Tell your doctor or dentist that you take calcium carbonate before you receive any medical or dental care, emergency care, or surgery. Lab tests, including serum calcium levels, may be performed while you use calcium carbonate. These tests may be used to monitor your condition or check for side effects.
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.
Most carmakers abandoned the 3,000-mile (4,828-kilometer) interval long ago, opting instead to advise their customers to go 5,000 or 7,500 miles (8,046 or 12,070 kilometers) between oil changes [source: MEMA]. Some people even go 10,000 miles (16,093 kilometers) or more without any guilt -- or damage to the engine. The 3,000-mile guideline dates back to a time when motor oil wasn't quite as advanced as it is now.
