36,000-MILE OIL CHANGE INTERVAL
The Northstar XV12 is designed for 36,000-mile intervals between oil changes. This is achieved through a combination of improved oil sensors and monitors, reduced oil consumption, oil cooling and a larger oil sump capacity.
The Northstar XV12 project began in late 1999. GM enlisted Cosworth Technology to assist in the project. GM developed the technologies for all the major systems and Cosworth Technology provided the engineering integration of these technologies.
