What are the effects of having slightly less engine oil in a car?

The effects of having slightly less engine oil in a car include: 1. Causing bearing seizure leading to severe engine failure; 2. Accelerating engine wear; 3. Affecting the engine lubrication system and piston heat dissipation. If the engine oil is low, it can be topped up, but it is important to note that the added oil must be the same brand and type, as other specifications cannot be mixed. The functions of engine oil are: 1. Lubrication and friction reduction; 2. Assisting in cooling; 3. Sealing and preventing leaks; 4. Rust and corrosion prevention; 5. Shock absorption and cushioning. The steps for changing engine oil are: 1. Lift the car, remove the protective plate, and place a container under the drain plug; 2. Unscrew the drain plug, use an air gun to blow for two minutes at the oil filler port, then tighten the drain plug after draining and wipe it with a tissue to check for leaks; 3. Reinstall the protective plate, lower the car, and use a funnel to add oil through the filler port.
I've been driving for over twenty years and often encountered situations where the engine oil was a bit low. Honestly, the impact is quite noticeable. Low oil level means insufficient lubrication, leading to increased friction between engine components during operation, which results in significantly louder noise—especially on highways, where you can hear that harsh whining sound. Over time, parts are more prone to wear, particularly critical components like pistons and crankshafts. Once they wear out, a major overhaul is needed, and the repair costs are no joke. Additionally, the oil's cooling effect diminishes, especially during hot summers when engine temperatures can spike easily, increasing the risk of having to pull over or even breaking down. I recommend taking a moment each month to check the oil dipstick and ensure the level stays within the marked range. If the oil level drops shortly after a change, check for potential leaks, like aging seals. In short, don’t ignore low oil levels—address it early to avoid bigger headaches. After all, we treat our cars like they’re our lifelines.
