Most cars hold 5 to 8 quarts of engine oil. Also known as motor oil, it plays a vital role in protecting automotive engines from damage. It lubricates the engine's moving parts, removes contaminants, and reduces heat, all of which are essential to making an engine last. If your car is leaking engine oil, though, you might be wondering what happens if it runs dry.
Oil Pressure Light
One of the first things you may notice if your car is low on engine oil is an illuminated "oil pressure" light on the dashboard. The onboard computer is designed to measure oil pressure to ensure that it's an appropriate amount. Depending on the specific type of engine, it may have about 10 pounds per square inch (PSI) of pressure for every 1,000 resolutions per minute (RPM). Lack of oil, however, can prevent the engine from achieving this amount of oil pressure, in which case the "oil pressure" light will turn on.
You may also discover your car's engine overheating if it's out of oil. Some drivers assume that a healthy automotive cooling system will protect their car's engine from overheating. While the cooling system -- radiator, radiator cap, hoses, thermostat and heater core -- are essential to protecting against overheating, low or no engine oil can also cause engine temperatures to increase. According to Military.com, up to 80% of "waste heat" generated by automotive engines is removed by the oil. Without oil, or with an insufficient amount of oil, this waste heat will accumulate while simultaneously increasing the engine's temperature.
Bearings are the moving parts of an engine that support its crankcase. During combustion, these bearings move to produce the energy that powers the car. Normally, oil is pumped to the bearings where it lubricates and protects them from damage. Loss of oil, however, will result in the bearings rubbing directly against each other, which can quickly cause them to fail and the engine to seize. When this happens, you may hear a distinct "knocking" sound, or your car may fail to turn on at all.
Protect Your Engine From Damage
To protect your car's engine from potentially catastrophic damage, you must ensure there's adequate oil present at all times. At least once a week, pull the dipstick to inspect your car's oil levels. The dipstick should read somewhere in the middle, indicating that there's an appropriate amount of oil present to keep the engine running healthy.
Unless your car has headers, it probably has a manifold through which exhaust gases exit the engine. When exhaust gases are produced by the engine during combustion, they are pushed out the exhaust manifold. Most exhaust manifolds are made of iron or steel, allowing them to withstand hot temperatures -- sometimes reaching as high as [...]
Can't seem to start your car in cold weather no matter how many times you turn the ignition? It's frustrating when you're headed out the door for your normal morning commute, only to discover that your car won't start. While this problem can occur anytime of the year, however, it's most common during winter when [...]
Motor oil plays a vital role in the health of your vehicle's engine. It lubricates the moving components, reduces heat and prevents the accumulation of sediment from inside the engine. Like coolant, motor oil is contained in a closed system, meaning you shouldn't have to "top it off." If you discover your vehicle's oil levels [...]
The radiator is the single most important component in your vehicle's cooling system. Comprised of many narrow metallic tubes, it allows for the expulsion of heat through the front of your vehicle. Hot coolant flows from the engine to the radiator, at which point a fan cools off the coolant before sending it back into [...]
Do you struggle to keep your car's floor mats in place? This is an all-too-common problem encountered by drivers. Normally, a slipped floor mat won't cause any problems. But there's always the possibility that it will get stuck underneath your gas or brake pedal, preventing you from pressing down on it. As a result, it's [...]
Air conditioning is essential to creating a comfortable environment inside your vehicle. When summer arrives, you'll probably find yourself turning on the air conditioner while driving to stay cool. Like residential air conditioning, though, the climate control system in your vehicle contains a variety of parts. By familiarizing yourself with the components of automotive air [...]
Cars are often described as running rich or lean, depending on their ratio of fuel to air consumption. All combustion-powered gas engines burn a combination of air and fuel. As these ingredients into combustion chamber, a spark ignites them to produce power. However, different ratios of air to fuel can cause a car to run [...]
A blown head gasket is an all-too-common problem experienced by drivers. Even with low-mileage vehicles, the head gasket may blow, thereby increasing the risk of serious and potentially catastrophic engine damage. Unless you're familiar with the automotive mechanics, though, you might be wondering what is a blown head gasket.Head Gaskets ExplainedTo better understand a blown [...]
Washing your car with soap and water is only one step in maintaining a clean, pristine clear coat. It's also important that you wax it. Wax adds an extra layer of protection, thereby protecting the clear coat and underlying paint layers from moisture, dirt and debris. Neglecting to wax your car on a regular basis [...]
