Engine maintenance is a key factor in the performance and the life span of any vehicle. One of the most important things to carry out as far as the maintenance is concerned is to change the oil of your car on a regular basis. Learning the method of changing oil in a vehicle is not only economical but, it also makes your engine run effectively. The guide will take a professional step-by-step process, and some of the necessary steps that will be taken include changing the oil filter and checking the oil pressure sensor.
The Importance of Regular Oil Changes
The function of the engine oil is to lubricate moving parts, reduce friction and prevents overheating. Oil over time decays and contains pollutants which make it ineffective. The consequences of neglecting to carry out the oil changes on time may include:
Reduced engine performance
Decreased fuel efficiency
Overheating and engine wear
Expensive repairs or engine failure
Regular oil changes protect your engine, extend its lifespan, and improve overall vehicle performance.
Tools and Materials Required
Before starting, ensure you have the following tools and materials:
Correct engine oil (refer to your vehicle manual for type and quantity)
New oil filter
Oil filter wrench
Socket wrench or spanner
Oil drain pan
Funnel
Gloves and absorbent rags
Vehicle jack and stands (if necessary for clearance)
Step 1: Vehicle Preparation
Park your vehicle on a flat, stable surface.
Engage the parking brake and switch off the engine.
Allow the engine to cool for at least 10–15 minutes to avoid burns.
Step 2: Draining the Old Oil
Position the oil drain pan beneath the oil pan.
Using a socket wrench, carefully remove the drain plug.
Allow all old oil to drain completely.
Reinstall and securely tighten the drain plug to prevent leaks.
Professional Tip: Use gloves to maintain cleanliness and safety while handling used oil.
Step 3: Replacing the Oil Filter
Replacing the oil filter is critical for maintaining oil quality and engine protection. Follow these steps to understand how to change oil filter effectively:
Locate the oil filter beneath the engine.
Use the oil filter wrench to remove the old filter carefully.
Apply a small amount of fresh oil to the rubber gasket of the new filter.
Install the new filter by hand, ensuring it is snug but not overtightened.
Note: The oil filter should be replaced with every oil change to ensure optimal engine performance.
Step 4: Adding Fresh Oil
Remove the oil fill cap located on the engine.
Using a funnel, pour the recommended engine oil into the engine.
Replace the oil cap securely after filling.
Step 5: Checking Oil Level and Oil Pressure Sensor
Start the engine and let it run for a few minutes to circulate the new oil.
Turn off the engine and wait several minutes, then check the oil level using the dipstick.
Ensure the oil level is within the recommended range.
Verify the oil pressure sensor is functioning correctly. Understanding how to change oil pressure sensor ensures accurate oil readings and prevents potential engine damage.
Pro Tip: Low oil pressure readings could indicate insufficient oil or a faulty sensor.
Step 6: Clean-Up and Responsible Disposal
Wipe away any oil spills around the engine and drain area.
Transport used oil and filters to an authorized recycling center or automotive store for proper disposal.
Environmental Advisory: Never dispose of used oil in drains or on the ground—it is hazardous to the environment.
Best Practices for Oil Maintenance
Always use oil recommended in your vehicle’s manual.
Avoid overfilling, as it can cause leaks and engine issues.
Regularly monitor oil levels between scheduled changes.
Document the oil change process for reference.
Replace the oil filter every oil change to maintain engine health.
Frequently Asked Questions
Q1: How often should oil be changed in a car?
Most vehicles require oil changes every 3,000–5,000 miles for conventional oil and 7,500–10,000 miles for synthetic oil. Always follow your vehicle manufacturer’s guidelines.
Q2: Can I perform an oil change myself?
Yes. With proper tools, safety precautions, and adherence to steps, changing oil at home is straightforward and cost-effective.
Q3: How do I know if the oil pressure sensor is faulty?
Persistent oil warning lights despite adequate oil levels may indicate a malfunctioning sensor requiring replacement.
Conclusion
How to change oil in the car is a necessary skill everyone who has a car should have. With this professional step by step guide, such as changing oil filters and checking oil pressure sensors, you will be guaranteed that your engine is healthy, efficient and reliable. Timely maintenance of oil is also a way of protecting your car as well as maximizing its performance and lifespan.
