Regular oil changes are one of the most important things you can do to keep your car running smoothly. But with so much conflicting advice out there—change it every 3,000 miles! No, wait, every 10,000!—it's hard to know what's right for your vehicle.
Let's cut through the noise.
How Often Should You Change Your Oil?
The "3,000 mile rule" is outdated. Modern engines and oils have come a long way. Here's what actually matters:
📋 The Simple Answer
- Conventional oil: Every 5,000-7,500 miles
- Synthetic oil: Every 7,500-15,000 miles
- Your owner's manual: The final word for your specific vehicle
Your driving habits also matter. If you do a lot of short trips, stop-and-go driving, towing, or driving in extreme temperatures, you may need more frequent changes.
Synthetic vs Conventional: Which Is Better?
🔵 Conventional Oil
- Cost: $30-75 per change
- Change every 5,000-7,500 miles
- Good for older vehicles
- Works well in moderate climates
🟢 Synthetic Oil
- Cost: $65-125 per change
- Change every 7,500-15,000 miles
- Better engine protection
- Performs in extreme temps
While synthetic costs more per change, you need fewer changes—so the total cost can be similar. Synthetic also provides better protection, especially if you want your engine to last 200,000+ miles.
Warning Signs You Need an Oil Change
Don't wait until something breaks. Watch for these signs:
- Dark, dirty oil: Check your dipstick. Fresh oil is amber; old oil is dark brown or black.
- Engine noise: Oil lubricates moving parts. Without it, you'll hear more knocking or rumbling.
- Oil change light: Your car's computer is telling you it's time.
- Exhaust smoke: Blue or gray smoke means oil may be burning in the engine.
- Low oil level: If you're frequently adding oil between changes, there may be an issue.
How Much Does an Oil Change Cost?
Prices vary by location, vehicle, and oil type:
- Conventional: $30-75
- Synthetic blend: $45-90
- Full synthetic: $65-125
- High-mileage: $50-100 (for 75,000+ mile vehicles)

What's Included in an Oil Change?
A standard oil change typically includes:
- Draining the old oil
- Replacing the oil filter
- Adding new oil (type specified for your vehicle)
- Checking fluid levels
- Resetting the oil life monitor (if applicable)
Some shops also do a quick multi-point inspection, checking things like tire pressure, lights, and wiper fluid at no extra charge.
Can I Do It Myself?
If you're handy, yes! A DIY oil change costs $25-50 for materials (oil + filter). You'll need:
- The right oil (check your manual for type and quantity)
- A new oil filter
- A drain pan
- A wrench for the drain plug
- A filter wrench
But if you value your time or don't want to deal with disposal, booking a professional oil change is easy and affordable.
