.summitracing.com/parts/re...FYQlgQodMO0F6g

Not sure of the logic of "Supercool" pre-mix as one $10 bottle of Water Wetter treats our 4 Gal cooling system.. I would simply put 1/4 bottle in each of 4 gal. of distilled water, shake it up and dump, no?

OK, no input so i'm going with the one I didn't list that says it increases horsepower...

Garry - go with Water Wetter. Works for me and adds about 5 hp.

I'll get 7.4% out of mine with a 25% reduction in head temps.
