OEM Specification Notes
The AMSOIL lookup note references Ford Material Engineering Specification WSS-M2C171-F1 for this application. Note that in 2016, Ford superseded the original recommendation of WSS-M2C171-D with WSS-M2C171-F1. Ford continues to recommend oils meeting WSS-M2C171-F1 instead of CK-4 motor oils for older diesel engines like the 6.0L, as testing on some CK-4 formulations has shown inadequate wear protection compared to CJ-4 formulations.
Automatic Transmission Fluid (ATF) Details
For vehicles equipped with the 4R100 transmission, maintenance is critical for heavy-duty performance.
| Specification | Capacity/Details |
|---|---|
| Transmission Model | 4R100 |
| Update Note | Updated from Mercon to Mercon V per TSB 06-14-4 |
| 4 Speed 26 Plate OAC Total Fill | 17.6 quarts |

Diesel maintenance notes for this vehicle
Maintaining a 6.0L Power Stroke requires attention to several key areas to ensure longevity:
- Filtration: Use high-efficiency filters like the AMSOIL SDF88, which is designed specifically for Ford 6.0/6.4L diesel engines and replaces Ford FL2016, Donaldson P550528, and WIX 57312.
- Cooling System: Maintain the cooling system to prevent issues common in high-stress diesel environments. The AMSOIL lookup lists ANTPC1G-EA and ANT1G-EA as compatible options.
- Air Intake: Ensure the air filter is clean to prevent restriction; PowerCore® filters are noted for lower initial restriction which protects engine performance and fuel economy.
Common diesel oil-related concerns and how AMSOIL products may help
| Concern | Why it matters | AMSOIL product from this lookup | How it may help | Important limitation |
|---|---|---|---|---|
| Engine Wear | High-stress diesel operation causes metal-on-metal contact. | DMEQT-EA | Delivers up to 6X more wear protection. | Requires regular service intervals. |
| Extreme Temperatures | Viscosity changes can affect lubrication during starts or heavy loads. | ADPQT-EA | Excels in extreme temperatures. | Must match viscosity to ambient temperature. |
| Soot & Contaminants | Diesel engines produce soot that can degrade oil quality. | EA15K88-EA | Provides 99% efficiency at 20 microns. | Filter must be changed per service schedule. |
Common maintenance concerns for this vehicle
Based on NHTSA consumer reports and research, owners of the 2004 Ford Excursion should monitor several areas:
- Electrical & Fuel Systems: Some owners have reported engine stalling or loss of power.
- Fuel System Integrity: Maintenance of fuel filters and injectors is vital for the Power Stroke diesel family.
- Cooling System: Given the high-stress environment, monitoring cooling system health is a priority for longevity.
Recall, TSB, and manufacturer communication notes
Official NHTSA research indicates two notable recalls/campaigns for this vehicle model year:
- Electrical System (Campaign 05V270000): Certain 6.0L diesel engines may experience stalling without warning. The remedy involves upgrading or replacing the Fuel Injection Control Module (FICM) wire harness or the Injection Control Pressure (ICP) sensor connector.
- Exterior Lighting (Campaign 11V352000): A recall regarding multi-function switches that may malfunction, affecting turn signals, tail lights, hazard flashers, or brake lights.
Note: Always verify open recalls by checking your specific VIN through the Ford Customer Relationship Center or an authorized dealer.
About this vehicle
The 2004 Ford Excursion is a heavy-duty, full-size SUV built on the Ford F-250 Super Duty chassis. It is recognized as one of the longest-wheelbase SUVs ever mass-produced, designed to offer significant interior volume and towing capabilities that exceed standard consumer-oriented SUVs. Because it shares architecture with the Super Duty line, it was engineered for heavy-duty use rather than light-duty passenger transport.
At its core is the Ford Power Stroke diesel engine family. The 6.0L variant used in this vehicle was a key member of this lineage, utilized across various Ford platforms including the F-Series Super Duty and the Excursion itself. These engines were designed for high-stress environments, making diligent maintenance—specifically regarding fuel system integrity, turbocharger health, and cooling system maintenance—critical for long-term ownership. Owners often focus on heavy-duty performance, but given the complexity of the 6.0L diesel powertrain, regular fluid changes and filtration are essential to prevent common diesel-related issues.
Common questions about this vehicle’s diesel oil and maintenance
How much oil does my 2004 Excursion 6.0L take?
It takes 15 quarts of engine oil when performing a change with the filter.
What is the preferred oil viscosity for my diesel Excursion?
The AMSOIL lookup suggests 15W-40 is preferred if operating temperatures are above -1°C (31°F). For colder climates, 10W-30 is preferred between -20°C and -1°C.
Can I use CK-4 oil in my 2004 Excursion?
The AMSOIL lookup note states that Ford recommends meeting the WSS-M2C171-F1 specification for older diesel engines like the 6.0L, noting that some CK-4 formulations may have inadequate wear protection compared to earlier CJ-4 formulations.
What oil filter is designed specifically for my engine?
The AMSOIL SDF88 oil filter is designed specifically for Ford 6.0/6.4L diesel engines and replaces several OEM and other aftermarket part numbers.
How do I prevent engine stalling related to electrical issues?
While AMSOIL products support engine health through lubrication, NHTSA recall 05V270000 suggests that stalling in some 6.0L models may be related to the FICM wire harness or ICP sensor connector; owners should check for this specific recall.
What is the torque spec for my oil drain plug?
The confirmed torque specification for the oil drain plug is 32 ft/lbs.
