Diesel fuel is a versatile compound with low flammability. Though it’s sold at most gas stations these days, it remains widely misunderstood. Here are some common questions about the fuel source.

What You Should Know About Diesel Fuel

How is it different from gasoline?

While both are derived from crude oil, they're refined differently, creating two distinct substances. Diesel fuel is refined less than gasoline and ends up being thicker and oilier, which is why it delivers more power to an engine and increases the miles per gallon rating. Its boiling point is also higher.

Why is it more expensive than gasoline?

Federal and sometimes state taxes are higher for diesel. Also, the cost of refining it has been driven up by cleaner standards, and most refineries are optimized for gasoline. As the demand for diesel has increased over the years — largely due to economic growth spurring the trucking business — the cost has risen as well.

Though diesel is more expensive per gallon to purchase, it's more energy-efficient. The ability to travel a greater distance per gallon outweighs the higher price. However, many people are unaware of this offset in the cost.

What is ultra-low sulfur diesel?

This term is used if the diesel contains fewer than 15 parts per million of the sulfur present in the fuel. The United States Environmental Protection Agency has imposed standards on sulfuric levels in diesel fuel since they're directly proportional to the level of pollution emitted. It can cause damage to the ozone, plants, water, and the health of both humans and animals. The stricter requirements have made diesel as clean-burning as gasoline.

How long can diesel be safely stored?

Depending on the storage container and the temperature at which it's kept, diesel can generally be stored for up to six months. Higher temperatures will speed up the process of it breaking down, so keeping it in a temperature-controlled area is vital. Water and rust will also accelerate its decomposition.
