Capacities, torques and tune-up values from the factory service manual.

This engine holds 5.5 qt of 5W-30 API engine oil, 80W-90 · GL-5 in the differential, DOT 3 brake fluid. Torque lug nuts to 140 ft-lbs, the oil drain plug to 18.0 ft-lbs. The firing order is 1-8-4-3-6-5-7-2. Note the cylinder-head bolts finish on a torque angle (torque-to-yield) — they stretch permanently and should be replaced, not reused, during any head service.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.
