How to Know When It’s Time for an Oil Change (It’s Not Just the Sticker)

We’ve all seen it — that little reminder sticker in the corner of your windshield. But the truth is, your engine might be asking for an oil change before or after that date depending on how you drive.
Knowing the real signs can help protect your engine, improve performance, and even extend the life of your vehicle.
The Purpose of Oil — and Why It Matters
Engine oil keeps things running smoothly. It lubricates internal components, helps prevent overheating, and carries away contaminants.
But over time, oil breaks down and collects dirt, reducing its effectiveness. Ignoring oil changes can lead to lower performance, poor fuel economy, and costly repairs.
Top Signs It’s Time for an Oil Change
1. The Oil Looks Dirty Fresh oil is amber-colored and smooth. If yours is dark, gritty, or sludgy, it’s time for a change — no matter what the sticker says.
2. Engine Is Louder Than Usual Oil cushions moving engine parts. If your engine sounds louder or rougher, the oil may not be doing its job.
3. You Smell Oil or Exhaust in the Cabin A strong smell of oil or burning could mean a leak — or that your oil is so old it’s breaking down.
4. The Oil Light Is On If the oil pressure warning light is illuminated, stop and check your oil level right away. Driving like this can cause major engine damage.
5. It’s Been a While — or You’ve Driven Hard Modern vehicles can often go 5,000–7,500 miles (or more) between changes. But if you’ve been towing, idling in traffic, or driving in Texas heat, your oil may wear out faster.
It’s About More Than Mileage
While mileage is a useful guideline, your driving conditions, vehicle age, and engine type all affect how quickly oil breaks down. If in doubt, let us take a look.
