🪜 Step-by-Step Guide to Changing Engine Oil
Step 1: Prepare Your Car
Park your car on a flat surface and let the engine cool down.
👉 Real-world tip:
From my experience, many beginners make the mistake of working on a slightly sloped surface. This can cause incorrect oil drainage and even safety issues. Always work on level ground.
Step 2: Drain Old Oil
When I first started as a technician, I rushed an oil drain and ended up with hot oil running down my arm not fun. Always let the engine cool slightly, then remove the drain plug slowly. Give it 10–15 minutes to fully drain you’d be surprised how much old oil stays behind if you rush it.
Place a drain pan under the oil plug and carefully remove it.
👉 Real-world tip:
If the engine is still warm, the oil will drain faster—but don’t do this when it’s too hot. I’ve seen beginners rush this step and end up with minor burns or messy spills.
Step 3: Replace Oil Filter
Remove the old oil filter and install a new one.
👉 Real-world tip:
A common mistake is over-tightening the new filter. Hand-tight is enough. Over-tightening can damage the seal and make it extremely difficult to remove next time.
Step 4: Add New Engine Oil
Overfilling oil is one of the most common mistakes I fix in the workshop. A customer once added “just a bit extra” and ended up with foaming oil and rough idling. Always check the dipstick after filling don’t guess. Engines are precise, not forgiving.
Use a funnel and pour in the recommended oil type.
👉 Real-world tip:
Don’t pour the full amount at once. Add gradually and check the level. Overfilling is a very common issue I see in workshops.
Step 5: Check Oil Level
Use the dipstick to confirm the oil level is correct.
👉 Real-world tip:
Always wait a couple of minutes after adding oil before checking. This allows the oil to settle properly and gives an accurate reading.
❌ Common Mistakes to Avoid
I’ve seen too many DIY jobs go wrong just because someone relied only on a jack. One customer came in with a bent sump after the car slipped. Always use jack stands on a flat surface it’s not optional. Trust me, a 5-minute shortcut can cost you an engine
- Overfilling the oil
- Forgetting to replace the oil filter

🌱 How to Dispose of Used Oil Properly

Instead:
- Store it in a sealed container
- Take it to a local recycling center or auto shop
