Article 98-20-5 is being republished in its entirety as part of a consolidated 7.3L diagnostic aid booklet.
Some 7.3L DIT engines exhibit rough idle and engine miss due to injector bore scuffing at green engine break-in. This may be due to insufficient lubricity additive in some fuels.
For injectors serviced in the field, one bottle (12 ounce) of Diesel Fuel Lubricity Additive (F8AZ-9C077-AA) must be added to the engine fuel tank at the time of injector replacement. The additive has been shown to be effective in preventing premature wear during the injector break-in period.
