Diesel fuel additive is important for EGR engines it raises the Cenate number for cleaner burning, I used the Power Service since it was the only one Cummins endorsed it has the Cummins logo on the bottle. If what ever brand has Cenate booster it should help for non EGR engines I would think, diesel today with the 5 to 30% BIO is real crappy fuel ,It doesn't come even close to meeting the fuel specs for a older diesel engine .Some stations offer 100% diesel fuel but it has a premium price
