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

For the 2004 Volkswagen Passat with the 2.0L 4-cylinder BHW diesel turbo engine, the oil capacity is 3.8 quarts (with filter). The recommended oil viscosity includes 5W-40 and 5W-30 for all temperatures. AMSOIL recommends using AMSOIL 5W-40 MS 100% Synthetic European Motor Oil<\/a> (AFLQT-EA<\/a>) and a MANN-FILTERS oil filter such as HU7262X-EA<\/a>.<\/p>\n

What oil does a 2004 Volkswagen Passat 2.0L TDI take?<\/h2>\n
