An automotive oil change service is one of the most essential maintenance tasks for a vehicle. It involves draining the old engine oil and replacing it with fresh oil, along with changing the oil filter. This service is crucial for keeping the engine running smoothly, improving its longevity, and maintaining optimal performance.

​

Why Oil Changes Are Important:

Engine oil plays several critical roles:

• Lubrication: Oil lubricates the moving parts of the engine, reducing friction and wear.

• Cooling: It helps dissipate heat generated by the engine’s moving components, preventing overheating.

• Cleaning: Oil carries away dirt, debris, and contaminants that accumulate in the engine.

• Corrosion Prevention: Additives in engine oil help prevent rust and corrosion inside the engine.

• Sealing: Oil helps form a seal between pistons, rings, and cylinder walls, improving engine efficiency.

 

Over time, engine oil degrades, loses its effectiveness, and becomes contaminated with dirt, debris, and combustion byproducts. Changing the oil regularly is necessary to maintain engine health and performance.

 

Steps Involved in an Automotive Oil Change Service:

1. Preparation:

   • The technician will start by raising the vehicle using a lift or jack stands to access the oil drain plug and filter. This step ensures safety and gives the technician a clear workspace.

   • They will also check the vehicle’s oil specifications to determine the correct type and grade of oil required (conventional, synthetic, or blend) based on the vehicle’s manufacturer recommendations.

2. Draining the Old Oil:

   • Drain Plug Removal: The oil drain plug is removed, and the old oil is drained into a pan. This step allows the technician to remove all the used oil from the engine.

   • Time to Drain: It typically takes a few minutes for all the oil to drain out. The technician will ensure that the oil is completely emptied from the engine before moving to the next step.

3. Oil Filter Replacement:

   • The oil filter is unscrewed and replaced with a new one. The filter traps dirt and contaminants from the oil, preventing them from circulating in the engine.

   • Lubricating the Filter Gasket: Before installing the new filter, the technician will apply a small amount of fresh oil to the gasket of the filter to ensure a proper seal and to prevent leaks.

4. Installing the Drain Plug:

   • After the old oil has fully drained, the drain plug is cleaned and reinstalled securely. It’s essential that the drain plug is tightened to the correct torque specification to prevent leaks but avoid over-tightening, which can strip the threads.

5. Refilling the Engine with New Oil:

   • The engine is refilled with the appropriate amount and type of oil, as specified in the vehicle’s manual. The technician will use a funnel to prevent spills and pour the new oil into the engine via the oil fill cap.

   • Types of Oil:

     • Conventional Oil: Standard oil used in older vehicles or less demanding driving conditions.

     • Synthetic Oil: Designed for higher performance, synthetic oil lasts longer and provides better protection, especially in extreme temperatures.

     • Synthetic Blend: A mix of conventional and synthetic oil, offering better protection than conventional but at a lower cost than full synthetic.

6. Checking the Oil Level:

   • Once the oil has been added, the technician will check the oil level using the dipstick to ensure the engine has the correct amount of oil. If necessary, they will add more oil to reach the proper level.

7. Inspection for Leaks:

   • After refilling, the technician will inspect the vehicle’s underside to ensure that no oil is leaking from the drain plug or filter. If there are leaks, they will adjust or replace any components as needed.

8. Running the Engine:

   • The technician will start the vehicle and let it run for a few minutes. This allows the new oil to circulate throughout the engine and ensures that the oil pressure is normal.

   • During this step, they will also check for any abnormal noises or dashboard warning lights, which could indicate a problem.

9. Final Oil Level Check:

   • After the engine is turned off, the technician will allow a few minutes for the oil to settle and then perform a final check of the oil level. If needed, more oil will be added to ensure the level is at the proper mark.

10. Resetting the Oil Change Indicator:

    • Many modern vehicles are equipped with an oil life monitor or oil change indicator. The technician will reset this system to notify the vehicle’s computer that the oil change has been completed.

 

Additional Services During an Oil Change:

During a standard oil change, many service centers also perform additional checks on the vehicle, which may include:

• Fluid Level Check: Inspecting and topping off fluids such as transmission fluid, brake fluid, power steering fluid, and windshield washer fluid.

• Tire Pressure Check: Ensuring tires are properly inflated for safe driving and fuel efficiency.

• Visual Inspection: Checking belts, hoses, air filters, and other key components to ensure they are in good condition.

• Wiper Blade Check: Inspecting windshield wipers and replacing them if necessary.

• Chassis Lubrication: Some older vehicles with grease fittings may require lubrication of suspension and steering components.

 

Signs That Your Vehicle Needs an Oil Change:

• Dashboard Warning Light: Most modern vehicles have an oil pressure or oil change indicator light that will illuminate when it’s time for a change.

• Dirty or Dark Oil: Fresh oil is amber and transparent. Over time, it darkens and becomes dirty, signaling the need for replacement.

• Excessive Engine Noise: If the oil is old or low, you might hear increased engine noise or knocking due to insufficient lubrication.

• Burning Oil Smell: An oil leak or low oil level can cause a burning smell as oil comes into contact with hot engine parts.

• Decreased Fuel Efficiency: Poor oil condition can cause the engine to work harder, reducing overall fuel efficiency.

 

How Often Should You Change Your Oil?

• Conventional Oil: Typically every 3,000 to 5,000 miles or 3 to 6 months.

• Synthetic Oil: Every 7,500 to 10,000 miles or 6 to 12 months.

• Check the Owner’s Manual: Always refer to the manufacturer’s recommendations in the vehicle’s manual for the most accurate intervals.

 

Benefits of Regular Oil Changes:

1. Improved Engine Performance:

   • Fresh oil ensures that engine parts are properly lubricated, reducing friction and wear, which improves overall engine performance.

2. Prolonged Engine Life:

   • Regular oil changes help to remove dirt, debris, and metal particles that accumulate in the engine, reducing wear and prolonging the engine’s lifespan.

3. Better Fuel Efficiency:

   • Clean oil helps the engine run smoothly and more efficiently, reducing fuel consumption and improving gas mileage.

4. Reduced Engine Wear and Tear:

   • Regular oil changes prevent the buildup of sludge and deposits, which can damage engine parts and lead to costly repairs.

5. Cooling the Engine:

   • Oil helps to keep engine components cool by reducing friction and absorbing heat, preventing overheating.

​

An automotive oil change service is a vital part of vehicle maintenance that involves draining old oil, replacing the oil filter, and refilling the engine with fresh oil. Regular oil changes are necessary to maintain engine performance, reduce wear and tear, and extend the life of the vehicle. By following the recommended service intervals and using the appropriate type of oil, drivers can ensure their engines remain in top condition and avoid costly repairs down the road.
