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.
But based on how relatively simple it is to perform this type of vehicle maintenance and how vital it is to your engine, the traditional three months and 3,000 miles (4,828 kilometers) standard is still a good interval for changing out the oil.
