What oil does a 2018 Ford F-450 6.7L Diesel take?<\/h2>\n

The 2018 Ford F-450 with the 6.7L 8-cylinder Engine Code [T] O Diesel Turbo requires an oil capacity of 13 quarts<\/strong> (including filter replacement). Recommended viscosities include 10W-30 for normal usage and 5W-40 for severe operations. For those using biodiesel fuel blends (up to B20), the manufacturer recommends using 5W-40 or 15W-40 oil. AMSOIL recommends the Signature Series Max-Duty Synthetic Diesel Oil for superior protection.<\/p>\n
