The correct answer emphasizes the importance of maintaining proper oil levels for optimal engine performance and longevity. Checking your vehicle's oil level at least once a week or before long trips is a proactive measure to ensure that the engine has adequate lubrication. Insufficient oil can lead to increased friction, overheating, and ultimately severe engine damage.

Regular checks allow you to detect leaks or consumption issues early, preventing potential breakdowns or costly repairs. While checking oil levels monthly might seem sufficient, it doesn’t account for the wear and tear that can occur more rapidly, especially if driving frequently or under demanding conditions. Waiting until engine trouble is noticed can lead to situations where the damage has already occurred, making this an ineffective strategy for maintenance. Checking oil as part of a routine before refueling could be beneficial, but not everyone may refuel consistently or on a set schedule. Therefore, weekly checks or before long trips are deemed the best practice for ensuring your vehicle operates smoothly and reliably.
