Buick Engine Oil Guide
Every Buick model has specific oil requirements set by the manufacturer. Using the correct viscosity grade is critical — the wrong oil can reduce fuel economy, increase engine wear, and in some cases void your powertrain warranty.
Our database covers 217 Buick vehicles spanning from 2000 through 2026, giving you the exact oil grade (e.g. 0W-20, 5W-30), capacity in US quarts, compatible oil filter part number, and manufacturer-recommended service interval for every model.
Whether you drive a Buick Cascada, a Enclave AWD, or a Verano, the correct oil specification is just two clicks away — select your model above, then your year.
Buick oil change intervals vary by model and year. Modern Buick vehicles (2015 and newer) typically use full synthetic oil with intervals of 7,500 to 10,000 miles. Older models may require conventional or synthetic blend oil changed every 5,000 miles or 6 months.
For Buick vehicles, using the manufacturer-specified oil filter is equally important. Each model page shows a compatible aftermarket filter (Fram, Mobil 1, or OEM equivalent) alongside the oil specs so you have everything needed for a complete service.
Always cross-reference with your vehicle's owner's manual for the most accurate specification, especially for newer models or special trim levels with different engine configurations.
Most modern Buick vehicles use 0W-20 or 5W-30 full synthetic. Check your specific model for exact grade.
Typically 5,000–10,000 miles depending on year and oil type. Severe driving reduces this by 25–30%.
Most Buick oil changes cost $45–$95 at a shop, or $25–$50 in parts for a DIY change.
