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

For the 1997 Ford F-250 HD Pickup with the 7.3L 8-cylinder Diesel Turbo (Engine Code F), the engine oil capacity is 13.9 quarts<\/strong> with a filter change. Depending on your operating temperature, preferred viscosities include SAE 10W-30<\/strong> for temperatures between -23\u00b0C to -1\u00b0C and SAE 15W-40<\/strong> for temperatures above -1\u00b0C. AMSOIL recommends the Signature Series 15W-40 Max-Duty Diesel Oil<\/a> paired with an AMSOIL Oil Filter<\/a>.<\/p>\n

What oil does a 1997 Ford F-250 HD 7.3L Diesel take?<\/h2>\n

The 1997 Ford F-250 HD with the 7.3L diesel engine requires specific viscosities based on ambient temperature. For temperatures between -23\u00b0C and -1\u00b0C, SAE 10W-30 is preferred. For operating conditions above -1\u00b0C (31\u00b0F), SAE 15W-40 is the preferred viscosity. Below 10\u00b0C, 5W-30 may be considered.<\/p>\n

Note on OEM Specifications:<\/strong> The AMSOIL lookup note references Ford Material Engineering Specification WSS-M2C171-F1 for this application. It notes that Ford superseded the original ESE-M2C153-E recommendation with WSS-M2C171-F1 and continues to recommend oils meeting this specification over CK-4 motor oils for older 7.3L diesel engines.<\/p>\n

Engine Oil Capacity<\/h3>\n

Capacity:<\/strong> 13.9 quarts (with filter change).<\/p>\n

Refilling Tip:<\/strong> When refilling, remove the dipstick to provide adequate venting and allow oil to flow into the crankcase. After refill, always check the oil level and top off to the proper level as needed.<\/p>\n

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

Maintaining a 7.3L Power Stroke requires addressing specific heavy-duty operational stresses.<\/p>\n
