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

For the 1983 Pontiac Grand Prix with the 5.7L 8-cylinder Diesel engine (Code N), the oil capacity is 7 quarts<\/strong> (including filter replacement). Recommended viscosities include 10W-30<\/strong> for temperatures below 16\u00b0C, 15W-40<\/strong> for -18 to 16\u00b0C, and 30 weight<\/strong> for continuous driving above 0\u00b0C. AMSOIL recommends Signature Series 10W-30 Max-Duty Diesel Oil<\/a> for superior protection.<\/p>\n

What oil does a 1983 Pontiac Grand Prix 5.7L Diesel take?<\/h2>\n

The engine requires an oil with a CF grade specification. Depending on your operating environment, you should select the appropriate viscosity: 10W-30 for temperatures below 16\u00b0C, 15W-40 for temperatures between -18 to 16\u00b0C, or a 30 weight oil for continuous driving in temperatures above 0\u00b0C.<\/p>\n

How much transmission fluid does it take?<\/h2>\n

Capacity varies significantly depending on your specific automatic transmission model. For the THM200-4R, the total fill is 11 quarts with a 5-quart initial fill. The THM700-R4 also requires an 11-quart total fill and 5-quart initial fill. The THM350C requires a 10-quart total fill and 3-quart initial fill, while the THM200C requires a 9.4-quart total fill and 3.5-quart initial fill.<\/p>\n
