• Unusual Engine Noises: If you hear knocking or tapping sounds coming from the engine, it may be a sign that the oil is not lubricating the engine components properly․
• Excessive Exhaust Smoke: Blue or gray smoke from the exhaust may indicate that your engine is burning oil, which could mean it’s time for a top-up․
• Oil Leaks: Puddles of oil under your car can indicate a leak․ Regularly check under your vehicle, especially if you notice a drop in oil levels․

DIY Oil Check and Top-Up Process

Performing an oil check and top-up is a relatively simple process․ Here’s a step-by-step guide to help you:

1. Park on Level Ground: Ensure your car is on a flat surface to get an accurate reading․
2. Wait for the Engine to Cool: Allow the engine to cool for at least five minutes to avoid burns and to get a precise oil level reading․
3. Check the Dipstick: Locate the dipstick, pull it out, wipe it clean, and reinsert it before checking the oil level․
4. Add Oil Carefully: If the oil is below the minimum mark, slowly pour in the appropriate oil using a funnel to prevent spills․
5. Recheck the Level: After adding oil, wait a moment, then check the dipstick again to ensure the level is now adequate․

When to Seek Professional Help
