I’m looking for some clarity on the recommended oil change intervals for GM vehicles, particularly for my Chevrolet. It seems like every source I check gives me different advice, and I want to ensure I’m doing it right to keep my engine running smoothly.
Why Oil Change Intervals Matter
Regular oil changes are critical for maintaining engine efficiency and prolonging the life of your vehicle. Fresh oil lubricates engine components and helps in reducing wear, improving performance, and increasing fuel efficiency. But how often should we be doing this for our Chevys?
GM’s Recommended Guidelines
From what I’ve gathered, GM generally recommends changing the oil every 7,500 miles or once a year, whichever comes first, for vehicles with synthetic oil. However, certain driving conditions may require more frequent changes:
Severe Driving Conditions: If you often drive in stop-and-go traffic, haul heavy loads, or drive on rough or dusty roads, you might want to consider changing oil more frequently—every 5,000 miles.
Short Trips: If most of your driving is short trips (less than 10 miles), you might also be looking at shorter intervals.
What Oil Should I Use?
While I’m at it, what’s the best oil for my specific model? I hear a lot about synthetic vs. conventional oil. What is best based on your experience? Are there certain brands you could recommend?
Maintenance Best Practices
Additionally, does anyone have best practices for maintaining oil levels or monitoring oil quality between changes? Should I be looking for anything specific when checking the oil?
I’m eager to hear your experiences and insights. Let’s help each other out and make sure we’re keeping our cars in the best shape possible! What’s your routine when it comes to oil changes?
The general recommendation for most Chevrolet vehicles is to change your oil every 7,500 miles if you’re using synthetic oil. However, it can be as short as 3,000 miles for models with older engines.
That’s a good rule of thumb! I have a 2020 Chevy Silverado, and I follow the 7,500 miles interval with synthetic oil too. Seems to keep the engine running smoothly.
For older models, like the pre-2010 ones, I’ve heard it’s better to change oil every 3,000 miles, especially if not using synthetic. Anyone else follow this advice?

Absolutely! If you’re doing a lot of stop-and-go driving in the city, you might want to change your oil more frequently than if you’re mostly cruising on the highway.
Don’t forget about towing! If you’re regularly hauling stuff, it’s usually best to reduce the interval to 3,000-5,000 miles, as the engine works harder.
Exactly! Plus, extreme weather conditions can also be tough on your oil. Hot summers or freezing winters can change how often you should be getting those changes.
