Car is driven in the Northeast, both on the street and on track.

Car currently uses 50/50 mixed with Water Wetter.

Car is approaching 60k soon, and will be going through a coolant change.

Looking for opinions on what to use for this primarily street driven car:

Evans High Performance Waterless Coolant
50/50 with Water Wetter
50/50

I know the adage, if it ain't broke, don't fix it, but would like to have some thoughts on these three choices, or any others that I might have missed.

 

Due to what I understand is a good coolant system from the factory, I don't think it matters. I use 50/50 with water wetter or purple ice. Live in Texas and seems to be good.

 

water wetter isn't needed on a 50/50 mixture and is less effective the higher the concentration of antifreeze is.

From the limited research i did on evans, it has a higher specific heat than antifreeze, which means the ability to cool will be reduced. Not great if you track, but not a big deal if its a DD/autocross car.


If you do like to track, but must keep anti freeze in your system, i'd reccomend the standard 50/50 with the motor max additive. The stuff is thinner than alchohol and dissipates heat just as well, maybe better. Really increases the ability for coolant mixtures to ditch heat.
