How much oil does a 2000 7.3 Excursion take?
Approximately 15 quarts of engine oil are required for a full oil change with a new filter on the 2000 Excursion's 7.3L Power Stroke (roughly 14 quarts if you don't replace the filter). The recommended oil type is diesel-grade oil, typically 15W-40; many owners also use synthetic 5W-40 in cold climates. This article details the capacity, what affects it, and best practices for maintaining the engine.
Oil capacity specifics for the 7.3L Power Stroke
The capacity you need depends on whether you replace the oil filter during the change. The engine's oil pan and lubrication system hold a certain total amount, and replacing the filter adds to the total. The figures below reflect the commonly cited values used by owners and service guides.
- With the oil filter replaced during the change: about 15 quarts (roughly 14.5–15.0 quarts total).
- Without replacing the filter: about 14 quarts.
In practical terms, most full oil changes on a 7.3L include changing the filter, so plan for about 15 quarts of oil. Always verify with your manual or a factory service bulletin if you have a non-standard filter or a modified engine.
Oil type and viscosity recommendations
Choosing the right oil is as important as the quantity. The 7.3L Power Stroke has historically used diesel-grade oils, with 15W-40 being the common default. In colder climates or for extended drain intervals, many owners opt for synthetic 5W-40 diesel oil, which can improve cold start performance and protection.
The following options are commonly used by 7.3L owners, but you should confirm with your owner’s manual or a Ford service bulletin for your exact model year and climate:
- 15W-40 diesel engine oil (conventional) – standard choice for many 7.3L models.
- 5W-40 synthetic diesel engine oil – popular in cold weather or for longer drain intervals.
Regardless of choice, use an oil that meets or exceeds the engine’s required API diesel specifications and the Ford service guidance. If in doubt, consult your manual or a trusted mechanic.
Practical notes for performing an oil change
When servicing the 7.3L, allow the engine to cool, use a clean drain pan, replace the spin-on oil filter with the correct part, and ensure you have the right amount of oil to avoid overfill. Tighten plugs to the recommended torque and check for leaks after starting the engine.
Summary
The 2000 Ford Excursion with the 7.3L Power Stroke typically requires about 15 quarts of engine oil when performing a full oil change with a new filter, and roughly 14 quarts if the filter is not replaced. Standard practice is to use 15W-40 diesel oil, or synthetic 5W-40 in colder climates or for extended drain intervals. Always verify exact capacity and oil specifications in your owner’s manual or a Ford service bulletin, as variations can occur with aftermarket filters or engine modifications. Regular maintenance helps keep the 7.3L running reliably for years.
