There is a very good reason that our stock car rules mandate water only 
in the rad.  The waterless coolants provide a HUGE advantage over water 
based coolants in high performance situations.  That said, I've never 
ran it in my highway stuff... In my lifetime I have had coolant issues 
four  times.
1.  lost the block heater going up the big hill to Flagstaff in an 82 Jetta.
2. popped a rad hose sitting idling on the concrete pad parked out in 
front of my shop (no kidding) on the high mile 89 jetta. (top hose failed)
3. lost a rad hose in a combine- fan blade erosion in an un-inspectable 
spot.
4. had intermittent heating in the 89 jetta when I got it.  Turned out 
to be a soft lower rad hose collapsing under higher engine speeds 
causing the water pump to pull a higher vacuum than the soft old hose 
was capable of withstanding.  wound a spring out of stainless tig wire, 
problem solved until I changed  the hose out a year later.

that's it.
I can't persuade myself to run Evans coolant because not one of these 
issues would have been prevented by it's use... maybe item #2 due to no 
pressure, but the failures were all mechanical in nature, and should 
have been caught by me on inspection.

Let me run it in the stock car, now you have something.  That's a 
perfect application for it- I can come in off the track at 240 with a 
heat soaked engine, and smile, because it's no big deal.
