Summerizing my Greyhawk

[ErikB]

Summerizing is MY version of de-winterizing☺️ And I’m wondering about how many gallons of antifreeze it will take to winterize my 2013 Greyhawk. Can anyone give me an estimate? 5 gallons, or more?
Thanks in advance

I used to do all my rigs with 2 gals + All you need to fill up are the pipes and the traps. You bypass the water heater.

I always buy 3 gallons. A good part of a gallon goes into the onboard filter.
.
I always blow out the lines with air first, at 30 PSI from a large compressor. I found something interesting, though--- After I blew out the lines with air, I opened the filter housing, expecting to dump out the remaining water so it wouldn't dilute the antifreeze. But there was no water in the housing. Somehow the filter element in combination with the air flow, wicked out the water. Strange.

I always buy 3 gallons but barely touch the 3rd gallon as I have at least 1/2 gallon left over

If I'm stingy, I can do it with two. But I plan on 2 1/2.

Mine takes 2, I buy 3 to use the other one to rinse the toilet when traveling in freezing temps to Florida.

Well,...I had already purchased 3 to use this next fall, but was second guessing that was enough. Guess it should be,...if I'm efficient

Thanks for all your replies!

Around here, Walmart will have it marked well down come spring and summer. I usually stock up then. In preparation for the next winter.
