Antifreeze

------COST !!!!!!!!!! --
-- Yep !! -- Near $50 per gallon, plus the PITA of prep, at Around $25 per gallon. --- And -- Who cares about boiling at 375 degrees. Your motor will cook long before that. -- Who needs minus 40 degree protection ? -- Zero pressure can mask leak problems, warped heads etc. -- Antifreeze with 50% water (minus 34 degree protection) and a bottle of water pump lube does the job quite well.
