Engine oil is one of the most important fluids in your vehicle. It lubricates the engine’s moving parts, reduces friction, helps control temperature, and keeps the engine running smoothly. However, engine oil becomes less effective over time, which is why regular oil changes are essential.

Why Is Engine Oil Important?

Inside your engine, hundreds of moving parts work together at high temperatures and speeds. Without proper lubrication, these components can experience excessive friction and wear.

Fresh engine oil helps:

• Lubricate moving engine components
• Reduce friction and engine wear
• Keep the engine running smoothly
• Help control engine temperature
• Remove dirt and small contaminants
• Improve overall engine performance

How Often Should You Change Your Oil?

The recommended oil-change interval depends on your vehicle, engine type, oil type, and driving conditions. Many modern vehicles can go longer between oil changes than older vehicles.

However, you should always follow the manufacturer's recommended maintenance schedule.

If you frequently drive in hot weather, heavy traffic, dusty conditions, or stop-and-go traffic, your engine may require more frequent oil changes.

Signs Your Car May Need an Oil Change

Watch for signs such as:

• Dark or dirty-looking engine oil
• An oil warning light on the dashboard
• Unusual engine noises
• Reduced engine performance
• Poor fuel economy
• An engine that runs hotter than normal
• A burning-oil smell

Ignoring these signs can allow engine problems to develop into expensive repairs.

Don't Forget the Oil Filter

Whenever you change your engine oil, it is also important to check or replace the oil filter according to your vehicle manufacturer's recommendations. A clean filter helps prevent contaminants from circulating through the engine.
