I've seen alot of posts regarding winterizing for freezing conditions. Is there a standard guideline for "winterizing" for a temperature controlled building where we don't have to worry about freezing?

I'd still add antifreeze for the corrosion protection, and in case the furnace fails.

My garage has the furnace/heater set at 40* in the winter. I have not used antifreeze for the last 3 winters. RV antifreeze does not offer any anti corrsion properties anyway. I just add stabil to the fuel and do normal season ending maintanance. Also, I don't have to worry about condensation in the fuel tank, because temp changes happen slowly.

Better to invest in the glycol, just in case!!

I am envious of Griff. I need to get myself a climate controlled building!!

That's all I do but usually set the furnace a bit higher.. I had to add a dehumidifier to the building so I can maintain the humidity as well. (Not so much important in the winter months)

all it takes is a huge snow/icestorm no power for a couple days,i would prep it like it was outside in alaska,can't hurt and the cost isn't that much different. my .02 cents.

About the same, except I keep my shop quite a bit warmer since I work in there thoughout the winter months. One NG heater is forced air, one is infrared that requires no power, and the floor is heated so I'm not worried about an outage. I drain the blocks and hoses, but don't use anti-freeze. I perform normal end-of season oil/lube changes on engines and drives. I used to use Stabil many years ago but have found Pri-G to be a much better storage additive for the fuel (I have used SeaFoam a time or two with success as well).

Extended storage. You should prepare your boat to sit whether its indoors or out. Protect the fuel system. Protect cooling system and external surfaces from corrosion. It's best to drain and replace with an anti freeze like propylene glycol. To drain and leave dry is worse then leaving water in it as far as corrosion goes. For what little it costs it's foolish not to do the best you can with it. Sure you can get away with less, but why?

Kevin,

Even though I keep my building @ 50* all winter, I still winterize with automotive antifreeze. Never know when there might be an extended power outage. Not worth the risk of cracking an engine block.
