The 2.5-liter Buick Envision typically requires about 4.7 quarts (4.4 liters) of engine oil when performing a full oil change with a new filter. Exact capacity can vary by model year and engine variant, so always verify with the owner's manual or your dealer.
Typical capacity and what can affect it
The figures below reflect a standard oil change with a new filter. Variations between years or trims can shift the total slightly, so use these as a guideline and confirm with official documentation for your vehicle.
- With the oil filter replaced: 4.7 quarts (approximately 4.4 liters)
- Without the oil filter: about 4.0 quarts (approximately 3.8 liters)
When you finish filling, always verify the oil level using the dipstick and adjust to the full mark as needed. If you’re unsure, consult the owner’s manual or a Buick service professional for your specific year and engine variant.
Oil type and specifications
The Buick Envision 2.5L generally requires a Dexos1 Gen 2 approved oil, most commonly 0W-20 synthetic. Use the grade specified in your owner's manual and ensure the oil meets Dexos1 Gen 2 standards to maintain warranty coverage and optimal engine protection.
- Dexos1 Gen 2 0W-20 synthetic (preferred)
Always check the exact specification in your manual, as some markets or model years may have slight variations in approved oil grade.
Change intervals and oil level checks
Oil change intervals are influenced by driving conditions and the vehicle’s oil life monitoring system. In typical conditions, GM often recommends following the oil life monitor, with changes around every 7,000–7,500 miles (about 11,000–12,000 kilometers) under normal use; severe conditions can shorten that interval.
- Park on level ground and let the engine cool for a few minutes after driving, or run it to operating temperature if you’re performing a scheduled change.
- Drain old oil and replace the oil filter, then add the recommended amount of new oil.
- Check the oil level with the dipstick, ensuring it reads within the full range.
- Reset or check the vehicle’s oil life monitor if applicable after an oil change.
- Dispose of used oil responsibly at a recycling facility or service center.
Following these steps helps ensure your Envision's engine stays properly lubricated and protected between changes.
Summary
For a 2.5 L Buick Envision, plan on about 4.7 quarts (4.4 liters) of engine oil when performing a full change with a filter. Use Dexos1 Gen 2 0W-20 synthetic oil, and follow the vehicle’s oil life monitor for change intervals, typically around 7,500 miles under normal driving. Always verify the exact capacity and grade in your owner's manual for your specific year and engine variant.
