- Drain Plug Torque: 32 ft/lbs.
OEM Specification Note: The AMSOIL lookup note references Ford Material Engineering Specification WSS-M2C171-F1. It notes that Ford recommends this specification over CK-4 for older diesel engines like the 6.0L to provide additional wear protection.
Automatic Transmission Fluid (ATF) Specifications
The transmission requirements depend on your specific configuration (4R75W vs 5R110W).
4R75W Transmission
- Total Fill Capacity: 13.9 quarts
- Initial Fill: 5 quarts
5R110W Transmission
- Total Fill Capacity: 19 quarts
- Initial Fill: 7.4 quarts
- Important Note: Per Ford Special Service Message 21114, Torqshift automatic transmissions (including 2004-2008 E-series) should be serviced with Mercon LV fluid instead of Mercon SP. Mixing Mercon LV and Mercon SP is acceptable.

About this vehicle
The 2004 Ford E350 is part of the Ford E-Series family, also known as the Econoline or Club Wagon. This series has long been a staple in both retail and commercial markets, often utilized as cargo vans, passenger vans, or cutaway/stripped-chassis platforms for specialized work.
This specific configuration features the 6.0L Power Stroke diesel engine, which is a critical component for heavy-duty applications. The inclusion of a turbocharger suggests this vehicle was intended for high-torque requirements, such as towing or heavy hauling. Because it is a diesel-powered vehicle, maintenance requirements differ significantly from the gasoline-powered Modular engines found in other Ford models. Owners should distinguish between these engine families to ensure correct part selection and fluid compatibility.
Maintenance context for this vehicle emphasizes specialized oil services and fuel filtration due to the demanding nature of diesel work. While many E-Series models share a chassis, the 6.0L Power Stroke requires specific attention to lubrication and cooling systems to support its heavy-duty performance capabilities.
Common questions about this vehicle’s diesel oil and maintenance
How much oil does my 2004 Ford E350 6.0L take?
It takes 15 quarts of oil when replacing the filter.
What is the preferred oil viscosity for my diesel engine?
For temperatures above -1°C (31°F), 15W-40 is the preferred viscosity. If operating between -20°C and -1°C, 10W-30 is preferred.
Can I use CK-4 oil in my 6.0L Power Stroke?
The AMSOIL lookup note states that Ford continues to recommend oils meeting WSS-M2C171-F1 for older diesel engines like the 6.0L, noting that some CK-4 formulations may show inadequate wear protection compared to earlier formulations.
What transmission fluid should I use for my Torqshift transmission?
Per Ford Special Service Message 21114, you should use Mercon LV fluid. The AMSOIL lookup lists Signature Series Multi-Vehicle (ATFPK-EA) for this application.
How often should I change my coolant?
AMSOIL products like Antifreeze & Coolant (ANTPC1G-EA) provide protection for up to 150,000 miles or 5 years, but you should consult your owner’s manual for specific intervals.
What torque spec is needed for the oil drain plug?
The oil drain plug should be torqued to 32 ft/lbs.
