" yeah... I'm running the NAPA equiv. in my Classic now.

napa has an equivalent?!?  i know they must have propylene glycol
antifreeze, but evans coolant is almost pure propylene glycol with no
water.  since it lacks the heat capacity of water [nothing has the
heat capacity of water] you need a higher-temp thermostat - 225? - and
since it boils -way- higher you're supposed to run a zero-pressure rad
cap.

btw i was very impressed - evans did some rigorous, journal-published
medical research showing that 10% admixture of propylene glycol to
ethylene glycol rendered it nontoxic - to humans at least.

you're thinking of redline 'water wetter', which racers use in lieu of
antifreeze.  it also has water pump lube.
