Before using this Buick Century oil chart

Use this chart as a reference before buying oil or filters. Final oil capacity, viscosity, filter fitment, and VW/Audi approval standard should be confirmed with the owner’s manual, oil cap, under-hood label, or dealer.

Buick Century GM Dexos Approval Reminder

Many Buick Century engines require Dexos approved lubricants (e.g., Dexos 1 Gen 3 or DexosD). Confirm the correct standard before buying oil.

Severe Service Change Intervals

Short trips, long idling, dusty roads, extreme heat or cold, aggressive driving, frequent stop-and-go traffic, and repeated city use can justify a shorter oil change interval. Follow the severe-service schedule in the owner’s manual when it applies.

Buick Century DIY Oil Buying Guide

Most Buick Century records on this page are near 6.0 quarts with filter, but some years differ. After selecting the exact year, buy enough oil to cover the listed capacity and keep a small reserve for top-off. Add oil gradually and recheck the level instead of pouring the full amount at once. Oil change prices vary by shop, oil approval, filter type, location, and engine. Use the listed capacity to estimate oil quantity, then compare local shop quotes or DIY parts cost.

DIY Oil Change Checklist

Confirm year and engine block displacement

Check exact quarts required with filter

Buy correct SAE viscosity grade (e.g. 0W-20 or 5W-30)

Confirm Buick approval standards

Use a filter that matches the exact Buick Century year, engine, and housing style. Do not buy filters by make and model alone.

Do not overfill — top off gradually

Buick Century Oil Capacity Guide

The Buick Century is a model from Buick with oil requirements that vary by engine and year. The published records on this page show multiple oil grades and a capacity range from 4.2 to 6.0 quarts with filter.

Do not choose oil by model name alone. A 2000 Buick Century and a newer 2005 Buick Century may use different oil grade, interval, capacity, or approval requirements.

After selecting your exact year, confirm the oil capacity with filter, oil grade, filter note, and service interval before buying oil or booking an oil change. Correct lubrication supports proper lubrication, correct oil pressure, and safe refill level when the correct grade, approval, capacity, and filter are used.
