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

For the 1982 GMC Jimmy with the 6.2L 8-cylinder Diesel engine (Engine Code C), the oil capacity is 7 quarts with a filter change. Recommended viscosities include 10W-30 for temperatures below 16\u00b0C, 15W-40 for -18 to 16\u00b0C, and SAE 30 is preferred for temperatures above 0\u00b0C. AMSOIL recommends using the Signature Series 10W-30 Max-Duty Diesel Oil<\/a> (DTTQT-EA<\/a>) paired with an AMSOIL Oil Filter<\/a> (EAO24-EA<\/a>) for optimal protection.<\/p>\n

What oil does a 1982 GMC Jimmy 6.2L Diesel take?<\/h2>\n

The engine requires an oil with the CF-4 specification. Depending on your operating environment, you should select a viscosity that matches local temperatures: 10W-30 for temperatures below 16\u00b0C, 15W-40 for -18 to 16\u00b0C, or SAE 30 if temperatures are consistently above 0\u00b0C. Always check the oil level after refilling.<\/p>\n
