Amsoil recommends 25,000 miles or once a year with filter changes every six
months for some of its products. Mobil 1 says follow the vehicle
manufacturer's recommendations: "Oil change intervals can be as short as
3,000 miles or as long as 15,000 miles on some new cars." Redline
recommends between 12,000 and 18,000.
