Whether you race down the back straight-a-way on the weekends or race to get your kids and their friends to the movie on time on weekends, you need to monitor your oil pressure. If your oil pressure suddenly drops to zero you know that there is big trouble in store. If your oil pressure does not get to the proper operating pressure it could be a warning that something is leaking or a gasket is beginning to fail.
