The 2019 Ford Super Duty belongs to the 4th generation (2017-2019 powertrain) (2017-2019), built with 6.2L Boss V8 gas, or the 2nd-generation 6.7L Power Stroke V8 diesel - both on the 6R140 6-speed TorqShift automatic. It takes 5W-30 full synthetic blend (6.2L, WSS-M2C946-B1); Motorcraft Super Duty Diesel Motor Oil, 10W-30 normal/5W-40 severe (6.7L Power Stroke). Oil changes run 7,500-10,000 miles per the oil life monitor (gas); 10,000 miles or oil life monitor signal, normal duty (diesel). This is the final model year of that generation, usually the most sorted version of the design before the redesign that followed.
A 2019 Ford Super Duty is 7 years old in 2026, which at an average 12,000 miles a year puts it around 84,000 miles - the interval that decides its future. At roughly 84,000 miles the bigger fluids come due - transmission, differential, coolant - and this is the window that separates vehicles that reach 200,000 miles from those that do not. Deferring here is what produces expensive failures later. On that mileage estimate it should already have had transmission or CVT fluid, differential fluid and brake fluid at 60,000 miles, and the next milestone is 90,000 miles - a second transmission service, suspension inspection and belts - roughly 1 years away at average use.
The fault most worth knowing about on this generation is Bosch CP4.2 high-pressure fuel pump contamination sensitivity on the 6.7L Power Stroke - a failure can contaminate the entire fuel system. Owners also report EGR cooler fouling and failure over time, a longstanding Power Stroke-family risk; and 6.2L Boss V8 uses a dual-plug-per-cylinder head (16 spark plugs total) - the secondary set on the side of each head is commonly neglected. None of these are certainties on any individual vehicle - they are the patterns worth checking for when you buy or when a symptom appears.

| Interval | Service |
|---|---|
| Every 7,500 mi (or IOLM signal; gas V8) | Oil & filter change - grade and capacity per your engine (see oil type/capacity above), Tire rotation, Inspect brakes, belts, hoses, and driveline U-joints, Check all fluid levels |
| Every 10,000 mi (or IOLM signal; 6.7L Power Stroke diesel, normal duty) | Oil & filter change - Motorcraft diesel-spec oil (see oil type/capacity above), Tire rotation, Inspect brakes, belts, hoses, and driveline U-joints, Drain water from the fuel/water separator |
| Every 5,000 mi (severe duty: towing, trailer, extensive idling, off-road, dusty conditions - all engines) | Oil & filter change on the shortened interval - do not stretch past this while towing or plowing regularly, Tire rotation, Inspect brake pads (towing accelerates wear) |
| Every 20,000 mi | Replace cabin air filter, Inspect brake pads & rotors, Inspect front suspension bushings and ball joints - a heavier front end than a half-ton truck |
| Every 22,500 mi (6.7L Power Stroke diesel - fuel filters, normal duty) | Replace both fuel filters (chassis-mounted fuel/water separator and engine-mounted secondary) - 6.7L Power Stroke |
| Every 15,000 mi (6.7L Power Stroke diesel, severe duty or B20 biodiesel blends, or every 6 months whichever comes first) | Replace both fuel filters on the shortened interval - 6.7L Power Stroke |
| Every 30,000 mi | Inspect/replace engine air filter (gas engines), Inspect drive belt condition, Inspect coolant condition and hoses |
| Every 36 months (brake fluid) | Replace brake fluid - Motorcraft DOT 3 LV or DOT 4 LV |
| Every 45,000 mi (6.7L Power Stroke diesel) | Replace the CCV (crankcase ventilation) oil separator - 6.7L Power Stroke, Inspect turbocharger boost hoses and clamps - 6.7L Power Stroke, Coolant flush and refill on the recurring interval for the 6.7L Power Stroke (the first flush lands at a longer mileage under normal duty - see coolant field above; severe-duty trucks are on this interval from the start) |
| Every 60,000 mi (severe duty: towing/trailering/plowing - transmission, transfer case, differentials) | Automatic transmission fluid service - Mercon LV (6R140 six-speed) or Mercon ULV (10R140 ten-speed); the two are not interchangeable, Transfer case fluid change (4x4), Front and rear differential fluid change |
| Every 100,000 mi (6.2L V8 - 16 spark plugs) | Replace all 16 spark plugs (2 per cylinder) - the second plug on the side of each head is easy to miss |
| Every 100,000 mi | Rear differential fluid change (normal duty), Inspect water pump and serpentine belt |
| Every 105,000 mi (6.7L Power Stroke diesel - first coolant service, normal duty) | First coolant flush and refill for the 6.7L Power Stroke - Motorcraft coolant (see coolant field above); much sooner under severe duty (see the 45,000 mi severe-duty row) |
| Every 150,000 mi | Automatic transmission fluid service (normal duty), Transfer case fluid change (normal duty, 4x4), Front differential fluid change (normal duty, 4x4) |
| Every 250,000 mi (6.7L Power Stroke diesel - DPF ash service) | Diesel particulate filter (DPF) ash service for the 6.7L Power Stroke - a dealer regeneration/cleaning procedure, not owner-serviceable; a dash service light indicates when it is due |
The table above is indexed by service interval. This is the same schedule indexed by odometer reading, for when you know your mileage and want the list. If your odometer sits between these figures, work back to the last one you passed and catch up anything skipped.

Maintenance keeps these away, but when the dash does light up these are the codes this vehicle throws most often - each with what it means and what the repair actually costs.
