  • What is high oil pressure?

    Q: What is high oil pressure?

    A: 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.

  • How can I switch to synthetic motor oil?

    Q: How can I switch to synthetic motor oil?

    A: Synthetic oil is not for old engines with their original seals, says HowStuffWorks. However, in modern engines, conventional oil can be switched with synthetic oil without any problem. The higher cost versus the benefit of synthetic oil is the only real consideration.

  • Is an engine oil flush necessary?

    Q: Is an engine oil flush necessary?

    A: An engine oil flush is not absolutely necessary for most cars, but it is beneficial in instances in which there is a significant possibility of carbon deposit build up. When large amounts of carbon build up in the oil system, the car's oil cannot flow as intended, which leads to serious engine problems. If the oil is changed regularly, however, the gunk in the car's oil system usually does not have enough time to build up to a harmful level.
