How to Change Engine Oil the Right Way – Mechanic Level Guide
Introduction:
Hello friends, welcome to Rajesh Technical Blog! Today, I’m going to share a complete guide on
how to change engine oil the right way. Whether you are a beginner or an
aspiring mechanic, following the proper steps ensures your engine stays healthy and your vehicle runs smoothly. Changing engine oil might seem simple, but doing it incorrectly can harm your engine over time. So, let’s dive into the step-by-step -level guide.
Why Changing Engine Oil is Important
Engine oil is like the lifeblood of your vehicle. It lubricates all the moving parts, reduces friction, cools the engine, and prevents wear and tear. Over time, oil loses its viscosity and becomes contaminated with dust, dirt, and metal particles. Running your engine with old oil can cause:
- Increased friction and heat
- Poor engine performance
- Reduced fuel efficiency
- Premature engine wear
- Risk of engine failure
By changing your engine oil regularly, you ensure your vehicle performs at its best and lasts longer.
Tools and Materials You Will Need
Before starting, gather the following tools and materials:
- New Engine Oil – Check your vehicle’s manual for the correct type and quantity.
- Oil Filter – It’s recommended to change the filter with every oil change.
- Oil Drain Pan – To collect old oil safely.
- Wrench/Socket Set – To remove the drain plug.
- Oil Filter Wrench – To remove the old filter easily.
- Funnel – For pouring new oil without spills.
- Gloves and Rags – To keep hands clean and wipe spills.
- Jack and Jack Stands (if needed) – To lift the vehicle safely.
Step 1: Prepare Your Vehicle
- Park your vehicle on a flat, stable surface.
- Engage the parking brake.
- Allow the engine to cool slightly if it’s hot. Warm oil flows faster, but hot oil can burn you.
- Place jack stands if necessary to access the drain plug easily.
Step 2: Drain the Old Engine Oil
- Place the oil drain pan beneath the oil drain plug.
- Use the wrench to carefully remove the drain plug.
- Let the old oil flow completely into the pan.
- Inspect the drain plug for metal shavings or debris. If there are any, consult a mechanic as it could indicate engine issues.
- Once drained, clean the drain plug and re-install it securely. Do not overtighten as it can strip the threads.
Step 3: Replace the Oil Filter
- Locate the oil filter. It may be on the side or bottom of the engine.
- Use the oil filter wrench to remove the old filter. Expect some oil to spill, so keep your drain pan beneath it.
- Before installing the new filter, lubricate the rubber gasket with a little new engine oil.
- Screw the new filter in place by hand. Do not overtighten; hand-tight is usually enough.
Step 4: Add New Engine Oil
- Open the engine oil cap on top of the engine.
- Use a funnel to pour in the correct amount and type of new engine oil.
- Replace the oil cap securely.
- Start the engine and let it run for a few minutes. Check for leaks around the drain plug and oil filter.
- Turn off the engine, wait a few minutes, then check the oil level using the dipstick. Add oil if necessary to reach the recommended level.
Step 5: Dispose of Old Oil Properly
Used engine oil is hazardous to the environment. Pour it into a sealed container and take it to a recycling center or authorized service station. Never dump it on the ground or in drains.
Tips for a Professional Oil Change
- Always use oil recommended by the vehicle manufacturer.
- Change oil every 3,000–5,000 miles (or as recommended for your engine type).
- Check the oil level monthly to avoid engine damage.
- Keep a maintenance log for all oil changes and servicing.
- Inspect the vehicle for leaks, unusual noises, or engine performance issues.
Common Mistakes to Avoid
- Overfilling or underfilling oil – Can cause engine damage or poor lubrication.
- Not replacing the oil filter – Can reduce the efficiency of the new oil.
- Improper disposal of old oil – Harmful to the environment.
- Using the wrong oil type – Can affect engine performance and warranty.
- Loose drain plug or filter – Can cause oil leaks and engine damage.
Conclusion
Changing engine oil is a simple yet vital maintenance task that can save your engine from premature wear and expensive repairs. Following these mechanic-level steps ensures your vehicle runs efficiently and safely. Remember, regular oil changes are not just about performance—they are about protecting your investment and ensuring your ride lasts longer.2025/11/10-most-common-bike-problems-and-their
