Tell your doctor or dentist that you take calcium carbonate before you receive any medical or dental care, emergency care, or surgery.

Many newer vehicles now come equipped with an sensor or monitor where a light on comes on indicating you should change the oil. If you are lucky enough to have one of these you will soon realize how much of a waste it would be to change your oil every 3,000 miles.
Oil chemistry and engine technology have improved to the point that most cars can go several thousand more miles before changing the oil, Mr. Reed said. A better average, he said, would be 7,500 between oil changes, and sometimes up to 10,000 miles or more. The California Integrated Waste Management Board ran public service announcements for several years about âthe 3,000-mile myth,â urging drivers to wait longer between oil changes.
