High oil pressure occurs when an unusually high amount of pressure is required to circulate oil through the engine of a car. Most cars have oil pressure gauges that show how much pressure is used to circulate the oil. After a car runs for approximately 20 minutes, the needle on the gauge should settle at the midpoint. If it settles toward the top of the gauge, this indicates high oil pressure.Know More
High oil pressure is a serious problem that leads to engine failure in a matter of minutes. If the problem is not fixed, or a car continues to run with high oil pressure, the whole engine may need to be replaced.
There are a few different causes of high oil pressure. The most common cause is a bad pressure relief valve. This auto part is responsible for regulating the oil pressure in a car and preventing it from getting too high. Another possible cause of high oil pressure is a blockage in the oil delivery lines. There are many different components the oil passes through to lubricate the engine. Even the smallest blockage can cause high oil pressure. Lastly, a malfunctioning oil pump can restrict the flow of oil and cause oil pressure to increase.Learn More
Topping off the oil in a vehicle to the point that it overflows can cause the additional oil in the oil pump to build pressure on the seal on the rear main bearing. As a result, the pressure on the rear main bearing can burst or rupture, ultimately causing oil to leak from the vehicle.Full Answer >
Although most people still have the oil in their car changed every 3,000 miles, most experts suggest that synthetic oil only needs to be changed after 5,000 to 7,500 miles. However, some manufacturers list oil change intervals as high as 10,000 or even 15,000 miles when using synthetic oil.Full Answer >
To change the oil in a vehicle, remove the oil plug and allow the oil to drain into an approved container. Replace the oil plug, and install a new oil filter before adding new oil. Changing the oil in a vehicle typically takes about an hour.Full Answer >
Synthetic oil, which is manmade in a laboratory as opposed to being derived from crude oil, is more stable at a variety of temperatures and has a more consistent molecular structure. Because of this, synthetic oil helps engines run cooler, provides better lubrication at higher temperatures and lasts longer.Full Answer >
