The 2001 Ford Excursion with the 7.3L 8-cylinder Engine Code [F] requires an oil capacity of 15 quarts<\/strong> (including filter). Recommended viscosities based on ambient temperature include 15W-40<\/strong> for temperatures above -12\u00b0C, 10W-30<\/strong> for -23\u00b0C to 32\u00b0C, 5W-30<\/strong> for below -1\u00b0C, and 0W-30<\/strong> for below -18\u00b0C. AMSOIL recommends the Signature Series 15W-40<\/a> for this application.<\/p>\n

Engine Oil Specifications & Details<\/h2>\n

What is the oil capacity for a 7.3L Power Stroke?<\/h3>\n

The total capacity is 15 quarts<\/strong> when replacing the filter. When refilling, it is important to remove the dipstick to provide adequate venting and allow the oil to flow into the crankcase properly. Always check the oil level after refill and top off as needed.<\/p>\n

OEM Specification Notes<\/h3>\n

The AMSOIL lookup note references Ford Material Engineering Specification WSS-M2C171-F1<\/strong>. The notes indicate that for older diesel engines like the 7.3L, Ford continues to recommend oils meeting WSS-M2C171-F1 rather than CK-4 motor oils. This is because testing on some CK-4 formulations has shown inadequate wear protection compared to previous CJ-4 formulations.<\/p>\n
