What happens when engine oil is low?

[WillowLynn]

Insufficient engine oil will increase engine wear. Prolonged oil deficiency can lead to severe burning and damage to the engine, resulting in abnormal operation. When the oil level in the engine oil pan is too low, contact areas such as bearings and journals will experience poor lubrication due to insufficient oil, accelerating wear and potentially causing bearing seizure or shaft locking. 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. It is often referred to as the "blood" of a car. Engine oil consists of base oil and additives, with the base oil being the primary component that determines the fundamental properties of the lubricant.

Running low on engine oil is no joke. As someone who's driven for years, I know how crucial this is. Engine oil primarily lubricates internal engine components, reducing friction and cooling things down. If oil levels are insufficient, increased friction between parts during operation can lead to overheating and even damage critical areas - think piston or bearing failures. In severe cases, it might cause bearing seizure, completely wrecking the engine. Additionally, fuel consumption rises, the car loses power, and noise levels increase like you're dragging extra weight. Long-term neglect may also increase exhaust emissions, harming the environment. My advice: regularly check the dipstick when the engine is cold to ensure levels stay between the min/max marks. If low, promptly top up with the correct oil (but don't overfill). Timely oil changes during routine maintenance are vital - don't wait for warning lights to act.

As an ordinary driver, I've experienced the trouble of low engine oil. Once, I forgot to check it, and the car started making a hissing sound. When I took it for repairs, I found out the engine had overheated and damaged some parts, costing me over a thousand yuan to fix. Insufficient engine oil increases friction in the engine, causing temperatures to soar, which can burn out precision components and also increase fuel consumption. For example, where I used to get 500 kilometers on a full tank, now it's gone after just over 400. From a safety perspective, it's even more critical—the risk of a sudden breakdown on the highway is too high. I've developed a habit of checking the oil level by opening the hood every two weeks, topping it up immediately if it's low. Remember, high-quality engine oil can extend the engine's lifespan and save on maintenance costs—don't skimp on small expenses only to spend big later.

As a new driver who just bought my first car, I pay great attention to details. Low engine oil can cause serious problems - it lubricates the engine internals and protects components from friction. If oil level is low, the engine may overheat or even get damaged, which would be expensive to repair. My friend's car had to get a complete engine replacement because of this. Symptoms include strange engine noises, reduced power, and increased fuel consumption. I've learned a simple routine: regularly check the dipstick when the engine is cold, and add some oil if it's below the Min line. Never delay this, or minor issues could turn into major failures.
