Why does diesel fuel smell so good?

Benzene is added to the gasoline to increase octane levels, which improves engine performance and fuel efficiency. Benzene has a naturally sweet smell that most noses are particularly sensitive to. It's so pungent that the human nose can detect it if there's just 1 part per million in the air that we breathe.

Will 1 gallon of gas hurt a diesel engine?

As little as 1% gasoline contamination will lower the diesel flash point by 18 degrees C. This means the diesel fuel will prematurely ignite in the diesel engine, which can lead to engine damage. Gasoline contamination can also damage the fuel pump and mess up diesel injectors.

Why is diesel not flammable?

Diesel fuel can catch fire and is classified as a flammable liquid according to OSHA, because it has a flashpoint above 199.4 degrees Fahrenheit. The flashpoint of diesel is approximately 140 degrees Fahrenheit (60 Celsius). This means in most ambient temperatures it will not ignite.

Is diesel exhaust worse than gas?

The simple answer is diesel emits slightly more pollutants per gallon than gasoline does.

What octane is jet fuel?

The octane ratings of AVGAS, a gasoline-based fuel, are usually either 91 or 100 (lean mixture) and 96 or 130 (rich mixture). The octane rating of jet fuel is much lower, around 15 – this is much more like automotive diesel and thus much more resistant to detonating due to sparks or compression.

Does diesel float on water?

Diesel and water, much like oil and water, don't mix. When you mix diesel and water, diesel will float on top of the water. Water is a heavier liquid and will settle at the bottom of your fuel tank. The density of the water in your tank is why you must use a siphoning hose capable of reaching the bottom.
