Periodic oil and filter changes help keep your engine clean on the inside.  Dust, metallic shavings, condensation and even antifreeze can contaminate motor oil.

Change oil and filter every 3,000 miles or three months.  Many car manufacturers recommend extended oil drain intervals for some drivers.  If you regularly make short trips in your car, drive in stop-and-go traffic, idle for extended periods, drive in dusty or dirty air conditions, tow a trailer or live in a cold-weather region - stay with the 3,000-mile/three month schedule. 

Regular oil changes are your best investment toward the longevity of your engine!
