Winter Freeze Protection

Changed the anti-freeze in my 961 getting ready for the cold weather just around the corner and brought home a portable refractometer from the plant to see where I'm at. Looks like the mixture is just right. Good to around -40F.. That should get me thru just about anything mother nature can throw at us here in Northern Illinois. Hardest part was getting a clear picture thru the eye piece with my phone!

I picked up a couple of gallons of RV antifreeze at Orschleins today for my three point sprayer.

Anyone remember alcolol (non permanent) antifreeze, commonly used in automotive, etc., engines up into the 60s?

I remember my dad using it in an old Oldsmobile but that was before I started wrenching on things......
 


I have not been comfortable with the float type testers for a few years now. I should probably get a refractometer.
 
I remember my Father using it in old cars in the mid/late 50s.

Even then, I was a motor head and followed him around as he maintained anythng. I remember him telling me that "permanent" anti freeze would not "boil out" as did alcohol based non-permanent anti freeze but
cost much more. Accordingly, he used permanent anti freeze only in the "good stuff." The old stuff got alcohol or H2O.

I remember it & it smelled better than ethylene glycol.
Easy as pie to get correct protection...just follow the mixing instructions on the bottle! Duh?
 
Sure do, it was likely the only thing you could buy during WWII. I recall one fall when we had nothing, harvesting crops meant use the tractor and drain it dry when done. I recall dad asking me at supper time if I had done so, answer was yes, reply was better go and check it again. Also, recall folks doing early spring tilling would boil the alcohol out, next it would unexpectedly freeze again and they lost their block. 9/2/8N's came with 160 degree stats to help prevent alcohol evaporation. True also was that many folks thought that they could not afford permanent, some were. It came in expensively in tin cans where alcohol was $.10 a gallon in bulk bring your own container.
 
I'm picking up 16 gallon jugs of RV antifreeze tomorrow at my local Walmart. It's for my RV, to winterize it at the end of the season (end of October), but it seems to be getting scarce this year, just like everything else because of this nnalert thing, so I'm stocking up now. I ordered and paid for it on line today so I know it'll still be there when I go to pick iit up. Already received my confirmation email that my order is ready. My RV only took 5.5 gallons last year to winterize, but this year we added a washer/drier, so I'm buying way more than I'll probably need just to be sure. It is propylene glycol rated to -50 degrees.
 
Not on original topic. My RV is a 2005 and is plumbed where I can flip a valve and suck RV antifreeze directly from a container instead of pouring it in the tank. I can winterize the RV with less than two gallons and that's overdoing it. Valve is between water tank and pump and is a bypass valve identical to the one at the water heater.
Just trying to help.

Mine has a valve setting to use the pump to suck the antifreeze from the bottles into the system as well. Mine probably has more pipes than most. It's a 38" class A with a full bath plus a half bath, plus a washer/dryer as well as the kitchen sink. It can probably do with about 4 gallons to fill all of the lines except the washer/dryer, but I let it flow out of all of the faucets and through both toilets for a little while as well to get some of the antifreeze into the gray and black tanks (2 of each) as well. This being my first RV I guess I'm a little paranoid about pipes or tanks bursting.
