What oil does a 2004 Ford Excursion 6.0L Diesel take?<\/h2>\n

The 2004 Ford Excursion with the 6.0L 8-cylinder Engine Code [P] requires an oil capacity of 15 quarts (with filter). Recommended viscosities vary by temperature: 15W-40 is preferred for temperatures above -1\u00b0C (31\u00b0F), while 10W-30 is preferred for operating temperatures between -20\u00b0C (-4\u00b0F) and -1\u00b0C (31\u00b0F). AMSOIL recommends Signature Series 15W-40 Max-Duty Diesel Oil<\/a> for this application.<\/p>\n

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

OEM Specification Notes<\/h3>\n

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 Note that in 2016, Ford superseded the original recommendation of WSS-M2C171-D with WSS-M2C171-F1.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.<\/p>\n

Automatic Transmission Fluid (ATF) Details<\/h2>\n

For vehicles equipped with the 4R100 transmission, maintenance is critical for heavy-duty performance.<\/p>\n
