Why the large discrepancy in rv antifreeze prices?
I've seen prices as low as $2.50/gallon to as high as $15.00/gallon or more. Is there this much difference in performance?
Forum Discussion
Some RV antifreeze are ethanol (alcohol) based, some are propylene glycol based, some are a mix of the two. Ethanol is cheapest and propylene glycol is highest, normally.
And some stores just charge more.
Some people have concerns about alcohol and rubber seals.
