Quick Summary for 2014 Ford F-450 6.7L Diesel<\/h2>\n

For the 2014 Ford F-450 Pickup with the 6.7L 8-cylinder Engine Code [T] A Diesel Turbo, the oil capacity is 13.1 quarts<\/strong> (including filter). Recommended viscosity depends on ambient temperature: 10W-30 for normal usage and 5W-40 for severe operations. For biodiesel fuel blends (B20 max), use of 5W-40 or 15W-40 is recommended. AMSOIL recommends the Signature Series Max-Duty Synthetic Diesel Oil<\/strong> paired with an AMSOIL Oil Filter<\/strong> for optimal protection.<\/p>\n
