[Solved] Refueling 11 kg Gas Cylinder: Conflicting Capacities & Safe Refueling Amount (80% or 85% Rule)

Hi everyone. Listen, I've read various forums and some say that the 11 kg cylinder contains 22 liters, the second 20 liters and the third 27.2 liters. Considering that the 11 kg cylinder actually holds 27.2 while maintaining the current rule when refueling no more than? Exactly. Another question arises, some claim that it is 80% as I wrote above, while others say 85. Let's stay with 80. So:
27.2 - 5.44(80%) = 21.76
So the safest way to refuel is 20l.
Worse, if the true hypothesis is 11 x 2 = 22l of gas, then with the 80% rule, it comes out to 17.6 liters, which is 15 safely. So a question for you.
Which of the hypotheses is actually true. I care about the answer. I filled up with 15 L today. I didn't want to risk it without being sure which school was the real one. We know how it could end ... By the way, when buying a cylinder at the station, we have the full value there (27.2) if so, why, considering that it is actually 27.2, ordinary Mirek refuels 20. Anyway, I will be grateful for help how much can i refuel. And what theory about the capacity of the 11 kg cylinder is true?

I immediately say that comments like this are forbidden, please keep to yourself. If I didn't have to, I wouldn't do it. The times when you paid 50 for a cylinder are gone now the price at the station 120 and transport 150/170. Cool? Inflation... See how much you can save.

Ps: I already have a refueling adapter. ?

Thank you in advance and best regards.

Is it possible to refuel at the gas station? On those who have been, it probably says on all that they do not refuel into the cylinder. According link a liter of LPG weighs about 0.52 kg.

On the cylinders that I saw, it was written on the rating plate how much capacity they had, and from what I remember it was something like 27 l.
How much to refuel? Well, about 22 l, because it can be more per kg, because the Propane-Butane mixture has different densities depending on the season, in winter it has a lower density because it contains more Propane, which has a lower density and lower heat of combustion than butane.

Or maybe this bottle:

I saw. But I have a better offer, so I was just looking for a cylinder with a safety valve and found such a bottle.

But I was thinking about a 100l tank or a tank from a car installation

The station doesn't really fill up. You refuel yourself. There is also a ban on them. But there's a perfect station near my house.

So 22L will be great in winter as well as in summer. Thank you.

Only 22lx3.4, you get 74.8 ... In casto gas for the cylinder, it's PLN 57, where is the point of this ... I'm asking because I really can't see ...

I'm of the same opinion, unless you want to be a hero in your yard.
For many years I have been of the opinion that you need to earn and not save and so far it works.

Some cylinders have a number 27 with a hook on the handle, and about 14 kg fit under the cork.

Hello.
And why not put the cylinder on the scale, tare and pour 11 kg?
Regards.

Have you been following this post from the beginning? The author wants to refuel at a station where it is FORBIDDEN !!! And what else is going to add weight...

Well, since it is forbidden and refuels, the weight does not bother me at all, apparently this friendly station.
Another thing that surprised me was the prices listed there. Yesterday and today I looked at the nearby gas stations LPG prices 3.20-3.50 Yes, about.
11 kg cylinder prices from about PLN 64-80 even. So the differences in replacement or refueling are almost zero. At least in the south of the Silesian Voivodeship.
It's better not to fall into the trash. buy cylinder cylinders from the car. Add an original filler neck and refuel with less risk?
I know about the cylinder, even without a certificate, it's hard because the neighbors from Ukraine take everything away. They can be without legalization.

Regards.

I don't know where you live, but in my area such a cylinder costs PLN 70.

I always took 0.6 kg=1l of gas. I refueled 20 liters, sometimes in winter 22.
The weight of the refueled cylinder and the replacement one is different.

Because this inscription usually with paint or marker on the cylinder 11kg is the weight of the cylinder itself.
This is so that the guy refueling at the bottling plant can see how much the cylinder has and how much he should show after refueling it with 11 kg of gas.
Just made a test today at a friendly gas station - with 12 cylinders after weighing with a bathroom scale because I had such differences in refueling in the range of 10.8-11.3 kg per cylinder plus iron.
A little surprise there are cylinders in racks as 11kg for pica and these are cylinders for trolleys. The staff often gets it and puts it in another rack - no one has taken it from them yet as a trolley - as part of the comments.

The faces of people refueling and watching us weigh in are priceless.

Regards.

I bought a similar one on Allegro also with a safety valve.
