Quick Answer: What oil does a 2015 Ford F-350 6.7L Diesel take?
Engine Oil Specifications & Details
Maintaining the correct oil viscosity is critical for the longevity of the 6.7L Power Stroke diesel engine, especially under varying temperature ranges and load conditions.
Oil Viscosity Guide
| Temperature Range | Recommended Viscosity |
|---|---|
| Below 10°C | 0W-30, 0W-40 |
| Above -18°C | 10W-30 |
| Above -7°C | 15W-40 |
| Above -29°C | 5W-40 |
Note: The manufacturer recommends 10W-30 for normal usage and 5W-40 for severe operations. If biodiesel fuel blends (B20 max) are used, the use of 5W-40 or 15W-40 oil is recommended.
Oil Capacity & Torque
| Specification | Value |
|---|---|
| Total Oil Capacity | 13.1 quarts (with filter) |
| Oil Drain Plug Torque | 19 ft/lbs |
Always check the oil level after refilling to ensure accuracy.
Manufacturer Specification Notes
The AMSOIL lookup note references Ford Material Engineering Specification WSS-M2C171-F1 for this application. The note states that in 2016, Ford superseded the original recommendation of WSS-M2C171-D with WSS-M2C171-F1.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 for its 3.2L and 6.7L diesel engines, as testing on some CK-4 formulations showed inadequate wear protection compared to the requirements in the F1 specification.
Diesel maintenance notes for this vehicle
Proper maintenance of a high-torque diesel engine like the 6.7L Power Stroke requires attention to filtration and fluid integrity. Owners should focus on:
- Filtration: Utilizing high-efficiency oil filters to mitigate the effects of soot and combustion byproducts.
- Fluid Management: Adhering to strict oil change intervals to manage soot loading and oxidation.
- Turbocharger Health: Ensuring consistent lubrication to protect turbo components during high-stress operation.
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 |
|---|---|---|---|---|
| Soot & Combustion Byproducts | Can degrade oil quality and cause wear. | Signature Series Max-Duty Diesel Oil | Designed to maintain viscosity and protect against soot. | Requires adherence to service intervals. |
| Severe Towing/High Heat | Increases thermal stress on oil. | Signature Series 5W-40 | Excels in extreme temperatures and maintains viscosity. | Diagnosis of mechanical issues may still be required. |
| Engine Wear | High-stress diesel environments cause friction. | Signature Series Max-Duty Diesel Oil | Delivers up to 6X more wear protection based on third-party testing. | Does not repair existing damage. |
Common maintenance concerns for this vehicle
Based on the engine profile, owners of the 2015 Ford F-350 should consider the following practical checks:
- Fuel System Integrity: Essential for maintaining diesel engine performance.
- Turbocharger Health: Monitoring for any signs of turbocharger issues due to high-stress environments.
- Filter Restriction: Regularly checking air and oil filters to prevent restriction and ensure proper flow.
Recall, TSB, and manufacturer communication notes
NHTSA Recall Information:
One recall record was identified for the 2015 Ford F-350 Pickup:
- Campaign 25V270000 (Rearview Camera): The rearview camera printed circuit board terminal header connector may be loose or damaged, which can result in a blank or distorted image. This increases the risk of a crash by reducing driver visibility. Dealers will replace the rearview camera free of charge.
Note: Owners should verify open recalls by VIN through official Ford channels or the NHTSA website.
About this vehicle
The 2015 Ford F-350 is a prominent member of the Ford Super Duty series, a line of heavy-duty trucks engineered to exceed the capabilities of consumer-oriented models like the F-150. The Super Duty platform utilizes dedicated chassis components designed to support significantly higher payloads and more demanding towing requirements than lighter-duty vehicles.
A defining characteristic of this specific model is the Ford Power Stroke V8 diesel engine. This engine family is a cornerstone of Ford’s heavy-duty lineup, engineered specifically to provide the high torque necessary for commercial applications and heavy towing use cases. Because these engines are designed for high-stress environments, they require specialized maintenance considerations compared to standard gasoline engines.
The F-350 typically falls into Class 2 or Class 3 categories based on its Gross Vehicle Weight Rating (GVWR). It is frequently utilized in both pickup configurations and as a chassis cab for various commercial applications. Given the high-stress nature of these diesel variants, owners often research maintenance strategies involving high-quality filtration and strict adherence to fluid management protocols to ensure long-term reliability.
Maintenance Note: Users should verify exact engine codes and production nuances against the owner’s manual or official service documentation.
