Regular maintenance is crucial for any vehicle, but it’s especially important for a high-performance truck like the F-150 Limited. Adhering to a strict maintenance schedule will help preserve its longevity, performance, and resale value.
Routine Fluid Checks and Changes
The lifeblood of your engine and transmission lies in its fluids. Regularly checking and changing these is paramount.
- Engine Oil: The 3.5L EcoBoost engine typically requires synthetic blend or full synthetic 5W-30 oil. Ford recommends changing the oil every 5,000-10,000 miles, depending on driving conditions. Always use a high-quality oil filter, such as a Motorcraft FL-500S.
- Transmission Fluid: The 10-speed automatic transmission uses Mercon ULV fluid. While Ford often calls it “lifetime” fluid, many experts recommend a fluid and filter change around 60,000-80,000 miles, especially if you tow frequently. This can prevent costly transmission issues down the line.
- Coolant: Check your engine coolant level regularly. The 3.5L EcoBoost runs hot, and proper cooling is vital. Use Ford-approved Motorcraft Orange coolant (VC-3-B). Flush and replace it every 100,000 miles or five years.
- Brake Fluid: Brake fluid should be checked for color and level. Dark, contaminated fluid should be flushed and replaced, typically every two years, to maintain braking performance and prevent corrosion in the brake system.
Never mix different types of fluids. Always refer to your owner’s manual for specific fluid types and capacities.
Tire Care and Suspension Inspection
Your tires and suspension are critical for safety, ride comfort, and handling. Regular inspection can prevent serious problems.
Tire Maintenance:
- Pressure: Check tire pressure weekly, especially before long trips or towing. Correct pressure (found on your door jamb sticker) improves fuel economy and extends tire life.
- Rotation: Rotate your tires every 5,000-7,500 miles to ensure even wear. This is a simple DIY task with the right tools, like a good floor jack and jack stands.
- Tread Depth: Inspect tread depth using a penny. If Lincoln’s head is fully visible, it’s time for new tires. Uneven wear can indicate alignment or suspension issues.
Suspension Health:
- Inspect shocks, struts, and bushings for leaks or wear every oil change. The F-150 Limited often comes with advanced suspension components that contribute to its smooth ride.
- Listen for unusual noises like clunks or squeaks over bumps, which could signal worn suspension components.
- If you notice uneven tire wear or a spongy ride, have your alignment and suspension components professionally inspected.
Tackling Common EcoBoost Concerns
While powerful, the 3.5L EcoBoost engine has a few known quirks that proactive maintenance can mitigate.
Carbon Buildup: Direct injection engines can suffer from carbon buildup on intake valves. Using top-tier gasoline and occasional intake valve cleaning (either via specialized fuel additives designed for direct injection or a professional walnut blasting service) can help. Spark Plugs and Coil Packs: Ford recommends spark plug replacement every 60,000-100,000 miles. Many EcoBoost owners find better performance and prevent misfires by changing them closer to 50,000 miles, especially if tuned or driven hard. Always use OEM Motorcraft plugs (SP-580 or equivalent) and ensure they are properly gapped.
Timing Chain and Cam Phasers: Some 2018 F-150s, including the Limited, can develop issues with timing chain stretch or cam phaser noise (a “diesel-like” rattle on cold start). Regular oil changes with high-quality oil are your best defense. If you hear persistent noise, consult a Ford specialist.
Upgrading Your 2018 Ford F-150 Limited: Performance and Off-Road Mods
Even a premium truck like the 2018 Ford F-150 Limited can be enhanced to better suit your specific needs, whether that’s boosting power, improving ride quality, or preparing for light off-road excursions.
