In Georgia, the minimum cetane rating at the pump for diesel is supposed to be 40. Does going to 50 or higher cetane justify the cost per gallon per mile? Or, does it make you feel better knowing you put in a higher cetane rated fuel? Those decisions are up to you. Most suggest you obtain a cetane number in the high 40’s if possible. Higher cetane will improve performance, and to a degree mileage. The Ford Superduty 6.7L truck was designed to run on a minimum cetane number of 40. The higher the cetane number, the more efficient the combustion and power. Would 91 or higher octane make it get better fuel mileage? Maybe, but it would surely cut down on pre-ignition and detonation. If you have a car that recommends 87 octane, will it run on lower octane? Sure, but maybe not as efficiently. Cetane numbers are like octane numbers for gas vehicles. If your diesel fuel does not have a high enough cetane number, Ford suggests that a fuel additive may be required.
