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

What oil does a 2012 Ford F-250 HD 6.7L Diesel take?<\/h2>\n

For the 2012 Ford F-250 HD with the 6.7L 8-cylinder ‘Code T’ Turbo Diesel engine, 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 the Signature Series 10W-30<\/strong> or 5W-40<\/strong> Max-Duty Diesel Oils for optimal protection.<\/p>\n

AMSOIL product recommendations<\/h2>\n

Manufacturer Specification Notes<\/h3>\n

The AMSOIL lookup note references Ford Material Engineering Specification WSS-M2C171-F1<\/strong> for this application. The notes indicate that Ford superseded the original WSS-M2C171-D recommendation with WSS-M2C171-F1 in 2016 to provide additional wear protection beyond standard CK-4 requirements.<\/p>\n
