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.

AIR BAGS:FRONTAL
Campaign #16V247000 · 26/04/2016
Issue: Ford Motor Company (Ford) is recalling certain model year 2009-2012 Ford Flex, 2008 and 2010-2012 Ford Taurus, 2008-2009 Ford Taurus X, 2008 Mercury Sable, 2009 and 2011 Lincoln MKS vehicles. The driver frontal air bag may improperly inflate during second-stage deployment in the event of a high speed crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Risk: An improperly inflated air bag increases the risk of injury in the event of a crash.
Fix: Ford will notify owners, and dealers will inspect and replace the driver's frontal air bag module, as necessary, free of charge. The recall is expected to begin on June 13, 2016. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 16C06.

STEERING:ELECTRIC POWER ASSIST SYSTEM
Campaign #15V340000 · 02/06/2015
Issue: Ford Motor Company (Ford) is recalling certain model year 2011-2012 Ford Fusion vehicles without a 3.5L engine and Lincoln MKZ hybrid electric vehicles, 2011 Mercury Milan vehicles, 2011-2012 Ford Taurus, Ford Flex, Lincoln MKS, and Lincoln MKT vehicles equipped with a 3.5L GTDI engine and 2013 Ford Taurus, Ford Flex, Lincoln MKS, and Lincoln MKT vehicles equipped with any available engine. The affected vehicles have electric power steering assist systems that may shut down as a result of a steering motor sensor fault.
Risk: If the vehicle experiences a loss of power steering assist, extra steering effort will be required at lower speeds, increasing the risk of a vehicle crash.
Fix: Ford will notify owners, and dealers will check the Power Steering Control Module (PSCM) for Diagnostic Trouble Codes (DTC). If dealers find any loss of steering assist DTCs, the steering gear will be replaced, free of charge. If, no codes are found during the PSCM inspection, the PSCM software will be updated, free of charge. The recall began on July 21, 2015. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 15S18.
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.
