How Often Should You Change Your Car's Oil?
How often do I really need to change my car’s oil? Conventional wisdom has always put it at every 3,000 miles to prevent engine wear, but isn’t changing oil that frequently wasteful and unnecessary? Also, what is the "greenest" and longest-lasting oil I should use?
