The Role of Motor Oil

Motor oil has four main functions.  First, it lubricates so that engine components will pass by one another without friction, which can cause loss of power.  A second closely related function is protection against wear and corrosion.  A motor oil must combat the acids which are a byproduct of the combustion process to prevent corrosion of engine parts.  Third, a motor oil must clean by keeping deposits from forming and holding contaminants in suspension until they are removed by the oil filter.  Finally, motor oil must cool your engine.  As it passes through your system, it is directed onto the hot surfaces within your engine in order to carry the heat away to the oil pan.

How does it do this? Your oil pump draws oil from the oil pan and forces it through the oil filter.  It is then pushed throughout the engine to lubricate the components.  One cannot underestimate the importance of this process.  Engine (and car) life can be extended as long as 200,000 to 300,000 miles when proper motor oil use is combined with sensible oil drains.  A smart car owner would be foolish not to research this topic and take steps to get the best possible motor oil for their vehicle and their needs.  As well as extending your engine's lifespan,  a good motor oil can prevent costly repairs, improve fuel mileage and also improve performance.
