CHANGING YOUR MOTOR OIL
Your owner's manual will tell you how often you should change your engine's oil. If you need an oil change, it's a simple task that is vital to the overall health of your vehicle's engine.
Your vehicle stores its motor oil in an oil pan typically bolted underneath the engine block. This oil pan is designed to hold a specific amount of oil, and it's important to check the oil periodically to make sure the oil level is within the range recommended by the vehicle manufacturer.
Typically, this means you should keep the oil level between the MIN and MAX lines on the dipstick. If it's low (below the MIN line on most dipsticks), then you should add oil as explained in your vehicle owner's manual or maybe consider getting an oil change.
Remember, oil level is important in an engine. Too much oil (above the MAX line) may cause parts of the crankshaft to dip into the oil and churn air into it, causing foaming/oil pressure fluctuation. Low oil levels (below the MIN line) can result in excessively high oil temperatures, since engine heat is more concentrated. An oil level that is too high or too low can also increase oil consumption.
