What does the yellow oil light mean?

The yellow oil light is a signal provided by the oil level sensor, indicating either an oil maintenance reminder or low oil level. It is recommended to promptly inspect the engine, drive the vehicle to a repair shop, add oil, and perform maintenance checks. Since the engine is the heart of the vehicle, regular and timely maintenance is essential to avoid breakdowns during operation. The oil light is a component that monitors normal oil pressure. Only proper oil pressure ensures that oil is delivered to all friction surfaces of the engine. Both excessively high and low oil pressure can affect the engine's normal operation and even cause damage to engine components. Therefore, when the oil light alerts, the engine should be stopped immediately to identify the cause, and operation should only resume after the issue is resolved.
That time when the yellow warning light came on while I was driving on the highway was really scary! The yellow oil light indicates low oil pressure, most commonly due to insufficient oil level - you need to pull over and check immediately. Use the dipstick to measure; if the oil level is low, top it up but don't overfill as it may cause leaks or oil burning. If the light stays on after refilling, it could indicate oil pump failure, faulty sensor, or clogged oil passages. Never keep driving as engine overheating can cause serious damage with expensive repairs. I was lucky to handle it promptly that time, and now I've developed the habit of checking oil level every few thousand kilometers - it's saved me major trouble. Keeping a spare bottle of oil in the trunk also helps deal with emergencies during trips.
