Does anyone know of an equivalent Antifreeze I can use for my engines other than WM Pure Oceans? It's not that I'm opposed to their stuff it's that their is no local WM/marine stores near me? So if you know or use something just as good I'd like to hear.

Thanks -
 
I assume you are looking for the ping rv antifreeze - propylene glycol vs ethyl glycol antifreeze for winterizing? I found Prestone propylene glycol at Walmart for $3.49/gal, where the Walmart brand is a little cheaper, but contains ethyl (alcohol) glycol.
 
The key is to find one with zero alcohol. Prestone makes rv/marine antifreeze that is propylene glycol, no alcohol - sold at walmart and other places.
 
WM will ship it to your door step for free if you order two cases (12 gallons)... I got mine in 2 days.

(Free shipping on orders $49+)

West marine ships for free as well over $49. Took about 6 days for it to arrive.
 
I got mine at Walmart too! The Prestone at 3.49 a gallon is the one you want for the motors because it has no alcohol in it, and it does have rust inhibitors. Don't use the cheaper stuff in the motors.
For the fresh water system, head, and AC, I got the pink from ACE hardware on sale 2 weeks ago for 1.99 a gallon. Not sure if that sale is still on, if not, then the cheap pink stuff at Walmart is the way to go. I think it's 2.49 a gallon.

There are 3 West Marine stores in the Annapolis area.

Just bought 10 gallons at Walmart near Atl for $3.97. Regular w/ alcohol was $2.99.
