What oil does a 1981 Chevrolet Chevette 1.8L Diesel take?<\/h2>\n

For the 1981 Chevrolet Chevette with the 1.8L 4-cylinder Engine Code [D] Diesel, the recommended oil viscosity depends on ambient temperature: use 10W-30 for temperatures below 38\u00b0C, 15W-40 (preferred) for temperatures above -10\u00b0C, and 30 for temperatures above 0\u00b0C. The engine requires an oil grade of CF. AMSOIL recommends using Signature Series 15W-40<\/a> or Heavy-Duty 15W-40<\/a> synthetic diesel oil.<\/p>\n

The engine oil capacity is 6.1 quarts when performing a service with a filter change. Always check the oil level after refilling.<\/p>\n
