A robust and well-maintained truck like your 2015 Ford F-250 Super Duty is a vital asset, whether for work or recreation. Adhering to the factory maintenance schedule is the best way to ensure its longevity, reliability, and optimal performance. This guide outlines the key service intervals for your gas (6.2L V8) or diesel (6.7L Power Stroke V8) F-250, helping you keep it running strong for years to come.

Normal Operating Conditions Maintenance

Every 5,000 - 10,000 Miles (or 6-12 Months): Oil Change and Tire Rotation

• Oil and Filter Change: For vehicles operating under normal conditions, Ford recommends an oil and filter change every 10,000 miles or 12 months, whichever comes first, using a synthetic blend motor oil meeting Ford specification WSS-M2C945-A (for 6.2L gasoline) or WSS-M2C171-F1 (for 6.7L diesel). However, many technicians and owners opt for a 5,000-7,500 mile interval, especially for diesel engines, as a more conservative approach. The 6.7L Power Stroke diesel holds a substantial amount of oil (13 quarts), making timely changes critical.
• Tire Rotation: Rotating your tires at every oil change helps promote even wear and extends tire life. Inspect tire pressure and condition.

Every 10,000 Miles / 12 Months:

• Repeat Oil and Filter Change, Tire Rotation.
• Inspect all fluid levels and top off as needed (brake fluid, power steering fluid, windshield washer fluid).
• Visually inspect the exhaust system, steering linkage, ball joints, suspension components, drive shafts, and u-joints.

Every 20,000 Miles / 24 Months:

• Repeat 10,000-mile services.
• Cabin Air Filter Replacement: Recommended for improved climate control performance and interior air quality.
• Engine Air Filter (Diesel): For the 6.7L Power Stroke, the engine air filter often requires replacement around this interval, or sooner if operating in dusty conditions. Always inspect at every oil change.

Every 30,000 Miles / 36 Months:

• Repeat 10,000-mile services.
• Fuel Filter Replacement (Diesel): The 6.7L Power Stroke diesel has primary and secondary fuel filters that are critical for protecting the sophisticated high-pressure fuel system. Replacement at this interval, or even more frequently in areas with questionable fuel quality, is highly recommended.
• Brake Fluid Flush: Brake fluid absorbs moisture over time, reducing its effectiveness and potentially leading to corrosion in the braking system. A fluid flush every three years or 30,000 miles helps maintain braking performance and system integrity.

Every 60,000 Miles / 72 Months:

• Repeat 10,000-mile services.
• Cabin Air Filter Replacement: (If not replaced at 20k or 40k).
• Engine Air Filter (Gasoline): For the 6.2L gasoline engine, the air filter typically lasts longer than the diesel's, often recommended for replacement around 45,000-60,000 miles.
• Differential Fluid Change (Front & Rear): Especially important for 4x4 models and trucks that tow. Fresh gear oil ensures proper lubrication and cooling for these hardworking components.
• Transfer Case Fluid Change: Critical for 4x4 models to ensure smooth operation and prevent wear.
• Accessory Drive Belt Inspection: Inspect for cracks, fraying, or glazing. While replacement isn't always specified until 100,000 miles, an inspection at 60,000 miles allows for proactive replacement if wear is evident.

Every 90,000 Miles / 108 Months:

• Repeat 10,000-mile services.
• Fuel Filter Replacement (Diesel): Repeat of the 30,000-mile interval.
• Spark Plug Replacement (Gasoline): For the 6.2L V8, spark plugs are generally recommended for replacement around 90,000-100,000 miles. Using original equipment (OE) iridium-tipped plugs is crucial for proper performance.

Every 100,000 Miles / 120 Months:

• Repeat 10,000-mile services.
• Coolant Flush: The engine coolant should be flushed and replaced with fresh Ford-specified coolant (Motorcraft Yellow Prediluted Antifreeze/Coolant for the 6.7L Power Stroke) to maintain proper engine cooling and prevent corrosion.
• Transmission Fluid Service: This is a critical service, especially for trucks that tow or haul regularly. Ford typically recommends inspecting the transmission fluid level and condition, and often advises a fluid and filter change at this interval, or sooner depending on usage. Refer to your owner's manual for specific severe-duty intervals.
• Timing Chain Inspection: The 6.2L gasoline and 6.7L diesel engines both use timing chains, which are designed to last the life of the engine under normal circumstances and do not have a scheduled replacement interval. However, an inspection for excessive stretch or noise at this mileage is prudent.
• Accessory Drive Belt Replacement: If not replaced earlier due to wear, it's good preventative maintenance to replace the accessory drive belt (serpentine belt) at this interval to avoid unexpected breakdowns.

Every 150,000 Miles / 180 Months:

• Repeat 10,000-mile services.
• Fuel Filter Replacement (Diesel): Repeat of the 30,000-mile interval.
• Differential Fluid Change (Front & Rear): Repeat of the 60,000-mile interval.
• Transfer Case Fluid Change: Repeat of the 60,000-mile interval.
• Coolant Flush: Repeat of the 100,000-mile interval.
• PCV Valve Replacement (Gasoline): The Positive Crankcase Ventilation (PCV) valve can sometimes last longer, but replacing it at this mileage can prevent potential issues related to oil consumption or engine performance.

