Oil Maintenance & Service Tips
Check engine oil level monthly using the dipstick on a level surface after the engine cools. Park on flat ground, remove the dipstick, wipe it clean, reinsert fully, and pull out to read between add and full marks. Add oil slowly if low, using the recommended type and viscosity to avoid overfill.
During oil changes, drain old oil when hot, replace the filter by hand to avoid damage, and torque the drain plug to spec. Use a new crush washer if provided. Reset the oil life monitor via the dashboard after service for accurate tracking.
For synthetic oil, select dexos1-approved products for GM engines. Replace the oil filter every change to capture contaminants. Follow the maintenance interval based on driving habits.
| Condition | Interval Adjustment |
|---|---|
| Normal Driving | Every 7,500 miles or 12 months |
| Severe Driving | Every 3,000-5,000 miles or 6 months (towing, short trips, dusty roads) . |
FAQs
What kind of oil does a Buick LaCrosse use?
Buick LaCrosse models from 2005 to 2019 primarily use full synthetic or synthetic blend SAE 5W-30 oil, with later engines like the 2.5L I4 eAssist requiring SAE 0W-20 full synthetic. The oil type must meet GM dexos1 standards for compatibility. Check the owner’s manual for engine-specific details to ensure proper lubrication.
How much oil does a Buick LaCrosse take?
Oil capacity varies by engine: 4.7-5.3 qt for inline-4 models and 5.5-6.0 qt for V6 engines, including filter. For example, the 3.6L V6 holds 6.0 qt with filter. Always verify the exact amount post-change using the dipstick to prevent under or overfilling.
What is the recommended oil type for a Buick LaCrosse?
Recommended oil is full synthetic SAE 5W-30 for most V6 and I4 engines up to 2016, shifting to SAE 0W-20 full synthetic for 2017-2019 eAssist models. Synthetic provides better thermal stability and wear protection than conventional. Use API SN or higher rated oils for compliance.
What is the oil change interval for a Buick LaCrosse?
The standard interval is every 7,500 miles or 12 months for synthetic oil in normal conditions, dropping to 5,000 miles for earlier models with blend oil. Severe conditions like frequent short trips shorten it to 3,000 miles. The oil life system alerts when service is due.
What viscosity is best for Buick LaCrosse engine oil?
SAE 5W-30 suits most 2005-2016 engines for balanced flow in varied temperatures, while SAE 0W-20 fits 2017-2023 models for improved efficiency. Stick to manufacturer specs to maintain fuel economy and engine protection. Avoid mixing viscosities during top-offs.
Does Buick LaCrosse require synthetic oil?
Yes, full synthetic is recommended for 2010+ models to meet dexos1 requirements and extend service life. Earlier years can use synthetic blend SAE 5W-30 effectively. Synthetic oil resists breakdown better in modern engines.
Conclusion
Buick LaCrosse engine oil capacity ranges from 4.7 qt to 6.0 qt with filter, depending on the engine like 2.4L I4 or 3.6L V6. Viscosity is typically SAE 5W-30 or 0W-20, with full synthetic as the preferred type for protection. Use manufacturer-approved oil to match specifications.
Proper maintenance with these details ensures engine reliability. Follow intervals for sustained performance and reduced repairs.
