Engine Oil Specifications<\/h3>\n

The AMSOIL lookup note references Ford Material Engineering Specification WSS-M2C171-F1. It notes that Ford superseded the original ESE-M2C153-E recommendation with this specification. Furthermore, Ford has indicated that for older diesel engines like the 7.3L, they recommend oils meeting WSS-M2C171-F1 rather than CK-4, as some CK-4 formulations may show inadequate wear protection compared to earlier CJ-4 formulations.<\/p>\n

Maintenance 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 as needed.<\/p>\n

How much transmission fluid does it take?<\/h2>\n

The capacity depends on your specific automatic transmission model. For the 4-speed E4OD, the total fill is 15.5 quarts, with an initial fill of 8.5 quarts. For the 3-speed C6, the total fill is 11.8 quarts, with an initial fill of 5.9 quarts.<\/p>\n

Note: The AMSOIL lookup notes that this specification has been updated from Mercon to Mercon V per TSB 06-14-4.<\/em><\/p>\n
