Remember "Permanent" Anti-Freeze


Hard to believe back in the 1950's we were so cost conscious we use to think it was a big deal if we bought "Permanent" anti freeze. Anyone under 50 of course will have no ideal what I am talking about. The non-"Permanent" anti-freeze was an alcohol based antifreeze (desperate people tried to drink it) and was a lot cheaper than the Ethylene glycol antifreeze which was considered permanent. As the higher powered cars came on the market the engine thermostats temperature went up to 180 degrees so the alcohol based antifreeze would boil away, since they were best down around 140 degrees.
