Introduction: Oil Changes Aren’t Optional—They’re Essential
If there's one service every Chevrolet owner should prioritize, it's the oil change. It might not feel urgent, especially if your vehicle runs fine, but clean engine oil is critical to long-term performance and reliability. The difference between staying on schedule and pushing it “just a little longer” can be the difference between a smooth-running engine and costly repairs.
At Chevrolet GMC of Corsicana, we perform oil changes every day for drivers who want to protect their investment. Whether you drive a Silverado 1500, Equinox, Malibu, or Trailblazer, this guide will walk you through how often your Chevrolet needs an oil change, what factors impact timing, and how to know when it’s time to schedule service.
How Often Should You Change Your Chevrolet’s Oil?
The short answer: It depends.
General guidelines for modern Chevrolets:
-
Synthetic oil (used in most newer Chevrolets): Typically every 7,500 to 10,000 miles
-
Conventional oil (used in older models): Every 3,000 to 5,000 miles
That said, always defer to your owner’s manual for the exact service interval. Chevrolet uses Oil Life Monitoring Systems (OLMS) in most vehicles built after 2010, which monitor your driving habits and engine conditions to give you a personalized oil change interval.
If you see a dashboard message like “Change Engine Oil Soon”, don’t ignore it. That alert is based on real-time data and signals that it’s time for service.
What Affects Oil Change Frequency?
Your vehicle and oil type are only part of the equation. Several driving and environmental factors can shorten the lifespan of your engine oil:
1. Driving Conditions
-
Stop-and-go traffic
-
Short trips under five miles
-
Frequent idling
-
Towing or hauling heavy loads
These put more strain on your engine and reduce the oil’s effectiveness more quickly.
2. Climate and Temperature
Extremely hot Texas summers or cold winters can affect oil viscosity and performance. If you’re regularly driving in high-heat conditions, you may need oil changes closer to the low end of the mileage range.
3. Vehicle Age
Older engines may burn oil more quickly or accumulate sludge faster, requiring more frequent changes—even if you’re not driving far.
Why Chevrolet Oil Changes Matter
Skipping oil changes doesn’t just put off a routine task—it increases long-term wear and the risk of engine failure. Here’s why fresh oil is so essential:
-
Lubrication: Reduces friction between engine parts, preventing overheating
-
Cooling: Helps regulate engine temperature
-
Cleaning: Picks up dirt, debris, and microscopic metal particles
-
Efficiency: Clean oil supports better fuel economy and smoother performance
Neglecting oil service leads to sludge buildup, decreased fuel efficiency, and eventually, costly damage to pistons, cylinders, and other critical components.

Even if your dashboard isn’t flashing a warning, your car may be showing signs that it’s ready for service:
-
Engine sounds louder than usual
-
Oil looks dark or gritty on the dipstick
-
Exhaust smoke is darker or more noticeable
-
Noticeable drop in fuel efficiency
-
Dashboard alert: “Change Engine Oil Soon” or check engine light
Don’t second-guess it. If something feels off, getting ahead of the issue’s always safer (and cheaper).

What Type of Oil Does Chevrolet Use?
Chevrolet vehicles are generally filled with dexos1 Gen 3-certified synthetic oil, a high-performance standard developed by General Motors for better fuel economy, protection, and longevity.
Common oil types used in Chevrolet models:
-
0W-20 or 5W-30 synthetic oil – Most newer Chevy cars and crossovers
-
5W-30 or 10W-30 conventional/synthetic blend – Some older models
-
Diesel oil – For models like the Silverado HD with Duramax engines
What does your vehicle take? Our technicians will always use GM-approved oil based on your model and mileage. If you'd like to extend your service intervals, you can also ask about synthetic upgrades.
