Both ends of oil can be harmful if it’s too much or too little. In addition, it can lead to bad things such as friction between moving components rising, causing the engine to run hotter, and, in the worst-case scenario, moving parts may seize due to a lack of lubrication. Some of the solutions and problems are explained below for drivers in Nigeria

Too much oil can lead to foaming, transforming a slick lubricant into a frothy fluid with air bubbles, reducing the lubricating and cooling characteristics. Frothy oil is also more difficult for the oil pump to distribute throughout the engine. As a result, some moving components may not receive as much oil as they require, resulting in increased wear and the possibility of engine damage.

Most of the engines require between 4 to 6 quarts. Normally, the oil drains into a pan at the engine's bottom. When the pan is overfilled, the crankshaft acts as a high-speed blender, churning the oil and producing froth. 

The crankshaft monitors the engine speed, and it rotates quickly when the engine is turned on. For example, if the tachometer displays 2,500 rpm at 75 mph, that implies the crankshaft completes 2,500 revolutions per minute; floor the throttle, and it can reach 5,000 rpm or more.

It also raises oil pressure, placing additional strain on seals and gaskets that prevent oil from seeping out of the engine or entering areas it shouldn't on the interior. The extra load promotes wear on the seals and gaskets over time. Overloading of the oil is common in repair businesses because they pump fresh oil from bulk containers rather than pouring it from quart or gallon-size containers. Holding the pump trigger for a lengthy amount of time may cause additional oil to be added, and the technician may miss checking the dipstick. Because oil takes time to drain into the pan, the technician may get an erroneous reading of the oil level shortly after pumping in more oil.

The oil dipstick will give an accurate reading once the engine is cold and flat ground. If the oil is above the mark, it will not cause any such problem, but if it’s overfilled, you may notice foam or frothy oil. You need to oil drain it and refill it to the proper level to fix that.
