How long does a propane tank last?

Typical lifespan
10–12 yr

A steel cylinder of liquefied petroleum gas, filled to about 80% of its water capacity to leave room for vapour expansion.

US cylinders must be requalified 12 years after manufacture, then every 5 or 10 years after that.

How that compares

Propane tank against things of a similar time.

Propane tank 10–12 yr
Car 8–20 yr
Air conditioner 8–20 yr
Leopard 10–21 yr
Jaguar 11–22 yr
Snow leopard 10–21 yr
Labrador retriever 10–14 yr
Mute swan 10–30 yr

What that means over time

Assuming the typical lifespan above and immediate replacement.
Period How many you would buy
Per year 0.0833 replacements
Over 10 years 1 of them
Over a 30-year mortgage 2.5 of them

Lifespans are medians under ordinary use, not guarantees. Maintenance, how hard it is used, and build quality move individual examples a long way in both directions — which is why the range above is as wide as it is.
