Regularly checking and maintaining the engine oil level is crucial for the longevity, performance, and reliability of your Mercedes-Benz R107. Oil lubricates the engine’s moving parts, reduces friction, and helps dissipate heat. Below is a step-by-step guide on how to properly check and maintain your engine oil level.
When and How to Check Engine Oil Level
📌 Best Time to Check:
- When the oil is warm, such as during a fuel stop.
- Ensure the vehicle is on level ground.
- Stop the engine and wait a few minutes for the oil to settle in the pan.
Step 1: Locate and Prepare the Dipstick

1 – Oil dipstick 2 – Oil filler cap
✅ Open the hood and locate the engine oil dipstick.
✅ Pull out the dipstick and wipe it clean with a lint-free cloth.
✅ Reinsert the dipstick fully, then remove it again to check the level.
Understanding the Oil Level Reading

📌 The dipstick has two marks:
- Minimum (min) – The lowest acceptable level.
- Maximum (max) – The full level (do not exceed).
✅ If oil is near the minimum mark: Add oil until it reaches but does not exceed the max mark.
🚫 DO NOT overfill – Overfilling can lead to excessive pressure, leaks, and engine damage.
Low Engine Oil Level Indicator Lamp
📌 Your Mercedes-Benz R107 has an engine oil level warning light that helps monitor oil levels.
✅ When the ignition key is in position 2: The oil level indicator lamp should illuminate briefly and then turn off when the engine starts.
🚨 If the lamp stays on while driving:
- The engine oil level has dropped to approximately the minimum mark on the dipstick.
- If it starts coming on intermittently, it indicates oil is low but still within an operational range.
- If the light remains constantly ON, you must immediately check and refill the engine oil.
How to Add Engine Oil
✅ Use only the recommended oil for your Mercedes-Benz R107 (refer to the owner’s manual for specifications).
✅ Pour oil slowly through the oil filler cap.
✅ Check the level again with the dipstick after adding oil.
✅ Ensure the cap is securely tightened after refilling.
🚨 Warning:
- Never overfill – excess oil can cause leaks or damage seals.
- Avoid mixing different oil types, as this can affect engine performance.
Final Tips for Engine Oil Maintenance
✅ Regularly check the oil level during fuel stops or before long trips.
✅ Monitor the oil level warning light—it’s an early alert for low oil.
✅ Use the correct oil type and viscosity for optimal performance.
✅ Schedule regular oil changes to maintain engine health.
By following these simple steps, you can prolong the life of your Mercedes-Benz R107 engine and ensure smooth and reliable performance. 🚗🔧
