Can RV anti freeze be re-used?
Last year when I drained my anti freeze, I put it back in the original bottles. Can I re-use the anti freeze, or is it not advised?

I am far from being an expert on this, but I see no reason why not. My maintenance guys recently drained my the radiator on my pusher and reused the antifreeze, so if automobile antifreeze can be reused, don't see why the pink stuff could not as well.
I don't normally have enough pink stuff to make it worth while. I blow out my system with air, put pink stuff in until it runs through all the faucets, run a little into the water heater and the fresh water holding tank, then blow it out again. That second blowing out eliminates a lot of the after-taste of pink stuff.

Well the antifreeze in the Pushed Diesel is a lot different than the pink stuff.
#1. That Diesel Pusher has a huge cooling system, so if the antifreeze was clean and not too old your mechanic save you a lot of money at about $10 to $15 per gal. for automotive antifreeze.
#2 the pink stuff is cheap, as state you can get for less than $3.00 per gal. if you watch sales. I never used more than a gallon in the old 28' 5er. We don't use in the new rig, except for the drains. If I did it would be less than two gallons. It is not worth the effort/risk in my opinion.
