What is an Oil Change and How Does It Work?
An oil change is the process of replacing your vehicle’s engine oil and oil filter to maintain proper lubrication, reduce friction, and remove contaminants. Engine oil is essential for protecting internal components from wear, dissipating heat, and keeping your engine running smoothly.
During an oil change, the old, dirty oil is drained, the oil filter is replaced, and fresh oil—chosen for your engine’s specifications—is added.
Why Oil Changes Matter
Over time, engine oil degrades and collects dirt, metal particles, and other contaminants. Failing to change your oil regularly can lead to increased engine wear, overheating, reduced fuel efficiency, and potential engine damage.
Routine oil changes extend the life of your engine, improve performance, and help maintain your vehicle’s warranty compliance.
Important to Know:
- Oil change intervals depend on your vehicle, driving conditions, and type of oil (conventional, synthetic blend, or full synthetic).
- Always use the oil grade recommended by the manufacturer for optimal performance.
- Replacing the oil filter is crucial to ensure contaminants are removed from the engine.
How an Oil Change is Done:
- Warm up the engine slightly to allow oil to drain smoothly.
- Raise the vehicle and safely remove the drain plug to drain old oil.
- Replace the oil filter with a new OEM or high-quality filter.
- Refill the engine with the correct type and amount of oil.
- Check for leaks and proper oil level.
- Reset maintenance reminder or service light.
- Test drive briefly to ensure smooth operation.
When to Change Your Oil:
- Conventional oil: every 3,000–5,000 miles
- Synthetic blend: every 5,000–7,500 miles
- Full synthetic: every 7,500–10,000 miles
(Always follow manufacturer recommendations and driving conditions.)
Signs You May Need an Oil Change:
- Dark or dirty oil on the dipstick
- Engine noise or knocking due to poor lubrication
- Oil change or maintenance light illuminated
- Reduced fuel efficiency
- Excessive engine heat
