The Chevrolet Silverado 1500 comes with several engines, and GM has shifted oil grades over the years, so knowing your exact engine matters. Newer V8s often specify 0W-20, while older ones used 5W-30, and the turbo four-cylinder has its own grade. Here is the breakdown by engine and year.
| Engine / Years | Oil type | Capacity | Interval |
|---|---|---|---|
| 5.3L V8 2019-2025 | 0W-20 dexos | 8.0 qt | 7,500-10,000 mi |
| 6.2L V8 2019-2025 | 0W-20 dexos | 8.0 qt | 7,500-10,000 mi |
| 5.3L / 6.2L V8 2014-2018 | 5W-30 dexos | 8.0 qt | 7,500 mi |
| 2.7L turbo 2019-2025 | dexos per manual | 6.0 qt | 7,500-10,000 mi |
GM specifies a dexos-approved oil for the Silverado, and the grade depends on the engine. The 5.3L and 6.2L V8s in recent years use 0W-20, while earlier V8s used 5W-30. The 2.7L turbo four-cylinder uses a dexos oil as specified in the manual, and the 3.0L Duramax diesel uses a 0W-20 diesel-rated oil.
Always use an oil that carries the GM dexos certification, which is printed on qualifying bottles.
The 5.3L V8 holds about 8 quarts with a filter change, and the 6.2L V8 holds roughly 8 quarts as well. The 2.7L turbo holds about 6 quarts. The 3.0L Duramax diesel holds around 7.4 quarts. Always confirm on the dipstick.
The Silverado uses a spin-on oil filter. Because the V8s hold about 8 quarts, use a large drain pan and buy enough oil. Gather a dexos oil in the correct grade, a compatible filter, and the right drain-plug socket. Reset the oil-life monitor through the dash after the change.
