I have some questions about Amsoils' ANT Propylene Glycol Antifreeze. I haven't sent an email to Amsoil yet, I wanted to sound it out here first. I just switched over a 97 Escort to the Amsoil ANT and have noticed a few things. The car was flushed with distilled water using a gravity tank and a flush tee in the return heater line. Then the 4 1/2 quarts of ANT was added to the tank and allowed to pour into the vehicle. A small amount escaped throught he filler neck after displacing the distilled water and the system was closed up and run until warm. This should have provided a 60% solution when fully mixed. The car was driven for a few days and then the antifreeze was tested, it came in at 20% soultion on a snap on ball tester and 40% on a refractometer. After a little calculation 8 oz of ANt was added to bring the solution to 60%. The car was driven a few more days and the antfreeze was tested again 30% on the ball tester and over 70% on the refractometer. I would think the water pump would be the best mixer. Now jump to this evening, I had to replace the thermostat as it was acting erratic. I drain all the coolant from the engine short of pulling the block plugs and it still tested at over 70%, then I sucked all of the antifreeze out of the coolant recovery bottle and it tested as almost pure ANT, it went beyond the scale of the meter which tops out at 88%. I have now added both fluid together and balanced with mixture to 63% which will give me freeze protection to -55f. We will see how it tests in a few days. The questions I have are:
1. Is PG that hard to get a good reading off of, I have tried 5 different ball testers and none read the same, from 20% to 80% off of the same sample. The 3 refractometers we have are within 1%.
2. I know antifreeze is colloidal and mixes with water, but does PG have a tendancy to seperate out more the EG. When I was balancing the solution in the drain pan, you could see the added distilled water make some neat swirls within the PG before it fully mixed.
3. Is this a problem with only Amsoils ANT or does it effect all manufacturers.
Any thoughts would be appreciated. Thanks!
