The 2014 Buick 3.6L V6 typically requires about 5 quarts of engine oil (4.7 liters) when changing the oil, including a new filter. Always verify with your owner’s manual for your exact model, since tiny variations can occur by trim and configuration.
Context and engine family
In 2014, Buick used the 3.6-liter V6 across several models, including the LaCrosse and Enclave, among others. This engine group generally lists an oil capacity around 5 quarts with a filter. Because variations can exist between different Buick models that share the 3.6L family, consult the specific manual for the precise figure for your car.
Oil capacity by model
Below are the typical figures you may encounter in manuals and service guides for Buick models that use the 3.6L V6 in 2014. These values refer to capacity with a new filter installed.
- LaCrosse 3.6L V6: 5 quarts (4.7 L) with filter
- Enclave 3.6L V6: 5 quarts (4.7 L) with filter
- Other 3.6L Buick models from the same era generally align with the same ~5-quart capacity when a new filter is used
In short, the practical oil-fill expectation for most 2014 Buick models equipped with the 3.6L V6 is about 5 quarts of oil with a new filter. Always confirm with the owner’s manual or a GM service bulletin for your exact vehicle configuration.
DIY oil-change steps
Before starting the list, note the following general approach for a typical oil change on a 3.6L Buick. This sequence helps ensure you remove old oil completely, replace the filter, and fill to the correct level.
- Gather supplies: the correct 5W-30 (or as specified in your manual), the correct oil filter, a drain pan, a funnel, a wrench for the drain plug, and safety equipment.
- Warm up the engine lightly so the oil drains more completely, then park on a level surface and engage the parking brake.
- Carefully raise the vehicle and support it securely if needed to access the drain plug.
- Place the drain pan under the oil pan, remove the drain plug, and allow the old oil to drain completely.
- Remove the old oil filter, replace it with a new filter, and reinstall the drain plug.',
title='oil-change-steps' - Pour in about 4–5 quarts of new oil (start with 4.5–4.7 quarts, then check the level with the dipstick and top up to the full mark as needed).
- Start the engine, idle briefly, and check for leaks around the filter and drain plug; turn off the engine and recheck the oil level after a few minutes with the dipstick, topping off if necessary.
- Dispose of used oil and filters properly and reset the oil-life monitor if your vehicle has one.
Following these steps helps ensure you achieve the correct oil level and maintain engine health after an oil change.
Choosing the right oil and maintenance notes
For the 3.6L V6 in many GM vehicles, use a 5W-30 viscosity that meets OEM specifications. Synthetic or synthetic-blend oils are commonly recommended for better protection and longer intervals between changes. Always refer to the owner’s manual for the exact viscosity and any Dexos specification requirements, and follow the recommended service interval based on your driving conditions.
Summary
The 2014 Buick 3.6L V6 engine typically takes about 5 quarts of oil with a new filter. While this is standard across common 3.6L Buick models, always verify the exact capacity in your owner’s manual, as configurations can differ. When performing an oil change, drain the old oil completely, replace the filter, and fill to the full mark on the dipstick after one final check. Use the oil type and maintenance schedule recommended by Buick/GMC for your specific model.
