Introduction
Your car’s engine is like its heart — and engine oil is the lifeblood that keeps it running smoothly. Oil lubricates moving parts, reduces heat, and helps remove dirt and debris. But over time, oil breaks down and becomes less effective. That’s why regular oil changes are crucial to keeping your vehicle in top shape.In this guide, we’ll walk you through when to change your engine oil and how to do it properly.
When to Change Your Engine Oil
Follow the Manufacturer’s Recommendation
Most cars today can go 5,000 to 10,000 miles (8,000 to 16,000 km) between oil changes, depending on:The type of oil used (conventional vs. synthetic)
Your driving conditions
The engine design
Check your owner’s manual for the exact interval. It’s your most reliable source.
Look for Warning Signs
Even if you’re following the schedule, watch for these signs that your oil may need changing:
The oil change light or check engine light comes on
The oil looks dirty or gritty
The engine is noisier than usual
You notice poor fuel economy
You detect a burning oil smell
Consider Your Driving Habits
If you:
Drive in extreme heat or cold
Frequently drive short distances
Sit in stop-and-go traffic often
Tow heavy loads
you might need to change your oil more often than the manual recommends.

Funnel,Drain pan,Gloves & rags,Jack and jack stands (or ramps)
Oil filter gasket (optional)

Run your engine for 2–3 minutes. Warm oil drains faster and more completely.
Step 2: Park and Secure the Car

Apply the parking brake
Use a jack and jack stands or drive up on ramps
Step 3: Drain the Old Oil
Place the drain pan under the oil pan
Remove the drain plug with a wrench
Let the oil drain completely (wait 5–10 minutes)
Clean and reinsert the drain plug, tightening it securely (but not overly tight)
Step 4: Replace the Oil Filter
Use the filter wrench to unscrew the old filter
Make sure the old gasket comes off with it
Rub a little new oil on the new filter’s gasket
Screw on the new filter by hand (firm, but not over-tightened)

Quick Tips and Common Mistakes
Always use the right oil grade (check the owner’s manual).
Never overtighten the oil filter or drain plug — it can strip threads.
Check for leaks after changing the oil.
Record your oil change date/mileage to stay on schedule.
Synthetic vs. Conventional Oil
| Feature | Conventional Oil | Synthetic Oil |
| Cost | Cheaper | More expensive |
| Lifespan | 3,000–5,000 miles | 7,500–10,000+ miles |
