However, even the most reliable vehicles require regular attention, and checking the engine oil is arguably the most critical of these routine tasks. Neglecting this can lead to increased wear and tear, overheating, and in severe cases, catastrophic engine failure. Therefore, understanding how to perform this check correctly is an investment in your car's future.

### Why Checking Engine Oil is Crucial

Engine oil serves multiple vital functions within your Peugeot 107. It lubricates moving parts, reducing friction and wear between components like the pistons, crankshaft, and camshaft. Without adequate lubrication, these parts would grind against each other, generating excessive heat and leading to rapid deterioration. Oil also plays a crucial role in cooling the engine by absorbing heat generated during combustion and carrying it away to the oil sump. Furthermore, it cleans the engine by suspending dirt, debris, and combustion by-products, which are then filtered out. Finally, it helps to seal the gap between the piston rings and cylinder walls, maintaining compression and preventing combustion gases from leaking into the crankcase. A low oil level compromises all these functions, leading to increased engine temperature, greater mechanical stress, and a significant reduction in the engine's lifespan. It's also worth noting that low oil pressure can trigger warning lights on your dashboard, but it's always best to check the level proactively.

### What You'll Need

Before you begin, gather the following items:

• A clean, lint-free cloth or paper towel
• Your Peugeot 107's owner's manual (optional, but recommended for specific details)
• A flat, level surface to park your car on
• A well-lit area

### Step-by-Step Guide to Checking Your Peugeot 107's Engine Oil

Follow these steps carefully to ensure an accurate reading:

1. Park on a Level Surface: This is paramount for an accurate oil level reading. Parking on a slope will result in an incorrect measurement, either falsely indicating a high or low level. Ensure the car is parked on a flat, horizontal surface.

2. Warm Up the Engine (Slightly): For the most accurate reading, the engine oil should be at its operating temperature. However, you don't want it to be scalding hot. Drive your car for a few minutes, or let it idle for about 5-10 minutes. This allows the oil to circulate properly and reach a state where its volume is representative. Avoid checking the oil immediately after a long journey when the engine is extremely hot.

3. Turn Off the Engine: Once the engine has reached a suitable temperature, switch it off. Wait for at least 5-10 minutes. This waiting period is crucial as it allows the oil that has circulated throughout the engine to drain back down into the oil sump, providing a more accurate reflection of the actual oil level.

4. Locate the Dipstick: Open the bonnet (hood) of your Peugeot 107. The engine oil dipstick is typically a brightly coloured loop or handle, often yellow or orange, to make it easily identifiable. It will usually have an oil can symbol or the word "OIL" printed on it. Consult your owner's manual if you have trouble locating it. The dipstick is usually situated towards the front or side of the engine block.

5. Remove and Wipe the Dipstick: Carefully pull the dipstick all the way out of its tube. Use your clean, lint-free cloth or paper towel to wipe the entire length of the dipstick clean, especially the end where the oil level markings are located. This ensures that no residual oil from previous checks or from the dipstick tube itself interferes with the reading.

6. Reinsert the Dipstick: Fully reinsert the clean dipstick back into its designated tube. Push it in until it is seated correctly. Ensure it goes all the way in; a partially inserted dipstick will give a false low reading.

7. Remove and Read the Dipstick Again: Carefully pull the dipstick out once more. Hold it horizontally and examine the end. You should see two markings, usually small holes or lines, indicating the minimum and maximum oil levels. The oil film on the dipstick should be between these two marks.

8. Interpreting the Reading:
* If the oil level is between the two marks: This is the ideal scenario. Your engine oil level is correct.
* If the oil level is at or below the lower mark: Your engine oil level is too low. You will need to add oil. Refer to the next section on how to add oil.
* If the oil level is above the upper mark: This indicates that the oil level is too high. Overfilling can be as detrimental as having too little oil, potentially causing foaming and damage to seals. In this case, you may need to drain a small amount of oil.

9. Check for Oil Condition: While the dipstick is out, take a moment to inspect the condition of the oil. Healthy engine oil should be amber or light brown in colour. If the oil appears very dark, thick, sludgy, or contains metallic particles, it may be time for an oil change. The smell of the oil can also be an indicator; a burnt smell suggests the oil may be overheating or breaking down.

10. Replace the Dipstick: Once you have finished checking the level and condition, reinsert the dipstick firmly into its tube. Ensure it is fully seated to prevent it from vibrating loose during driving.

11. Close the Bonnet: Securely close the bonnet of your Peugeot 107.

### Adding Engine Oil

If your dipstick indicates that the oil level is low, you will need to add oil. It is crucial to use the correct type and grade of engine oil specified for your Peugeot 107. Consult your owner's manual for the exact specifications. For the 2007 Peugeot 107, a common recommendation is a 0W-30 or 5W-30 fully synthetic engine oil that meets specific PSA (Peugeot Société Anonyme) approvals. Adding oil should be done gradually.

1. Locate the Oil Filler Cap: This cap is usually marked with an oil can symbol and the word "OIL" or "ENGINE OIL". It is typically located on the top of the engine.

2. Remove the Filler Cap: Unscrew and remove the oil filler cap.

3. Add Oil Slowly: Using a funnel, add a small amount of the correct engine oil (e.g., about half a litre or half a pint at a time). Do not overfill. It is much easier to add more oil than to remove excess oil.

4. Wait and Recheck: Replace the filler cap, wait a few minutes for the oil to settle in the sump, and then recheck the dipstick level using the steps outlined above. Repeat the process of adding small amounts of oil and rechecking until the oil level is within the recommended range (between the MIN and MAX marks).

5. Final Check: Once the level is correct, ensure the oil filler cap is securely tightened and the dipstick is properly seated. It's a good idea to start the engine and let it run for a minute or two, then switch it off and wait for 5-10 minutes to perform a final dipstick check to confirm the level is still within the correct range.

### What If the Oil Level is Too High?

An overfilled engine can cause significant problems, including increased oil pressure, damage to the crankshaft seal, and the oil becoming aerated (foamy), which reduces its lubricating properties. If you have overfilled your Peugeot 107, the best course of action is to carefully drain a small amount of oil from the sump. This usually involves locating the drain plug at the bottom of the oil pan, placing a suitable container underneath, and carefully unscrewing the plug just enough to let a small quantity of oil out. It's a delicate process, and if you are unsure, it is best to seek assistance from a qualified mechanic. Alternatively, some garages have a vacuum extraction system that can remove oil from the filler cap opening.

### How Often Should You Check Your Engine Oil?

For optimal engine health, it's recommended to check your Peugeot 107's engine oil level at least once a month, and before any long journeys. Regular checks are a proactive measure that can save you from costly repairs down the line. The service intervals for oil changes will vary based on mileage and driving conditions, but generally, it's advisable to change the oil and filter according to the manufacturer's recommendations, typically found in your owner's manual. For many small city cars like the 107, this might be around every 10,000 to 15,000 miles or annually, whichever comes first.
