You should check the engine oil level when the car is parked on level ground and the engine is off. It is generally best to wait about 5 to 10 minutes after turning off a warm engine to allow the oil to settle into the oil pan for an accurate reading. Checking the oil when the engine is warm (but not hot) is often recommended, as the oil has circulated and will give a better indication of the true level. It is also advisable to check oil regularly, such as every few weeks, and always before a long journey. Safety is important, so always check the oil with the engine off to avoid burning yourself with hot engine parts.

Key points for checking oil level:

• Park on flat, level ground.
• Turn off the engine and wait 5-10 minutes if recently driven.
• Locate and pull out the dipstick, wipe it clean, then reinsert and remove again to check the level.
• Oil level should fall between the minimum and maximum marks on the dipstick.
• Check oil at regular intervals, at least every few weeks.
• Check before long trips to ensure proper oil level.

These guidelines ensure an accurate and safe oil level check for maintaining engine health.
