Why isn’t my tank filed to 100 percent capacity?

Your propane is delivered and stored in liquid form. Propane liquid, for example, will expand (become a gas) nearly 17 times as much as water over the same temperature increase. As a result, tanks and cylinders are never completely filled with propane liquid. Tanks are filled to about 80 to 85 percent of their capacity. This leaves a space above the liquid, which allows the propane liquid to expand freely due to changes in temperature.
There are several important characteristics that you need to understand about propane stored in containers. First, heat is added to propane in a tank or cylinder by transfer directly from the air surrounding the container. Hot days, cool nights, rain and snow are a few of the many factors that affect the temperature of the liquid. Because of these temperature changes, you may see fluctuations in your container gauge.

Is propane an environmentally friendly fuel?

Propane, one of the cleanest burning fuels available, is the clear choice for our environment. Propane burns cleaner than gasoline and other fossil fuels. It emits lower levels of carbon dioxide and particulates and doesn’t produce sulfur dioxide, a primary cause of the greenhouse effect. Propane is non-toxic and vaporizes quickly, so it won’t contaminate soil or groundwater.
Propane is also a natural by-product of the gas refining process and in plentiful supply - there’s enough propane to meet America’s needs in the 21st century. Most of the propane used in the United States is produced right here. All these factors make propane one of the most versatile fuels you can find.

How do I read the gauge on my propane tank?

Not all tanks have gauges. If your tank does have a gauge, it is located on the top of the tank, usually under a liftable hood. (Note: Please be careful when you lift the hood as insects sometimes nest there.) For your convenience and comfort, please call your Casey Propane at 438-6500 if your gauge reading measures 20 percent or less. If you don’t have a gauge on your tank, or if you have questions, please call us at 438-6500.
