Standing in the oil aisle staring at a wall of bottles? You’re not alone. If you’ve ever asked yourself “What oil does my Chevy take?” our service team at Beaty Chevrolet in Knoxville hears that question all the time, and the honest answer is that it depends on the engine under your hood. Here’s a model-by-model breakdown, plus an explanation of why the right oil matters more than most drivers realize.
Key Takeaways
- Most current Chevrolet gas engines call for Dexos1-approved 0W-20 oil, including the Equinox, Traverse, Trax, Trailblazer, Tahoe, Suburban, and Silverado 1500 V8s.
- The Silverado 1500's 2.7L TurboMax, the Silverado HD's 6.6L gas V8, and the Blazer's 3.6L V6 use Dexos1-approved 5W-30 instead.
- The 3.0L Duramax diesel requires DexosD 0W-20, while the 6.6L Duramax in Silverado HD trucks uses 15W-40 oil with an API CJ-4 or CK-4 rating.
- Oil capacity ranges from about 4.2 quarts in a Trax to 10 quarts in a Duramax-equipped Silverado HD.
- Chevrolet's Oil Life Monitoring System tells you when an oil change is due based on how you actually drive.
What Oil Does Each Chevrolet Model Take?
Most late-model Chevrolet gas engines take Dexos1-approved 0W-20 oil. Turbocharged truck engines and larger gas V8s built for heavy work often call for 5W-30, and diesel engines have their own specifications. Here’s a quick look at Chevy oil type by model.
Trucks are where it gets interesting, because your Silverado oil type depends on the engine rather than the badge. A Silverado 1500 with the 5.3L or 6.2L V8 takes 0W-20, while the 2.7L TurboMax and the 6.6L gas V8 in the Silverado 2500 HD and 3500 HD use 5W-30. The Duramax diesels are a separate category altogether.
Crossovers and SUVs are simpler. The Trax, Trailblazer, Equinox, Traverse, Tahoe, and Suburban gas engines all use 0W-20. One detail that trips people up is Equinox oil capacity: front-wheel-drive models hold about 4.2 quarts with the filter, while all-wheel-drive models hold about 5.3 quarts. The Malibu, which wrapped up production with the 2025 model year, uses Dexos1-approved 5W-30 in its 1.5L turbo engine.
The table below summarizes specifications for current Chevrolet engines. Capacities include the oil filter, and older model years may differ.

Why Does Using the Right Oil Matter?
The right oil keeps your engine protected, efficient, and running the way Chevrolet engineered it to. Modern turbocharged and direct-injected engines have tight tolerances, and the wrong viscosity or an unapproved oil may not hold up as well.
That’s where Dexos1-approved oil comes in. Dexos is GM’s own oil specification, and approved oils are tested for deposit control, wear protection, and resistance to breakdown beyond basic industry standards. Look for the Dexos1 trademark on the bottle.
Viscosity matters too. In 0W-20, the “0W” means the oil flows easily at cold start-up, and the “20” indicates its viscosity at operating temperature. A quality 0W-20 full synthetic oil reaches critical engine parts quickly at startup, when much of an engine’s wear happens, and resists thinning out in summer heat. That’s useful in East Tennessee, where drivers deal with humid summers, the occasional winter cold snap, hilly back roads, and stop-and-go traffic on I-40.
Can I Use Conventional Oil in My Chevy?
For most modern Chevrolets, conventional oil isn’t the right choice. If your owner’s manual calls for a Dexos1-approved oil, that’s what your engine should get, and conventional oils generally don’t carry that approval.
So, can I use conventional oil in my Chevy in a pinch? If your oil is low and approved oil isn’t available, adding oil of the correct viscosity is better than driving with too little. Just switch back to the specified oil at your next change. GM also notes that engine damage caused by oil that doesn’t meet its specification may not be covered under warranty, so sticking with the right oil protects your investment as well as your engine.
How Often Should You Change Your Chevy’s Oil?
Your Chevrolet will tell you. Most models use GM’s Oil Life Monitoring System, which tracks engine revolutions, operating temperature, and driving conditions to determine when an oil change is due.
That means your Chevy oil change interval isn’t one fixed number. Towing, short trips, extended idling, and hot weather all wear oil down faster, and the system adjusts accordingly. Check the oil life percentage in your Driver Information Center, and schedule service when you see a change-oil message. Even if you don’t drive much, change the oil at least once a year, and check the dipstick between visits.
Choosing the Right Oil for Your Chevrolet
Choosing the right oil comes down to knowing your engine. Most Chevys take Dexos1-approved 0W-20, but certain trucks, the Blazer V6, and diesel models have different needs. If you’re unsure, Beaty Chevrolet can look up the correct specification for your vehicle and handle your next Chevy oil change in Knoxville with the right oil and filter.

How often should I change the oil in my Chevrolet?
Follow your Oil Life Monitoring System and change the oil when the Driver Information Center prompts you. Change it at least once a year even if the system hasn't triggered.

It's not recommended for engines that require Dexos-approved oil. Conventional oil generally doesn't carry Dexos approval, so use the specified oil whenever possible.
