How to Check Oil Levels Without Making Mistakes

Checking your car’s engine oil is one of the simplest but most crucial maintenance tasks you can do. Oil keeps your engine lubricated, reduces friction, prevents overheating, and protects against wear and tear. Yet many drivers either neglect it or make mistakes that can lead to inaccurate readings, engine damage, or costly repairs.

Whether you’re a first-time car owner or have been driving for years, knowing how to check your oil correctly is a skill that pays off. Here’s a step-by-step guide to help you check your oil levels safely and accurately, along with tips to avoid common errors.

Why Checking Oil Levels Matters

Engine oil isn’t just a lubricant — it’s the lifeblood of your engine. Running on low or dirty oil can cause:

• Engine overheating
• Excessive wear on moving parts
• Poor fuel efficiency
• Expensive repairs or even engine failure

Regularly checking your oil ensures your engine stays healthy, reduces breakdown risks, and extends your car’s lifespan. In Australia, where temperatures can vary from scorching summer heat to chilly winter mornings, maintaining the right oil level is essential.

What You’ll Need to Check Oil Properly

Before you start, gather the following:

• A clean rag or paper towel
• Gloves (optional, to avoid getting oil on your hands)
• The owner’s manual (for reference)

Having the right tools ensures you get an accurate reading and stay safe while working under the hood.

Step 1: Park on a Level Surface

Oil settles at the lowest point of the engine, so always check oil on a flat, level surface.

• Parking on a slope can give a false reading, making it seem like the oil level is higher or lower than it actually is.
• Turn off the engine and let it sit for 5–10 minutes to allow oil to drain back into the oil pan.

Checking oil immediately after driving can result in inaccurate readings and expose you to hot engine parts.

Step 2: Locate the Dipstick

Most cars have a dipstick marked with a bright-coloured handle (yellow or orange) under the hood. Consult your owner’s manual if you’re unsure.

• Pull the dipstick out slowly.
• Wipe it clean with a rag or paper towel to remove any oil residue.

This first wipe ensures that the oil level you read isn’t distorted by old, clinging oil.

Step 3: Reinsert and Remove the Dipstick

Once clean:

• Fully insert the dipstick back into its tube.
• Wait a few seconds, then pull it out again carefully.
• Hold it horizontally and check the oil level against the marked indicators (usually “MIN” and “MAX” or two dots/lines).

Tip: Always check the level at eye height to get an accurate reading. Reading from an angle can mislead you.

Step 4: Interpret the Oil Level

Oil should sit between the minimum and maximum marks.

• If it’s below the minimum, you need to top up immediately.
• If it’s above the maximum, you may have overfilled — this can also damage the engine.
• If the oil looks dark or dirty, consider an oil change even if the level is fine.

Healthy engine oil should have a light amber colour (darkening over time is normal, but very black oil indicates it’s time for a change).

Step 5: Top Up Correctly (If Needed)

If you need to add oil:

1. Check your owner’s manual for the correct oil type and viscosity. Using the wrong oil can harm engine performance.
2. Remove the oil filler cap, usually marked with an oil can symbol.
3. Add a small amount at a time, then recheck the level with the dipstick.
4. Avoid overfilling — slow, measured additions are safer than pouring too much at once.

Tip: If you’re unsure, it’s better to add less and check again than risk overfilling.

Common Mistakes to Avoid

Even experienced drivers can make errors when checking oil. Avoid these pitfalls:

• Checking oil on a slope: Leads to false readings.
• Not wiping the dipstick first: Can overestimate the oil level.
• Reading at an angle: Eye-level reading ensures accuracy.
• Using the wrong oil type: Always follow the manufacturer’s specifications.
• Ignoring oil colour and consistency: Even if levels are fine, dirty oil can reduce engine life.
• Checking immediately after driving: Hot oil can be unevenly distributed and may cause burns.

Extra Tips for Australian Drivers

• Check more often in extreme temperatures: Hot summers or cold winters can affect oil performance and consumption.
• Use engine-friendly oil for your climate: Refer to your manual for the right viscosity for Australian conditions.
• Keep an emergency oil supply in the boot: Useful for topping up if you’re on a long road trip or in remote areas.
• Regular service checks: Even if you check oil monthly, routine service helps ensure your engine is fully protected.

When to Seek Professional Help

If you notice unusual oil consumption, leaks under your car, or a sudden drop in levels, consult a mechanic. Engine problems can escalate quickly, and professional inspection ensures you don’t risk costly damage.

Checking your oil regularly doesn’t take much time, but it makes a huge difference to your car’s performance and reliability. By following these simple steps and avoiding common mistakes, you can protect your engine, prevent breakdowns, and enjoy a smoother, safer drive. A little care today keeps your car running well for years to come.
