Common diesel oil-related concerns and how AMSOIL products may help

Diesel engines face unique stresses that require specialized lubrication.

Concern Why it matters AMSOIL product How it may help Limitation
Severe-service towing Increases engine heat and load. DP530QT-EA Designed to withstand temperature extremes. Requires proper service intervals.
Turbocharger protection High heat can cause oil oxidation. DP530QT-EA Retains viscosity for added protection. Not a repair for mechanical failure.
Engine Wear Soot and friction can damage components. WL7490-EA Helps reduce engine wear. Must be changed at correct intervals.

Common maintenance concerns for this vehicle

Based on available research, owners of the 2018 F-150 should consider the following:

  • Fuel System Integrity: Diesel engines require high attention to fuel filtration and system integrity.
  • Exhaust Aftertreatment: Monitoring the Diesel Particulate Filter (DPF) is a critical part of diesel maintenance.
  • Thermal Management: Managing the unique thermal demands of a turbocharged diesel cycle through correct oil viscosity selection.

Recall, TSB, and manufacturer communication notes

NHTSA research indicates several recalls for the 2018 Ford F-150:

  • Headlight Recall (Campaign 20V097000): Certain high series LED headlamps may have Daytime Running Lamps (DRL) that fail to dim, potentially reducing visibility.
  • Tailgate Latch Recall (Campaign 21V983000): Tailgate latches may unlatch unexpectedly while driving.
  • Tire Recall (Campaign 21V155000): Certain vehicles equipped with Continental tires may have over-cured tires that could develop sidewall breaks or belt separation.
  • Disclaimer: Always verify open recalls by checking your specific VIN through official Ford channels or the NHTSA website.

    About this vehicle

    The 2018 Ford F-150 is a part of the thirteenth generation of the Ford F-Series, which has been a cornerstone of the Ford lineup since 1948. Positioned between the mid-size Ranger and the heavy-duty Super Duty series, the F-150 is designed for applications ranging from personal transportation to light commercial work.

    This specific model features a 3.0L 6-cylinder diesel engine (Engine Code [1]), representing a specialized powertrain option within the broader F-Series ecosystem. Diesel engines in this platform are typically utilized by owners seeking increased torque for towing or improved fuel efficiency for long-distance hauling compared to standard gasoline variants. Maintenance for these diesel models often requires specialized attention to fuel filtration, exhaust aftertreatment systems, and specific oil viscosity requirements to manage the unique thermal and pressure demands of a turbocharged diesel cycle.

    Owners should focus their research on diesel-specific maintenance intervals. It is highly recommended that owners cross-reference all fluid capacities and filter part numbers with a dedicated service guide for the 3.0L variant to ensure compatibility.
