"GM: 30,000-mile Drain Intervals Are Achievable
Typical drain intervals with General Motors' Oil Life System, the onboard computer algorithm that tells drivers when it's time to change their motor oil, are 8,500 miles, versus 5,000 for GM's competitors, a GM executive told last week's World Tribology Congress. Drain intervals over 30,000 miles are achievable with minor engine modifications and appropriate oil quality."
