AMSOIL diesel oil guide for trucks, vans, SUVs and diesel engines<\/figcaption><\/figure>\n

For the 2014 Ford F-250 HD Pickup with the 6.7L 8-cylinder Diesel Turbo engine (Engine Code T), the oil capacity is 13.1 quarts<\/strong> (including filter). Recommended viscosities vary by temperature: 10W-30 is recommended for normal usage, while 5W-40 is suggested for severe operations or when using biodiesel blends (up to B20). AMSOIL recommends using Signature Series Max-Duty Synthetic Diesel Oil<\/strong> paired with an AMSOIL Oil Filter<\/strong> for optimal protection.<\/p>\n

What oil does a 2014 Ford F-250 HD 6.7L Diesel take?<\/h2>\n

The required oil viscosity depends on your operating environment and fuel type. For normal usage, the manufacturer recommends 10W-30. For severe operations, 5W-40 is recommended. If you are using biodiesel blends (up to B20), it is recommended to use either 5W-40 or 15W-40 oil.<\/p>\n

AMSOIL product recommendations<\/h2>\n

To simplify your maintenance, AMSOIL provides several high-performance oil and filter combinations specifically suited for the Ford Power Stroke diesel engine. Below are the primary recommendations based on your service needs.<\/p>\n

How much oil does it take with a filter change?<\/h2>\n

The engine requires 13.1 quarts<\/strong> of oil when performing a service that includes the replacement of the oil filter. It is essential to check the oil level after refilling to ensure accuracy.<\/p>\n

Manufacturer Specification Note:<\/strong> The AMSOIL lookup note references Ford Material Engineering Specification WSS-M2C171-F1. In 2016, Ford superseded the original recommendation of WSS-M2C171-D with WSS-M2C171-F1.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 the 6.7L diesel engine rather than standard CK-4 motor oils, as testing has shown some CK-4 formulations may provide inadequate wear protection compared to earlier CJ-4 formulations.<\/p>\n

Common diesel oil-related concerns and how AMSOIL products may help<\/h2>\n

Diesel engines operating under heavy loads or in extreme environments face unique lubrication challenges. The following table outlines common concerns and how specific AMSOIL products can support engine longevity.<\/p>\n
