# 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.
