Testing Propylene Glycol Antifreeze
Did you know that the freezing point of propylene glycol antifreeze/coolant cannot be tested with standard coolant testers designed for ethylene glycol? Ethylene glycol testers will not deliver readings for propylene glycol formulations.
Specific testers for propylene glycol are available at reasonable prices from many auto parts stores. Another testing option is disposable antifreeze test strips. This inexpensive and convenient method provides accurate freeze point and pH readings in both ethylene and propylene glycol. We can offer these in packs of 6 or 50. Contact us for more information.
AMSOIL offers a non-toxic and biodegradable Propylene Glycol Antifreeze & Engine Coolant that combats corrosion and extends service intervals in gasoline and diesel engines.
