Which coolant is better? I have been looking at Fleetgaurd's ES compleat line. I don't really want to use the Fleetcool becuase I would rather have the DCA-4 over the DCA-2(just my personal preferance since the Ford stuff is the same as the DCA-4). I know that the PG is less toxic than the EG is to pets and whatnot, but will the PG attack gaskets or o-rings or is it ok.