Severe-duty schedule

Your F-250 is a Super Duty truck, likely to be used for more than just grocery runs. Ford defines "severe duty" conditions as:

• Towing or hauling heavy loads frequently.
• Extensive idling or stop-and-go driving.
• Operating in dusty, sandy, or muddy conditions.
• Operating in extremely cold climates.
• Frequent short trips (less than 10 miles).

If your truck falls into any of these categories, you should consider more frequent maintenance:

• Oil and Filter Change: Every 5,000 miles or 6 months.
• Engine Air Filter: Inspect and replace more frequently, potentially every 10,000-15,000 miles in very dusty conditions.
• Fuel Filter (Diesel): Every 15,000 miles or 12 months, or even sooner with questionable fuel.
• Differential and Transfer Case Service: Every 30,000 miles.
• Transmission Fluid Service: Every 30,000-60,000 miles, especially if towing heavy loads frequently.
• Accessory Drive Belt: Inspect more frequently and replace as soon as any signs of wear appear.

Known issues by mileage (6.7L Power Stroke and 6.2L V8)

20,000 - 60,000 miles:

• 6.7L Power Stroke - Diesel Exhaust Fluid (DEF) System Issues: Sensor failures, crystallization in the DEF tank, or heater issues can trigger "reduced speed" warnings. More common on earlier models but still seen.
• 6.7L Power Stroke - Turbocharger issues: Actuator problems or bearing wear can occur, sometimes signaled by a whining noise or reduced boost.
• 6.2L V8 - Spark Plug Ejection (less common on later models): While largely resolved from earlier Triton engines, some instances of spark plug thread issues have been reported. Proper torque is critical during replacement.

60,000 - 100,000 miles:

• 6.7L Power Stroke - High-Pressure Fuel Pump (HPFP) Failure: This is a significant concern for the 6.7L Power Stroke. Contamination or wear in the HPFP can send metal debris throughout the fuel system, requiring very expensive repairs. The fuel filters are your first line of defense; timely changes are paramount. Quality fuel and additives are also recommended.
• 6.7L Power Stroke - Injector Issues: Sticking or failing fuel injectors can cause rough idling, misfires, or reduced performance.
• Both Engines - EPAS (Electric Power Assist Steering) Failures: While not extremely common, issues with the EPAS system can lead to loss of power steering or unusual noises.
• Both Engines - Suspension Components: Wear on ball joints, tie rods, and shock absorbers is typical for heavy-duty trucks, especially those used for hauling or off-roading.

100,000+ miles:

• 6.7L Power Stroke - EGR Cooler/Valve Issues: Clogging or failure of the Exhaust Gas Recirculation (EGR) system components can lead to reduced performance and check engine lights.
• Both Engines - Transmission issues: Torque converter shudder, delayed shifts, or slipping can become more prevalent, especially if transmission fluid changes have been neglected.
• Both Engines - Rust: Frame and body rust can start to become a more significant issue, especially in regions that use road salt.

What you can DIY vs shop

Many maintenance items on your F-250 can be handled by aDIYer with basic mechanical skills and tools, potentially saving you a significant amount on labor costs.

Good for DIY:

• Oil and Filter Change: Requires a large oil drain pan (especially for diesel), a filter wrench, and proper disposal of used oil. This is one of the most common DIY tasks.
• Tire Rotation: Requires a jack, jack stands, and a lug wrench. Torque wrench recommended for proper lug nut tightening.
• Cabin Air Filter Replacement: Usually a simple R&R (remove and replace) behind the glove box.
• Engine Air Filter Replacement: Typically involves unlatching clips on the airbox.
• Fuel Filter Replacement (Diesel): Slightly more involved than gas engines, but still very doable for the mechanically inclined. Requires careful attention to bleeding the system afterward.
• PCV Valve Replacement (Gasoline): Generally an easy component to swap out.

Better for a Shop:

• Brake Fluid Flush: While possible to DIY, proper bleeding procedures and specialized tools (like a pressure bleeder) make it more efficient and safer for a shop.
• Coolant Flush: Draining and refilling the system properly to avoid air pockets can be tricky. Disposal of old coolant is also a consideration.
• Transmission Fluid Service: Requires specific fluid, often specialized filling equipment, and knowledge of proper level checking procedures (which can be complex on some automatic transmissions).
• Differential and Transfer Case Service: Involves getting under the truck, often removing covers, and dealing with messy gear oil. Proper sealant application is also crucial.
• Spark Plug Replacement (Gasoline): Can be labor-intensive, especially on V8s where some plugs are difficult to access. Incorrect torque can lead to serious issues.
• Timing Chain Inspection/Replacement: Definitely a job for experienced technicians due to the complexity and potential for catastrophic engine damage if done incorrectly.
• Any Diagnostic Work: If you have a check engine light or performance issue, a qualified technician has the specialized diagnostic tools and training to accurately identify and fix the problem.

Always ensure you use the correct fluids and parts meeting Ford's specifications to maintain your warranty and ensure optimal performance. Refer to your owner's manual for the most accurate and detailed maintenance information specific to your truck.
