In brief, the 2016 Buick Regal typically requires about 5 quarts of engine oil, with the exact amount depending on the engine option in your car. Check the owner's manual or your VIN for the precise figure.
Engine options in the 2016 Buick Regal
The 2016 Regal offered at least two gasoline engine options: a 2.0-liter turbocharged inline-4 (LTG) and, in some configurations, a 2.4-liter inline-4. Each variant has its own official oil capacity figure.
2.0L turbocharged engine (LTG)
Oil capacity for the 2.0L turbo LTG engine is about 5.0 quarts with filter (roughly 4.7 liters). This can vary slightly by model year and production batch; always verify for your exact VIN.
- Oil capacity (with filter): about 5.0 quarts
- Recommended oil viscosity: typically 5W-30
- Oil type: synthetic dexos1 Gen 2 or equivalent as specified by GM
Note: Use the GM-recommended oil and keep to the maintenance schedule for oil changes. The exact capacity may differ by market and vehicle configuration.
2.4L engine
Oil capacity for the 2.4L engine used in some Regal models is around 5.0 to 5.5 quarts with filter (roughly 4.7–5.2 liters). Confirm the exact figure using the owner’s manual or a dealer, particularly if your car has ancillary equipment that affects capacity.
- Oil capacity (with filter): about 5.0–5.5 quarts
- Recommended oil viscosity: typically 5W-30
- Oil type: synthetic dexos1 Gen 2 or equivalent as specified by GM
Again, verify the correct capacity for your VIN and engine configuration to avoid over- or under-filling.
Maintenance tips and checking oil
Regular oil level checks help ensure you are within the proper range between changes. To check the level, park on level ground, wait a few minutes after engine shutdown, and read the dipstick. When you perform an oil change, replace the filter and seal the drain plug properly, then fill to the recommended level.
Summary
The 2016 Buick Regal's oil capacity is around 5 quarts for its main petrol engines, with a possible range of roughly 5.0–5.5 quarts depending on engine type and configuration. Always confirm the precise figure for your vehicle using the owner's manual or by contacting a Buick dealer, and use a dexos1 Gen 2 5W-30 synthetic oil as recommended by GM.
