Choosing the Right Oil for Your Buick or GMC
Using the correct motor oil is essential for engine performance and protection. Oil requirements vary by engine design, model year, operating conditions and manufacturer specifications.
ACDelco GM OE Full Synthetic Oil
GM-approved synthetic oil formulations are designed to meet applicable engine specifications and help protect against wear, deposits and sludge.
Mobil 1 Full Synthetic Oil
Mobil 1 offers advanced synthetic lubrication products. The correct grade and approval must match your vehicle's requirements.
Diesel Engine Oil
GMC Duramax diesel engines may require different oil specifications and service procedures than gasoline engines. Our team can help identify the appropriate requirements.
Always follow the oil viscosity, specification and service interval stated in your vehicle owner's manual. Oil products and availability vary.
How Often Should You Change Your GMC or Buick Oil?
There is no single oil-change interval that applies to every modern GM vehicle. Many Buick and GMC models use an Engine Oil Life System that monitors operating conditions to help determine when maintenance is needed.
Your oil-change needs may depend on:
- Vehicle model, year and engine.
- Highway versus stop-and-go driving.
- Frequent towing or hauling.
- Cold-weather driving and short trips.
- Engine operating temperatures.
- Manufacturer maintenance requirements.
Wisconsin winters, repeated short trips and frequent towing can affect vehicle maintenance needs. Follow your owner's manual and Oil Life System, and check the oil level regularly.
If your vehicle displays an oil-change reminder, contact Sommer's Buick GMC to arrange service.

Why choose a GM Certified Service Center for an oil change?
