It holds about 8 quarts (roughly 7.5 liters) of engine oil with a new filter installed.
The 2015 Silverado, equipped with the 5.3-liter V8 (EcoTec3), uses a standard oil capacity that is generally consistent across GM trucks. Exact amounts can vary slightly depending on whether the oil filter is replaced and other service details, so it’s best to confirm with the owner's manual or GM service data for your specific configuration.
Oil capacity specifics for the 5.3L V8
Below are the typical capacity figures you can expect when performing an oil change on the 5.3L V8. These numbers assume a standard drain and the installation of a new filter.
- Oil capacity with filter: 8 quarts (approximately 7.5 L).
- Oil capacity without filter: about 7 quarts (approximately 6.6 L).
These figures help you plan how much oil to have on hand for a routine change. After filling, always verify the level with the dipstick and top off if needed to reach the correct range.
Other oil-change considerations
In addition to quantity, use the correct grade and specification. For the 2015 Silverado 5.3L V8, GM recommends a Dexos1 Gen 2 approved 5W-30 motor oil. Use a filter that meets OEM standards. Check the oil level with the engine at operating temperature and after the engine has been off for a few minutes; the dipstick should read within the marked range.
Steps for checking and topping oil
Before performing a top-off or full oil change, gather the right tools and follow the steps below to ensure proper levels and filtration:
- Warm up the engine to operating temperature, then turn off and allow a few minutes for oil to settle.
- Remove the dipstick, wipe clean, reinsert, then pull out again to read the level.
- If low, add oil gradually in small increments, rechecking the level frequently to avoid overfill.
Following these steps helps ensure you maintain the correct oil volume and pressure for optimal engine performance.
Summary
The 2015 Chevy Silverado with the 5.3 L V8 typically takes 8 quarts (about 7.5 L) of engine oil with a new filter. Plan for roughly 7–8 quarts depending on whether the filter is changed, and always verify the level with the dipstick after filling. Use Dexos1 Gen 2 5W-30 oil and a compatible filter, and follow standard check-and-fill procedures to maintain proper oil level.
