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

What oil does a 2018 Ford Transit 350 3.2L Diesel take?<\/h2>\n

For the 2018 Ford Transit 350 with the 3.2L 5-cylinder diesel engine, the required oil capacity is 12 quarts with a filter change. Recommended viscosities include 0W-30 or 0W-40 for all temperatures, and 5W-30 or 5W-40 for temperatures above -29\u00b0C. AMSOIL recommends using Signature Series 0W-40 100% Synthetic Max-Duty Diesel Oil<\/a> for optimal protection.<\/p>\n
