The 1998 Ford V8 Triton engine in your Club Wagon likely calls for
conventional or synthetic 5W-20 motor oil. However, you
must check your owner's manual for the *exact* specification recommended by Ford. The manual will specify the weight and type of oil (conventional, synthetic blend, or full synthetic) best suited for your vehicle's engine and operating conditions.
Ignoring the owner's manual recommendation could damage your engine. The recommended oil weight and type are crucial for proper lubrication and engine longevity.
