Chevy Maintenance Schedule: Silverado, Camaro, Corvette

Every Chevrolet covered here follows the same basic system. GM's Oil Life System tells you when the oil is due, with no fixed mileage, and the oil and filter must be changed at least once a year. Tire rotation and the Required Services come every 7,500 miles (12,000 km), the cabin air filter every 22,500 miles (36,000 km) or 24 months, and the engine coolant every 150,000 miles (240,000 km) or five years, which becomes six years from 2023. What changes between models is the spark plug interval, the transmission and axle fluids, and a few model-specific items.

This page lists what GM's US owner's manuals say across three models, then gives each one its generation, its model years and its headline intervals, with a link to the full guide. The figures come from the Silverado 1500 (T1XX generation, 2019–2026, with GM's 3.0L Duramax supplements), the Camaro (6th generation, 2016–2024) and the Corvette (C8, 2020–2026). Other Chevrolet models have no figures on this page, and neither do Silverado, Camaro or Corvette models built before the model years above.

How GM's Oil Life System works

The Oil Life System signals service with a CHANGE ENGINE OIL SOON message. GM gives none of the three models a fixed oil-change mileage. Its rules are the same on all of them:

• When CHANGE ENGINE OIL SOON appears, have the engine oil and filter changed within the next 600 miles (1,000 km).
• Under the best conditions the system may not ask for service for up to a year. The oil and filter must still be changed at least once a year, and the system must be reset after the change.
• The oil life percentage is checked at every 7,500-mile (12,000 km) service.
• If the oil life system is reset by accident, service the vehicle within 3,000 miles (≈4,800 km) of the last service.

Brake fluid	Replace every five years; three years for manual-transmission Camaros in 2018–2022	Silverado, Camaro, Corvette

Spark plugs and transmission fluids are not on this list because they differ by model, engine and year. Each model section below gives the headline figures.

The 7,500-mile service

GM labels this visit Tire Rotation and Required Services. In the earlier manuals the list includes a brake system inspection. From 2023 the visit is a Multi-Point Vehicle Inspection that includes a brake system check and, on the Silverado, Camaro and Corvette, a visual inspection and test of the 12-volt battery. The oil life percentage is also checked at this service.

Chevrolet Silverado 1500 (T1XX, 2019–2026)

The T1XX Silverado 1500 appears with the 2.7L turbo four-cylinder, the 4.3L V6 (2019–2021 only), the 5.3L and 6.2L V8s and the 3.0L Duramax turbo-diesel (2020–2026). The figures come from GM's owner's manual for each year and its Duramax supplements.

• Spark plugs: every 60,000 miles (96,000 km) on the 2.7L, and every 97,500 miles (156,000 km) on the 4.3L V6 and the 5.3L and 6.2L V8s.
• Transfer case fluid, 4WD only: every 97,500 miles (156,000 km) for 2019–2022, with a weight split in 2020, and every 100,000 miles (161,000 km) for 2023–2026.
• Automatic transmission fluid: no normal-service interval. Severe service only: every 45,000 miles (72,000 km). GM's severe service is mainly heavy city traffic in hot weather, hilly or mountainous terrain, frequent trailer towing, high-speed or competitive driving, or taxi, police or delivery use.

• Spark plugs: every 60,000 miles (96,000 km) on the 2.0L LTG and, from 2020, the LT4. Every 97,500 miles (156,000 km) on the 3.6L LGX and the 6.2L LT1, and on the LT4 in 2017–2019.
• Rear axle fluid: every 45,000 miles (72,000 km) with a limited-slip differential. Without one, every 150,000 miles (240,000 km) from 2020.
• Brake fluid: every five years, or every three years on manual-transmission cars in 2018–2022.

Chevrolet Corvette (C8, 2020–2026)

The C8 Corvette appears with the 6.2L LT2 V8 (including the E-Ray hybrid, 2024–2026), the 5.5L LT6 V8 of the Z06 (2023–2026), and the 5.5L LT7 twin-turbo V8 of the ZR1 (2025–2026) and the ZR1X (2026). The figures come from GM's owner's manual for each year.

• Dual-clutch transmission fluid: every 45,000 miles (72,000 km) or three years for 2023–2026. In 2020–2022 the Fluid Life System decides, with a three-year limit.
• Transmission external canister filter: first at 7,500 miles (12,000 km), then at 22,500 miles (36,000 km) and every 22,500 miles after that.
• Spark plugs: every 97,500 miles (156,000 km).

What GM does not schedule

A few items that generic checklists include have no interval in GM's schedules for these three models:

• A fixed oil-change mileage. The Oil Life System decides, with a one-year limit.
• Brake pad replacement on the Silverado and Corvette. GM's schedule lists only the brake system inspection.
• Silverado axle fluid. No replacement on the normal or the severe schedule.
• Corvette rear differential fluid. There is no such item. GM describes the dual-clutch transmission as containing an integrated rear differential.
• Transmission fluid on the Silverado and Camaro under normal service. Only severe service has an interval.

If a shop quotes one of these as a GM requirement, ask which GM document it comes from.

Other Chevrolet models

Other Chevrolet models have no figures on this page, and neither do Silverado, Camaro or Corvette models built before the years above. For those, use your owner's literature.
