How does lubrication affect fuel economy?
One of the desired effects of adequate lubrication is the reduction of friction between and among moving metal parts. By reducing or eliminating friction, the engine is able to generate power at maximum efficiency. However, if there is low oil pressure, then there is also a commensurate increase in friction. This results in increased workload for the engine. In other words, your engine will have to work harder, causing a reduction in fuel economy.
What happens if oil leaks in engine?
Any leak within the oil passages of the engine can also result in low oil pressure. Instead of circulating through these passages, the oil will seep through cracks or other miniscule holes in the engine. In other words, the fluid that’s supposed to keep the motor well-lubricated escapes from the system.
Why does pressure drop when pumping oil?
Pressure can also drop because the pump is no longer functioning as it’s supposed to.

Why does my engine leak oil?
In some cases, if the valve guides have excessive clearance, the excess space can lead to a reduction in oil pressure. Modern vehicles also have a PCV valve for more efficient use of energy. Unfortunately, if this system fails, it can lead to an unnecessary buildup of pressure within the crankcase. This can push out the seals and gaskets, leading to an internal oil leak.
Where does the oil pump draw lubricant?
The oil pump draws lubricant from the bottom of an oil pan. There is a pipe that connects the oil pan to the oil pump. However, before the engine fluid gets drawn through the engine, it passes through a filter or strainer.
