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.
Oil change frequency: Miles vs. Time. When I get an oil change, the mechanic usually affixes a sticker to my windshield telling me to get another oil change after 3,000 miles or six months. Now that I'm retired, it sometimes takes well over a year to go 3,000 miles (I live in a city, near an excellent public transit system).
