Symptoms indicating the need for an oil change: The engine noise of the car will increase, which is caused by the thinning of the engine oil. Additionally, the engine oil pressure warning light may illuminate, as the thinning of the engine oil results in excessively low oil pressure. Engine oil, also known as engine lubricant, serves multiple functions including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, providing new characteristics and playing a crucial role in the lubricant's performance.
Oh, when it comes to symptoms that indicate the need for an oil change, I've encountered quite a few situations over my years of driving. The most common one is when the engine oil turns black or becomes as murky as muddy water—normally, it should be a clear, light brown color. If you open the cap and smell a burnt or pungent odor, that's bad news—it means the oil has deteriorated. When the engine makes louder noises upon startup, almost like it's grinding its teeth, that indicates insufficient lubrication, and components may be severely worn. Another sign is increased oil consumption—if you constantly need to top it up, it's clearly burning oil. If the oil pressure light on the dashboard comes on, get it checked immediately—don't wait for a breakdown on the road. Even a sluggish feeling while driving or slow throttle response can be a warning sign. Personally, I make it a habit to pull out the dipstick and check every 5,000 kilometers. Regular oil changes save money and keep you safe—delaying is never worth it. If the oil fails, engine repairs can be insanely expensive—don't cut corners to save hassle.
