Quick answer

Some 2018-2020 F-150 vehicles equipped with a 5.0L engine may exhibit excessive oil consumption of greater than 1L (1 quart) in 4,800 km (3,000 mi) with no visible oil leaks. This may be due to high intake manifold vacuum during some deceleration fuel shut off (DFSO) events resulting in oil being pulled into the combustion chamber from the crankcase, valve guides, and positive crankcase ventilation (PCV). To correct the condition, follow the Service Procedure steps to reprogram the powertrain control module (PCM), install a new engine oil level indicator and change the engine oil and oil filter. The revised PCM calibration reduces engine vacuum during some DFSO events.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
