So to summarize

Pink (11) vs Blue (3)

Pink (-50) there are two main ingredient types;
Ethanol (aka Alcohol) or Propylene Glycol

Blue (-100) also uses Propylene Glycol, just a higher %age.

Possible issues with using Pink (Ethanol based Antifreeze)
  1. impact on rubber seals and plastic in the water system
  2. residual taste even after flushing system
  3. lower flash point then propylene glycol. 110 vs 200 something

Another issue not brought up but discussed in the link Tech Tips: RV Antifreeze: Not All the Same - RV Life Magazine is whether the materials used are recycled vs virgin.

Conclusion:

Best value, cost vs function for RV'rs is Pink (-50) using propylene glycol. Some also may be mix it with Glycerin * or Glycerol ** unless temps get close to -50 and then would opt for the Blue (-100)

Brands using propylene glycol and percentages

Dowfrost ** 18-21% / 11-13%
Super Tech (Walmart) 30%
Splash (O'Rielys) * <20% / < 20%
Prestone 20-40%
Polar 25.5%
WinterCare 40%
Camco EasyGoing ???

Percentages based on MSDS sheet

Brands using Ethanol

Camco Artic Ban
Peak
Zecol (Lowe's)

Not sure about the alcohol content but the mint stuff is horrible, imo. It can permeate pipes and pex lines and the flavor can linger long after it's drained and flushed. Nothing worse than minty coffee in the morning

We're heading for Brown County today, our last trip for the year. Hoping the rain ends very soon tomorrow. Will winterize next weekend. Following weekend I'm moving my business to a new location.

I have always used the pink stuff, cost roughly $4/gallon around here. I also blow out my lines.

No problems that I know of.
YMMV
Have to correct myself-- looked in my garage at some old empty jugs.
Most all say "does not contain alcohol". I just never paid attention before now. I usually pay $2.50-$3 for these. Hate to hear some of you guys
are paying North of $4 or even $5 for it!

Recently (this month) bought Meijer house brand and it says no alcohol.
Sent the wife back for more on her weekly shopping trip and she came back
with CM tech group redish orange that says - contains propylene glycol, glycerine and ethanol. Guess they are covering ALL the bases!
