That is actually a big difference. I hauled hazmat for 17 years, mainly gas and diesel, with a bunch of propane and some natural gasoline thrown in.


So how would you feel about hauling a truck load full of pink antifreeze ?

What is Natural Gasoline ??

I just looked up the chemical compatability of Propylene glycol and rubber, it is listed as satasfactory. I have no issues using it im units, and neither do thougsands of rv dealers and service departments, its actualy recomended in my owners manual.

I actually did haul antifreeze and airplane wing deicer. The pink antifreeze would be no different in my opinion.

Natural gasoline that I hauled was used as a denaturant for ethanol, to make it undrinkable. It was very light in weight per gallon, compared to motor fuel gasonline.

Now that I went down a rabbit whole, back to the original post.

I have also had problems finding the non alcohol pink stuff. But since I drain my water, flush with pink, then drain that, I am not very worried about it. It just gets too cold here to trust only air. With draining the lines after the pink flush I have no problems with flushing in the spring, since there was almost no antifreeze left in the lines. The feel good thing I get from it is if there was an elbow that was a low point I don't have to worry about it cracking at -30 f.

I use whatever is on sale or easily available. This year (Covid) has made a big difference here. Only place I found , within reasonable distance was $10 a gallon. Only used a quarter of jug, rest was blown out with air. Prices on almost everything are up. Windshield washer fluid for the car is over $5 a gallon jug.

Tractor Supply here in Columbia, SC has it for $3.99 a gallon. Don't know if it is alcohol free or not.

Air is free beside the electricity to run my air compressor. Buy "ONE" gallon for the "P" traps. I never have or will put that stuff in my lines.

Chances are that those rubber seals are actually made of Santoprene. Alcohol has little effect on it.

I do the basically same thing. I drain, flush with antifreeze, and then blow the antifreeze out with air. I've been doing this for over 10 years on this Travel Trailer with no problems.
