Bulletin Summary
Some 2017-2022 F-Super-Duty vehicles equipped with a 6.7L diesel engine may exhibit a hard start, lack of power and/or runs rough concern with an illuminated malfunction indicator light (MIL) and diagnostic trouble codes (DTCs) P0087 and/or P008A. This may be due to low fuel level or fuel gelling in cold ambient temperatures.

About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
