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

For the 1985 Ford Escort with the 2.0L 4-cylinder Engine Code [H] H Diesel, the oil capacity is 7.2 quarts (including the filter and bypass oil filter). The preferred viscosity for most operating temperatures is SAE 10W-30. AMSOIL recommends using Signature Series 10W-30 100% Synthetic Max-Duty Diesel Oil<\/a> (DTTQT-EA<\/a>) for outstanding extreme-pressure protection.<\/p>\n

What oil does a 1985 Ford Escort 2.0L Diesel take?<\/h2>\n

The engine requires an oil with the CH-4 specification. Depending on your ambient temperature, different viscosities are recommended to ensure proper lubrication and protection.<\/p>\n
