RV antifreeze

The Menards antifreeze, Splash branded, has both propylene glycol and alcohol. I've used it for a few years and haven't noticed any ill effects.

I bought boiler anti freeze, rated for 100 below, several years ago at an RV close out for. $1 a gallon. Deluted by half for a net of 50¢ a gallon. Just ran out. If I wold have gone to the blow out method then I'd still have a bunch.

If it is marked with the Flammable sign on the bottle it is alcohol. I have heard that alcohol based antifreeze will also leave a bad taste in the plumbing that is nearly impossible to get rid of.
The good stuff does not have the Flammable sign and cost about double, and is safe for the environment. I think it is made with glycol instead.
Oddly my RV dealer was telling me that they did a taste test in the shop one day to prove that the glycol based one is truly safe, and apparently Camco was the best tasting :)

Bomgaars had it for sale at 3 bucks a gallon in Spirit Lake, IA

$3.49/gallon is no great deal. I try to catch it around $2/gallon.

I didn't know the point about alcohol in RV antifreeze being a no no. Is the stuff sold at CW best? (I don't care if it costs more)

Ollies Bargain Basement had it for $2.99...

Careful with the cheap stuff at Wally world...it contains alcohol and can dry out your seals.

All RV antifreeze is not created equal. Some even comes as premix. Make sure you read the labels before comparing prices.

We bought some yesterday at Menards in Port Huron for $ 2.50 a gallon.
