The oil pump pushes oil through passages that end up in bearings and other components. The pressurized oil leaks out past small openings around the bearings, and as the bearings wear out the openings become larger.
When the oil is cold it is thicker and when the oil is warm it becomes less "viscous", yet the oil pump continues to pump the same volume of oil. Thicker oil leaks past the openings around the bearings a little more slowly.
When the engine is running faster the oil pump is also turning faster, and moving more oil through the passages. Yet the oil still leaks past the bearings at the same rate.
In other words, if your engine is getting worn, change the oil to a higher viscosity (higher numbers, ie, If you're currently using 5W15, change to 10W30 or even 15W50 if necessary).
If your engine isn't quite as new as it once was, changing to a heavier (higher viscosity) oil can give you a LOT more miles.
Above the bubble-point pressure, the oil formation volume factor decreases. This is due to the expansion of gas released from the oil as pressure decreases, causing the volume of oil to increase for a given mass.
Factors that can cause oil viscosity to decrease include an increase in temperature, shearing forces from mechanical stress, contamination by fuel or other solvents, and oxidation or degradation of the oil over time.
When oil is heated, its volume increases due to thermal expansion. This is because the heat causes the oil molecules to move faster and spread out, leading to an overall increase in volume. Additionally, the expansion of the oil can also be attributed to the decrease in its density as it becomes less dense when heated.
Oil expands about 0.07% for each degree Celsius increase in temperature. This expansion can lead to changes in volume, pressure, and viscosity in the oil.
The price of oil went up after Hurricane Katrina due to the disruption of oil production and refining facilities in the Gulf of Mexico region. The hurricane caused widespread damage to infrastructure, leading to a decrease in supply which drove up oil prices. Additionally, concerns about potential long-term impacts on production further contributed to the increase in prices.
An increase in the price of heating oil causes a decrease in the quantity of heating oil demanded.
Above the bubble-point pressure, the oil formation volume factor decreases. This is due to the expansion of gas released from the oil as pressure decreases, causing the volume of oil to increase for a given mass.
The quotation is incorrect: An increase in price causes a decrease in the quantity demanded, not a decrease in demand.
The opposite of a 0.25 cent oil increase is a 0.25 cent oil decrease.
High oil pressure or a faulty oil pressure gauge.
Not enough oil pressure and / or the oil channel is plugged
Too much oil, excessive crankcase pressure ( bad piston rings ) or both. pressure causes oil to come the filter tude and capilarity is also a factor. pressure causes oil to come the filter tude and capilarity is also a factor.
Not enough oil.
Compromised oil system, faulty engine oil rifle pressure 1 sensor.

One of the causes for low oil pressure in a Chevy Tahoe could be a clogged or dirty oil filter. Changing the filter may get rid of the problem.
the normal oil pressure should equal to at leasr 10 pounds per 1000 rpm's my 1992 runs abt. 40-50 Psi while cruising. It will go up and down as RPMs increase or decrease
