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. We do not need any additives that have the anti-gel added to the mix.

No we should not have to buy additives BUT the dry diesel we purchase at the pump is what causes the failures, and the badly designed part being installed for 2019-2020 trucks was definitely the wrong decision by RAM/Cummins. Owning a CP4 3500 equipped RAM dually work truck, I run both products and I don't worry about failures. The Hotshot LX 4 was introduced after the testing and claims to be better.
