How often should I change the oil on a 2019–2025 Chevy Silverado 1500?

Chevrolet uses an Oil Life Monitor (OLM) on all 2019–2025 Silverado 1500 trucks rather than a fixed mileage interval, but most owners see service called for between 5,000 and 7,500 miles under normal conditions, or every 12 months — whichever comes first. Under severe conditions (towing, dusty environments, extreme cold, heavy idling, or short trips), expect the OLM to call for service closer to 3,000–5,000 miles. Never exceed 12 months regardless of mileage.

What is the OEM oil filter for the 2019–2025 Silverado 1500 5.3L and 6.2L V8?

Both the 5.3L L84 and 6.2L L87 V8 engines use ACDelco PF63 (GM part number 12735811). This filter replaced the older PF26 and is the current production part for all 2019–2025 Silverado 1500 trucks with V8 engines. The 2.7L Turbo uses a different filter — ACDelco PF66 — and the 3.0L Duramax diesel uses its own dedicated filter.

What oil does the 6.2L L87 take after the GM recall?

It depends. The original spec for all 2019–2024 6.2L L87 engines was 0W-20 Dexos1 Gen 3. Following GM safety recall N252494000 (NHTSA 24V-795), 2021–2024 trucks that pass dealer inspection get an oil change to 0W-40 Dexos R (typically Mobil 1 FS 0W-40) and a new oil fill cap. Engines that are replaced under the recall retain the original 0W-20 spec. 2019, 2020, and 2025 model year trucks are not part of the recall and continue to use 0W-20. Always check your VIN at NHTSA.gov/recalls and follow whatever your fill cap currently says.

What oil does the 2.7L Turbo Silverado take?

The 2.7L L3B turbocharged 4-cylinder uses 5W-30 Dexos1 Gen 3 full synthetic — not 0W-20 like the V8s. Capacity is 6 quarts with filter. The OEM oil filter is ACDelco PF66. This is one of the most common DIY mistakes on the Silverado: using V8 filter and oil specs on the 2.7L. Always verify before ordering parts.

What oil does the 3.0L Duramax diesel Silverado take?

The 3.0L LM2 (2020–2022) and 3.0L LZ0 (2023+) Duramax inline-six diesel uses 0W-20 Dexos D full synthetic. Capacity is 7 quarts with filter. Dexos D is a diesel-specific spec — do not substitute Dexos1 Gen 3, which is intended for gasoline engines. The Duramax also has a separate fuel filter service interval that the gas engines don't have.

What does T1XX mean for the Silverado 1500?

T1XX is GM's internal platform code for the 4th generation Silverado 1500 (and the related GMC Sierra 1500, Tahoe, Suburban, Yukon, and Cadillac Escalade) covering the 2019–2025 model years. It distinguishes this generation from the K2XX platform (2014–2018). Knowing your platform code helps confirm you're ordering the correct OEM parts — many filters and fluids carried over, but several were redesigned for the T1XX.

Is there an app to track Chevy Silverado 1500 maintenance?

Yes — CarMaintenance.App is a free iOS app that tracks all service intervals for your Silverado, sends push reminders before each one hits, and supports all four T1XX powertrains including the L87 recall oil change tracking. No subscription required.
