How much propane do you lose out of a tank
in five years or longer?
If I put a large tank of propane on my BOP.
Do not go back for a long while, how much
would still be there?
How about out of a 1lb tank?
25lb tank?
Yes! I know rotation is best!
Thought, someone should know the answer.
Thanks for any info.

Unless your tanks have holes, all will remain.  If it has a leak in that time period it will be empty.  You can keep tanks full for your lifetime if kept from rusting.

ETA rotation is not needed unless you suspect the tank is getting in bad shape and could leak.

What has been said.

Protect the exposed steel parts of the tank, like where the valve screws in or any scratches, with anti-crossion spray or paint, -NOT WD-40!

Inspect from time-to-time carefully.

If protected, they will outlast you.

Semi-related. Do NOT use those exchange a tank things like Blue Rhino. Theyre often used in producing meth and the chemicals eat away at the tank making it very unsafe(I would not trust them to do proper pressure testing etc..)

Not to mention you don't get the amount they advertise.

This is true but in most areas but I believe the anhydrous cook method is starting to fall out of favor as easier methods have been discovered. If the brass fixtures on the tank are blueish/green then dont touch it!!!
Damn meth heads.....

Not totally true.  The Blue Rino tanks are tested and you can tell quickly if the tank held anhydrous ammonia.  No tank filler will put propane into a tank that held anhydrous.  The Blue Rino tanks are safe to use.

On the other hand, as another poster mentions, Blue Rino doesn't fill their tanks to full capacity.  I always take my tanks to a local refiller.  It's cheaper and I get a full tank.  

And, as mentioned, as long as the tank is kept in good shape, the propane will stay in the tank forever and be useable forever.

On another note, where I live propane is the cheapest it has been in a long time.  $1.39 per gallon at the moment.  Good time to top off those propane tanks!!

While we are on the subject of bashing blue rhino, heres another to stir the pot. The *new* blue rhino tanks cannot be refilled, they have installed a special check valve which requires a propriety triangle key to allow the tank to be filled. Pretty clever. Therefore, when you trade your tank in for a blue rhino, you are stuck with them, unless exchange the blue rhino tank at another retailer.

Blue rhino puts 17lbs of propane in a 20lb tank, they claim its for safety reasons. But that is complete bull shit, you cannot overfill a new style tank with a opd valve.

Personally I wouldnt want to bet my safety on it. I'm sure that their policy is to check for liability purposes, but does that mean it gets done all the time? My luck I'd get the one time that it wasnt check

I've bought several brand new 20lb tanks from Costco in the last two years.  Bought another yesterday for $25.  Add $10 to fill and that's a pretty good deal even compared to swapping out which runs about $20-$25 here.



They had a 100lb tanks earlier this year for about $90 iirc.  Should have bought two of those.

Walmart will take any tank in any condition for trade for a 'new', tested tank from AmeriaGas with 15 pounds of LP in it for about 18 bucks.  I'm cool with that.
