Here is a look at exactly what that means.

What is cetane?

Before breaking down the different grades of diesel fuel, it’s important to have an understanding of cetane and cetane ratings.

Cetane is a highly flammable chemical that is a natural part of diesel fuel. Since it ignites easily, it is used by the diesel fuel industry to help determine fuel combustion quality.

Each grade of diesel fuel is given a cetane number. A high cetane number indicates a fast rate of ignition. When it comes to vehicles that rely on diesel fuel, this means that the higher the cetane number the better. A high cetane number also clues you into how easily a commercial vehicle is able to execute a cold start. A cetane rating is also indicative of a diesel fuel’s ignition quality.
