Engine oil lubricates moving parts, reduces friction, and helps dissipate heat. It also cleans engine components by carrying away contaminants. Regular oil changes ensure these functions are maintained, promoting engine longevity.
What Happens When You Skip Oil Changes
Neglecting oil changes can lead to sludge buildup, increased friction, and overheating. Over time, this can cause significant engine damage, leading to costly repairs or even engine failure.
Different Types of Engine Oil and Their Uses
Conventional vs. Synthetic vs. Synthetic Blend Oil
Conventional Oil: Derived from crude oil, suitable for light-duty vehicles with simple engine designs.
Synthetic Oil: Chemically engineered for high performance, offering better protection and longer intervals between changes.
Synthetic Blend: A mix of conventional and synthetic oils, providing a balance between cost and performance.
Choosing the Right Oil for Your Vehicle
Consult your owner’s manual to determine the recommended oil type and viscosity. Factors like driving habits, climate, and vehicle age can influence the best choice for your car.
How Often Should You Change Your Oil?
Manufacturer Recommendations vs. Traditional Advice
While the old rule was every 3,000 miles, modern engines and oils have extended intervals. Many manufacturers now recommend oil changes every 5,000 to 7,500 miles for conventional oil and up to 10,000 miles for synthetic oil.
Key Factors That Affect Oil Change Frequency
Driving Conditions: Frequent short trips, stop-and-go traffic, or extreme temperatures can necessitate more frequent oil changes.
Vehicle Age: Older engines may require more frequent oil changes due to increased wear.
Oil Type: Synthetic oils generally last longer than conventional oils.
