In the frosty aboreal climes along the Great Lakes, the Coolwell-supplied

solutions may work fine. But in the miasmic subtropical swamps bordering

the Gulf of Mexico there are "bugs" that will even eat the diesel fuel

right out of your tank as you drive. There is also a slimy, lower life

form (which we have not identified) for which anything containing nitrogen

(including the Coolwell solution)is fertilizer. After battling this blob

from the black lagoon for more than a year we have found that it takes at

least an 18% solution of lab grade ethylene glycol to give it indigestion.

(It will ignore a 10% solution).
