The 2021 Cadillac XT5 generally requires about 5 quarts of engine oil with the filter, regardless of which engine you have. Always verify with your owner’s manual or service guide for the exact specification for your vehicle.
In 2021, the XT5 offered two engine options: a 3.6L V6 and a 2.0L turbo four. Both share the same basic oil capacity when you replace the oil filter, but exact specs can vary by engine code and configuration. The following section summarizes the engines and their official oil capacity.
Engine options and official oil capacity
Before listing the engines, note that the XT5’s official oil capacity is given as the amount needed with the oil filter installed. This helps ensure you have enough oil after a full change and filter replacement.
- 3.6L V6 (LGX): Oil capacity with filter ≈ 5.0 quarts
- 2.0L Turbo I4 (LTG): Oil capacity with filter ≈ 5.0 quarts
Conclusion: For an oil change on a 2021 XT5 using either engine, plan for about 5 quarts of oil with the filter. Use a synthetic oil that meets GM dexos1 specification, and verify the exact capacity on the under-hood label or in the owner’s manual for your specific VIN and production date.
Oil type and grade
Use synthetic engine oil meeting GM dexos1 specification, typically with a viscosity of 0W-20 for both available engines. Stick to the manufacturer’s recommendation and avoid mixing different oil grades. Always use the correct filter and follow the service interval guidelines provided by Cadillac for your model and driving conditions.
Maintenance tips for oil changes
When performing an oil change, ensure you replace the oil filter, reset the oil life monitor if applicable, and dispose of the old oil properly. After refilling, recheck the level with the dipstick and top off as needed to reach the full-mark on the dipstick.
Summary
The 2021 Cadillac XT5 uses about 5 quarts of engine oil with the filter for its two available engines (3.6L V6 and 2.0L Turbo). Confirm the exact capacity for your VIN by consulting the owner’s manual or the under-hood oil specification label, and use a synthetic 0W-20 dexos1-approved oil to ensure optimal performance and protection.
