How Ford schedules service: Intelligent Oil-Life Monitor
Ford uses the Intelligent Oil-Life Monitor (IOLM) to determine when oil changes are due based on actual driving load — not just mileage. Ford's published cap is 10,000 miles or 1 year, whichever comes first. The schedule below reflects Ford's Normal service intervals; F-Series trucks and Super Duty have additional towing-specific items.

Campaign #20V795000 · 17/12/2020
Issue: Ford Motor Company (Ford) is recalling certain 2021 E-350 and E-450 vehicles. The underside of the engine cover may have mispositioned insulation, allowing the cover to get excessively hot.
Risk: Direct and continuous contact with certain areas of engine cover surface in the passenger compartment may increase the risk of injury or burns to the skin of the driver or front seat passenger.
Fix: Ford will notify owners, and dealers will inspect the engine cover for gaps between the rubber seal and the insulation. If gaps are present, the dealer will install engine cover insulation patches in the right hand and left hand inner lower corners of the engine cover. The dealer will also update the powertrain calibration for heat management under elevated idle conditions should a vehicle be equipped with SEIC or BCP, free of charge. The recall began February 15, 2021. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 20S73.

SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP
Campaign #20V175000 · 23/03/2020
Issue: Ford Motor Company (Ford) is recalling certain 2021 E-350 and E-450 vehicles. A wire harness in the rear of the vehicle may contact the vehicle frame, resulting in damage to the circuits that support the fuel pump and the anti-lock braking system (ABS).
Risk: Damage to the fuel pump circuit in the wiring harness could result in an unexpected engine stall. Damage to the ABS wiring can lead to reduction of ABS functionality and a loss of roll stability control (RSC) functionality. These scenarios increase the risk of a crash.
Fix: Ford will notify owners, and dealers will inspect the wire harness for damage. If no damage is found, dealers will apply anti-abrasion tape over the area and ensure clearance to surrounding components. If damage is found, dealers will splice in new wire and apply anti-abrasion tape over the area and ensure clearance to surrounding components. All services will be performed free of charge. The recall began May 18, 2020. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 20S13.

Issue: Ford Motor Company (Ford) is recalling certain 2020 F-550 and 2021 E-350 and E-450 vehicles. The rear axle differential fluid may be below the minimum level, possibly resulting in a failure of the rear axle assembly and driveshaft separation.
Risk: If the driveshaft separates, there may be a loss of drive, increasing the risk of crash. Additionally, if the parking brake is not applied, unintended vehicle movement can occur and increase the risk of injury or crash.
Fix: Ford will notify owners, and dealers will inspect the rear axle differential fluid level and adjust it, or replace the rear axle as necessary, free of charge. The recall began March 19, 2020. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 20S09.

Issue: Ford Motor Company (Ford) is recalling certain 2021-2022 E-350 and E-450 vehicles equipped with dual rear wheels. An inadequate connection between the power steering pressure line and the brake Hydroboost unit may result in a sudden loss of power steering fluid.
Risk: A sudden loss of power steering fluid can result in a loss of power steering and power brake assist, increasing the risk of a crash.
Fix: Dealers will inspect the connection between the power steering lines and the Hydroboost unit, and replace the power steering lines, as necessary, free of charge.

Essential maintenance
Critical for safety and preventing major damage
Engine Oil & Filter
Every 7,500 miReplace synthetic-blend or full-synthetic Motorcraft oil per the IOLM, or every 7,500-10,000 miles. EcoBoost engines require full synthetic; Coyote 5.0L V8 specifies SAE 5W-30.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Tire Rotation
Every 10,000 miRotate tires every 10,000 miles, or with every other oil change. F-150 4x4 owners should rotate every 5,000-7,500 miles to even out drivetrain bias wear.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Brake Inspection
Every 10,000 miInspect brake pads, rotors, and brake fluid level every 10,000 miles. Front pads on F-150 and Explorer typically last 40,000-60,000 miles.
Estimated cost — typical U.S. ranges
Dealer

Shop

DIY
Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Brake Fluid
Every 45,000 miFord specifies brake fluid replacement on an inspection basis, but moisture testing every 3 years is recommended. Replace if reading exceeds 3% water content.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140
DIY
~$10–$25
DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Important maintenance
Keeps your vehicle running smoothly and efficiently
Engine Air Filter
Every 30,000 miReplace the engine air filter every 30,000 miles. EcoBoost turbocharged engines are sensitive to airflow restriction — don't extend.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Automatic Transmission Fluid
Every 150,000 miFord 6R80, 10R80, and 8F transmissions use Mercon LV fluid rated 150,000 miles under normal service. Severe service (towing, plowing) drops this to 60,000 miles.
Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
Transfer Case Fluid (4WD models)
Every 60,000 miF-150 4x4 and Bronco 4x4: replace transfer case fluid every 60,000 miles. Use Motorcraft XL-12 — do not substitute generic transfer case fluid.
Estimated cost — typical U.S. ranges
Dealer
~$105–$140
Shop
~$75–$100
DIY
~$15–$40
AWD/4WD vehicles only. Easy drain-and-fill on most platforms.
Rear Differential Fluid
Every 100,000 miF-Series and Expedition: replace rear axle fluid every 100,000 miles, or 50,000 miles if towing. Limited-slip rear ends require friction-modifier additive.
Estimated cost — typical U.S. ranges
Dealer
~$150–$195
Shop
~$105–$135
DIY
~$20–$50
Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.
Spark Plugs
Every 100,000 miIridium spark plugs on Coyote 5.0L, EcoBoost 2.7L/3.5L, and 2.3L are rated 100,000 miles. EcoBoost engines: never exceed the interval — gap erosion causes coil failure.
Estimated cost — typical U.S. ranges
Dealer
~$285–$390
Shop
~$200–$275
DIY
~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
Engine Coolant
Every 50,000 miMotorcraft Orange (Dex-Cool compatible) coolant: first change at 100,000 miles, then every 50,000. Older trucks with Yellow Motorcraft coolant: 50,000 miles throughout.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
Recommended maintenance
Extends the life of your vehicle and improves comfort
Cabin Air Filter
Every 20,000 miReplace the cabin air filter every 20,000 miles. On F-150, located behind the glove box; on Escape and Explorer, accessed from the passenger footwell.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
