The oil cap, displaying an oil can symbol, is usually mounted on top of the engine. To add engine oil, simply remove this cap to access the oil filler. Pour about half a quart at a time, using a funnel to prevent spills. Keep in mind not to overfill because too much oil may be just as harmful as too little. After adding about half a quart of oil, wait for about 50 to 60 seconds to allow it to settle properly, then recheck the dipstick. If the oil is still insufficient, add the remaining amount from the quart. Usually, one quart of oil should be enough, but if you need more, add it slowly to avoid adding excess oil. After adding oil at the right level, reinstall the oil cap in its original position and properly tighten it. Inspect for any spills and clean them up if needed. Finally, close your vehicle’s hood, and you're good to drive.
